An Ebola virus epidemic in Sierra Leone occurred in 2014, along with the neighbouring countries of Guinea and Liberia. At the time it was discovered, it was thought that Ebola virus was not endemic to Sierra Leone or to the West African region and that the epidemic represented the first time the virus was discovered there.[2] However, US researchers pointed to lab samples used for Lassa fever testing to suggest that Ebola had been in Sierra Leone as early as 2006.[3]
In 2014, it was discovered that samples of suspected Lassa fever showed evidence of the Zaire strain of Ebola virus in Sierra Leone as early as 2006.[3] Prior to the current Zaire strain outbreak in 2014, Ebola had not really been seen in Sierra Leone, or even in West Africa among humans.[3] It is suspected that fruit bats are natural carriers of disease, native to this region of Africa including Sierra Leone and also a popular food source for both humans and wildlife.[3] The Gola forests in south-east Sierra Leone are a noted source of bushmeat.[4]
Fruit bats gather on a tree in West Africa.
Bats are known to be carriers of at least 90 different viruses that can make transition to a human host.[5] However, the virus has different symptoms in humans.[5] It takes one to ten viruses to infect a human but there can be millions in a drop of blood from someone very sick from the disease.[6][7] Transmission is believed to be by contact with the blood and body fluids of those infected with the virus, as well as by handling raw bushmeat such as bats and monkeys, which are important sources of protein in West Africa. Infectious body fluids include blood, sweat, semen, breast milk, saliva, tears, feces, urine, vaginal secretions, vomit, and diarrhea.[8]
Even after a successful recovery from an Ebola infection, semen may contain the virus for at least two months.[9] Breast milk may contain the virus for two weeks after recovery, and transmission of the disease to a consumer of the breast milk may be possible.[10] By October 2014, it was suspected that handling a piece of contaminated paper may be enough to contract the disease.[11] Contamination on paper makes it harder to keep records in Ebola clinics, as data about patients written on paper that gets written down in a "hot" zone is hard to pass to a "safe" zone, because if there is any contamination it may bring Ebola into that area.[11]
One aspect of Sierra Leone that is alleged to have aided the disease, is the strong desire of many to have very involved funeral practices.[12] For example, for the Kissi people who inhabit part of Sierra Leone, it is important to bury the bodies of the dead near them.[12] Funeral practices include rubbing the corpses down with oil, dressing them in fine clothes, then having those at the funeral hug and kiss the dead body.[12] This may aid the transmission of Ebola, because those that die from Ebola disease are thought to have high concentrations of the virus in their body, even after they have died.[12]
For the 2001 outbreak of Sudan virus in Uganda, attending a funeral of an Ebola victim was rated by the Centers for Disease Control and Prevention (CDC) as one of the top three risk factors for contracting Ebola, along with contact with a family member with Ebola or providing medical care to someone with a case of Ebola virus disease.[13] The main start of the outbreak in Sierra Leone was linked to a single funeral in which the World Health Organization (WHO) estimates as many as 365 died from Ebola disease after getting the disease at the funeral.[14]
Bushmeat has also been implicated in spreading Ebola disease, either by handling the raw meat or through droppings from the animals.[15] It is the raw blood and meat that is thought to be more dangerous, so it is those that hunt and butcher the raw meat that are more at risk as opposed to cooked meat sold at market.[16] Health care workers in Sierra Leone have been warned not to go to markets.[17]
In late March 2014, there were suspected but not confirmed cases in Sierra Leone.[18] The government announced on 31 March 2014, that there were no cases in Sierra Leone.[19] Cases initially started appearing soon after the arrival of US researchers into the area. "After Ebola was first confirmed by laboratory tests in mid-March 2014, persistent rumours in the region linked the outbreak to a US-run research laboratory in Kenema, Sierra Leone (Wilkinson, 2017)."[20]
Two U.S. doctors who "followed all CDC and WHO protocols to the letter" contracted Ebola, and it is not clear how they got infected.[21]
By 27 May 2014, it was reported 5 people died from the Ebola virus and there were 16 new cases of the disease.[22][23] Between 27 May 2014, and 30 May the number of confirmed, probable, or suspected cases of Ebola went from 16 to 50.[24] By 9 June, the number of cases had risen to 42 known and 113 being tested, with a total of 16 known to have died from the disease by that time.[25]
The disease spread rapidly in Kenema, and the local government hospital was overwhelmed.[14] At that hospital, 12 nurses died despite having the world's only Lassa fever isolation ward, according to the U.N.[14] Many health are workers were infected at the state hospital, including beloved physician and hemorrhagic fever expert, Dr. Sheik Humarr Khan, and chief nurse Mbalu Fonnie. Khan and his colleagues had bravely provided care to patients with this devastating illness. [26]

At this hospital in Kenema, samples were tested for Ebola. (Shown in June 2014)
On 12 June, the country declared a state of emergency in the Kailahun District, where it announced the closure of schools, cinemas, and nightlife places; the district borders both Guinea and Liberia, and all vehicles would be subject to screening at checkpoints.[27][28] The government declared on 11 June, that its country's borders would be closed to Guinea and Liberia; but many local people cross the borders on unofficial routes which were difficult for authorities to control.[29][30] Seasonal rains that fall between June and August interfered with the fight against Ebola, and in some cases caused flooding in Sierra Leone.[31]
By 11 July 2014, the first case was reported in the capital of Sierra Leone, Freetown, however the person had traveled to the capital from another area of the country.[32] By this time there were over 300 confirmed cases and 99 were confirmed to have died from Ebola.[32] There was another case before the end of the month.[33]
On 29 July, well-known physician Sheik Umar Khan, Sierra Leone's only expert on hemorrhagic fever, died after contracting Ebola at his clinic in Kenema. Khan had long worked with Lassa fever, a disease that kills over 5,000 a year in Africa. He had expanded his clinic to accept Ebola patients. Sierra Leone's president, Ernest Bai Koroma, celebrated Khan as a "national hero".[34] On 30 July, Sierra Leone declared a state of emergency and deployed troops to quarantine hot spots.[35]
In August, awareness campaigns in Freetown, Sierra Leone's capital, were delivered over the radio and through loudspeakers.[36] Also in August, Sierra Leone passed a law that subjected anyone hiding someone believed to be infected to two years in jail. At the time the law was enacted, a top parliamentarian was critical of failures by neighboring countries to stop the outbreak.[37] Also in early August Sierra Leone cancelled league football (soccer) matches.[38]
September 2014: Exponential growth, quarantines

Within 2 days of 12 September 2014, there were 20 lab-confirmed cases discovered in Freetown, Sierra Leone.[39] One issue was that residents were leaving dead bodies in the street.[39] By 6 September 2014, there were 60 cases of Ebola in Freetown, out of about 1100 nationwide at this time.[40] However, not everyone was bringing cases to doctors, and they were not always being treated.[40] One doctor said the Freetown health system was not functioning, and during this time, respected Freetown Doctor Olivette Buck fell ill and died from Ebola by 14 September 2014.[40][41] The population of Freetown in 2011 was 941,000.[42]
By 18 September 2014, teams of people that buried the dead were struggling to keep up, as 20–30 bodies needed to be buried each day.[43] The teams drove on motor-bikes to collect samples from corpses to see if they died from Ebola.[43] Freetown, Sierra Leone had one laboratory that could do Ebola testing.[43]
WHO estimated on 21 September, that Sierra Leone's capacity to treat Ebola cases fell short by the equivalent of 532 beds.[44] Experts pushed for a greater response at this time noting that it could destroy Sierra Leone and Liberia.[45] At that time it was estimated that if it spread through both Liberia and Sierra Leone up to 5 million could be killed;[46] the population of Liberia is about 4.3 million and Sierra Leone is about 6.1 million.
In an attempt to control the disease, Sierra Leone imposed a three-day lockdown on its population from 19 to 21 September. During this period 28,500 trained community workers and volunteers went door-to-door providing information on how to prevent infection, as well as setting up community Ebola surveillance teams.[47] The campaign was called the Ouse to Ouse Tock in Krio language.[48] There was concern the 72-hour lock-down could backfire.[49]
Quarantine travel pass, Sierra Leone
On 22 September, Stephen Gaojia said that the three-day lock down had obtained its objective and would not be extended. Eighty percent of targeted households were reached in the operation. A total of around 150 new cases were uncovered, but the exact figures would only be known on the following Thursday as the health ministry was still awaiting reports from remote locations.[50] One incident during the lock-down was when a burial team was attacked.[51]
On 24 September, President Ernest Bai Koroma added three more districts under "isolation", in an effort to contain the spread. The districts included Port Loko, Bombali, and Moyamba. In the capital, Freetown, all homes with identified cases would be quarantined. This brought the total areas under isolation to 5, including the outbreak "hot spots" Kenema and Kailahun which were already in isolation. Only deliveries and essential services would be allowed in and out. A sharp rise in cases in these areas was also noted by WHO.[52]
As of late September, about 2 million people were in areas of restricted travel,[53] which included Kailahun, Kenema, Bombali, Tonkolili, and Port Loko Districts.[54] The number of cases seemed to be doubling every 20 days, which led to the estimate that by January 2015 the number of cases in Liberia and Sierra Leone could grow to 1.4 million.[55]
On 25 September, there were 1940 cases and 587 deaths officially, however, many acknowledged under-reporting and there was an increasing number of cases in Freetown (the capital of Sierra Leone).[56]
WHO estimated on 21 September, that Sierra Leone's capacity to treat Ebola cases fell short by the equivalent of 532 beds.[44] There were reports that political interference and administrative incompetence had hindered the flow of medical supplies into the country.[57]
By 2 October 2014, an estimated 5 people per hour were being infected with the Ebola virus in Sierra Leone.[58] By this time it was estimated the number of infected had been doubling every 20 days.[59] On 4 October, Sierra Leone recorded 121 fatalities, the largest number in a single day.[60] On 8 October, Sierra Leone burial crews went on strike.[61] On 12 October, it was reported that the UK would begin providing military support to Sierra Leone in addition to a major UK civilian operation in support of the Government of Sierra Leone.[62]
In October, it was noted hospitals were running out of supplies in Sierra Leone.[63] There were reports that political interference and administrative incompetence hindered the flow of medical supplies into the country.[57] In the week prior to 2 October there were 765 new cases, and Ebola was spreading rapidly.[64] At the start of October, there were nearly 2200 laboratory confirmed cases of Ebola and over 600 had died from it.[65] The epidemic also had claimed the life of 4 doctors and at least 60 nurses by the end of September 2014.[66] Sierra Leone limited its reported deaths to laboratory confirmed cases in facilities, so the actual number of losses was known to be higher.[11]
Sierra Leone was considering making reduced care clinics, to stop those sick with Ebola from getting their families sick with the disease and to provide something in between home-care and the full-care clinics.[67] These "isolation centers" would provide an alternative to the overwhelmed clinics.[67] The problem the country was facing was 726 new Ebola cases but less than 330 beds available.[68]
More than 160 additional medical personnel from Cuba arrived in early October, building on about 60 that had been there since September.[69] At that time there were about 327 beds for patients in Sierra Leone.[70] Canada announced it was sending a 2nd mobile lab and more staff to Sierra Leone on 4 October 2014.[71]
There were reports of drunken grave-diggers making graves for Ebola patients too shallow, and as a result wildlife came and dug up and ate at the corpses.[72] In addition, in some cases bodies were not buried for days, because no one came to collect them.[73] One problem was that it was hard to care for local health care workers, and there was not enough money to evacuate them.[74] Meanwhile, other diseases like malaria, pneumonia, and diarrhea were not being treated properly because the health system was trying to deal with Ebola patients.[75] On 7 October 2014, Canada sent a C-130 loaded with 128,000 face shields to Freetown.[76]
In early October 2014, a burial team leader said there were piles of corpses south of Freetown.[77] On 9 October, the International Charter on Space and Major Disasters was activated on Sierra Leone's behalf, the first time that its charitably repurposed satellite imaging assets had been deployed in an epidemiological role.[78][79] On 14 October 2014, 800 Sierra Leone peacekeepers due to relieve a contingent deployed in Somalia, were placed under quarantine when one of the soldiers tested positive for Ebola.[80]
The last district in Sierra Leone untouched by the Ebola virus declared Ebola cases. According to Abdul Sesay, a local health official, 15 suspected deaths with 2 confirmed cases of the deadly disease were reported on 16 October, in the village of Fakonya. The village is 60 miles from the town of Kabala in the center of the mountainous region of the Koinadugu district. This was the last district free from the virus in Sierra Leone. All of the districts in this country had then confirmed cases of Ebola.[81]
The Royal Navy's Argus
In late October 2014, the United Kingdom sent one of their hospital ships, the Royal Navy's Argus, to help Sierra Leone.[82] By late October Sierra Leone was experiencing more than twenty deaths a day from Ebola.[83] In October 2014, officials reported that very few pregnant women were surviving Ebola disease.[84] In previous outbreaks pregnant women were noted to have a higher rate of death with Ebola.[85]
Officials struggled to maintain order in one town after a medical team trying to take a blood sample from a corpse were blocked by an angry machete-wielding mob. They allegedly believed the person had died from high-blood pressure and did not want the body being tested for Ebola. When security forces tried to defend the medical team, a riot ensued leaving two dead. The town was placed on a 24-hour curfew and authorities tried to calm the situation down.[86] Despite this several buildings were attacked.[87]
On 30 October, the ship Argus arrived in Sierra Leone.[88] It carried 32 off-road vehicles to support Ebola treatment units.[89] The ship also carried three transport helicopters to support operations against the epidemic.[90] By the end of October 2014 there were over 5200 laboratory confirmed cases of Ebola virus disease in Sierra Leone.[citation needed]

On 31 October 2014, an ambulance driver in Bo District died of Ebola. His ambulance picked up Ebola patients (or suspected Ebola cases) and took them to treatment centers.[92]
November 2014: Continuing struggle
On 1 November, the United Kingdom announced plans to build three more Ebola laboratories in Sierra Leone. The labs helped to determine if a patient had been infected by the Ebola virus. At that time, it took as much as five days to test a sample because of the volume of samples that needed to be tested.[93]
On 2 November, a person with Ebola employed by the United Nations was evacuated from Sierra Leone to France for treatment. On 4 November, it was reported that thousands violated quarantine in search for food, in the town of Kenema.[94] On 6 November, it was reported that the situation was "getting worse" due to "intense transmission" in Freetown as a contributing factor; the capital city reported 115 cases in the previous week alone. Food shortages and aggressive quarantines were reported to be making the situation worse, according to the Disaster Emergency Committee.[95] Sierra Leone established call centers in Port Loko and Kambia, according to MSSL Communications as reported on 21 November;[96] this was in addition to the June hotline originally established.[97]
On 12 November, more than 400 health workers went on strike over salary issues at one of the few Ebola treatment centers in the country.[98] On 18 November, the supply ship Karel Doorman of the Royal Netherlands Navy (Koninklijke Marine) arrived in Freetown, with supplies. Its Captain-Commander, Peter van den Berg, took steps to reduce the chance of the crew contracting Ebola virus disease.[99]
The Neini Chiefdom in Koinadugu District was subject to isolation after Ebola cases.[100] On 19 November, it was reported that the Ebola virus was spreading intensely; "much of this was driven by intense transmission in the country's west and north", the WHO said.[101]
Ebola treatment centre built by the UK in Kerry Town in 2014
A British-built Ebola Treatment Centre which started in Kerry Town during November, generated some controversy because of its initially limited capacity. However, this was because they were following guidelines of how to safely open an Ebola treatment unit. This was the first of six planned treatment centres which, when completed, would be staffed by a number of NGOs.[102]
In mid-November the WHO reported that while all cases and deaths continued to be under-reported, "there is some evidence that case incidence is no longer increasing nationally in Guinea and Liberia, but steep increases persist in Sierra Leone".[103] On 19 November, it was reported that the Ebola virus was spreading intensely; "much of this was driven by intense transmission in the country's west and north", the WHO said.[101] The first Cuban doctor to be infected with the virus was flown to Geneva.[104] On 26 November, it was reported that due to Sierra Leone's increased Ebola transmission, the country would surpass Liberia in the total cases count.[105] On 27 November, Canada announced it would deploy military health staff to the infected region.[106] On 29 November, the President of Sierra Leone canceled a planned three-day shutdown in Freetown to curb the virus.[107]
December 2014
A situation map of Sierra Leone and surrounding nations showing the districts with reported cases of Ebola, as of 17 December 2014
On 2 December, it was reported that the Tonkolili district had begun a two-week lockdown, "which was agreed in a key stakeholders meeting of cabinet ministers, parliamentarians and paramount chiefs of the district as part of efforts to stem the spread of the disease", according to a ministry spokesman. The move meant that a total of six districts, containing more than half of the population, were locked down.[108]
Sierra Leone indicated, in a report on 5 December, that about 100 cases of the virus were now being reported daily.[109] On the same day, it was further reported that families caught taking part in burial washing rituals, which can spread the virus, would be taken to jail.[110] On 6 December, a report indicated that the Canadian Armed Forces would send a medical team to the country of Sierra Leone to help combat the Ebola virus epidemic.[111]
On 8 December, the doctors in Sierra Leone went on strike, demanding better treatment for health care workers, according to Health Ministry spokesman Jonathan Abass Kamara.[112]
On 9 December, Sierra Leone authorities placed the Eastern Kono District in a two-week lock-down following the alarming rate of infection and deaths there. The lock down lasted until 23 December.[113] This followed the grim discovery of bodies piling up in the district. The WHO reported fear of a major breakout in the area. The district with 350,000 inhabitants buried 87 bodies in 11 days, with 25 patients dying in 5 days before the WHO arrived.[114]
On 12 December, Sierra Leone banned all public festivities for Christmas or New Year, because of the outbreak.[115] On 13 December, it was reported that the first Australian facility had been opened; "operations will be gradually scaled up to full capacity at 100 beds under strict guidelines to ensure infection control procedures are working effectively and trained staff... are in place", one source indicated.[116]
Médecins Sans Frontières/Doctors Without Borders, in partnership with the Ministry of Health, carried out during December the largest-ever distribution of antimalarials in Sierra Leone. Teams distributed 1.5 million antimalarial treatments in Freetown and surrounding districts with the aim of protecting people from malaria during the disease's peak season. A spokesman said "In the context of Ebola, malaria is a major concern, because people who are sick with malaria have the same symptoms as people sick with Ebola. As a result, most people turn up at Ebola treatment centres thinking that they have Ebola, when actually they have malaria. It's a huge load on the system, as well as being a huge stress on patients and their families."[117]
Between 14 and 17 December Sierra Leone reported 403 new cases with a total of 8,759 cases on the latter date.[118][119] On 25 December, Sierra Leone put the north area of the country on lockdown.[120] By the end of December Sierra Leone again reported a surge in numbers, with 9,446 cases reported.[121][122]
On 4 January, the lockdown was extended for two weeks.[125] On this day the country reported 9780 cases with 2943 deaths. Among healthcare workers there were 296 cases with 221 fatalities reported.[126]
On 8 January, MSF admitted its first patients to a Treatment Centre (ETC) in Kissy, an Ebola hotspot on the outskirts of Freetown. Once the ETC is fully operational it will include specialist facilities for pregnant women.[127] By 9 January, the case load in the country exceeded 10,000, with 10,074 cases and 3,029 deaths reported.[128] On 9 January, it was reported that South Korea would send a medical team to Goderich.[129]
On 10 January, Sierra Leone declared its first Ebola-free district. The Pujehun district in the south east of the country reported no new cases for 42 days.[130]
February 2015
A worker at Kerry Town clinic was evacuated to the United Kingdom on 2 February 2015, after a needlestick injury.[131] On 5 February, it was reported that there was a rise in weekly cases for the first time this year.[132][133] The U.N. indicated that the sharp drop in cases had "flattened out" raising concern about the virus.[134]
March 2015
Port Loko District Ebola Response Centre staff remove contaminated items in April 2015.
On 5 March, a report indicated cases in Sierra Leone continued to rise.[135] The government of Sierra Leone declared a three-day country-wide lock-down including 2.5 million people on 18 March.[136][137] The U.N. indicates the outbreak will be over by August of this year.[138]
The 3-day lock-down of over 6 million inhabitants revealed a 191% increase in possible Ebola cases. In Freetown alone 173 patients meeting the criteria for Ebola were discovered according to Obi Sesay from the National Ebola Response Center.[139]
Spring 2015
As of 12 May, Sierra Leone had gone 8 days without an Ebola case, and was down to two confirmed cases of Ebola.[140] The WHO weekly update for 29 July reported a total of only three new cases, the lowest total in more than a year.[141] On 17 August, the country had its first week with no new cases,[142] and one week later the last patients were released.[143]
August/September 2015
A new death was reported on 1 September after a patient from Sella Kafta village in Kambia District was tested positive for the disease after her death.[144] On 5 September, another case of Ebola was identified in the village among the approximately 1000 people currently under quarantine. A woman tested positive for the virus. The "Guinea ring vaccine" has been administered by a WHO team in the village since Friday 5 September.[145] On 8 September the head of the National Ebola Response Center confirmed new cases of Ebola. This brought the total from the village to four cases, with all of them being under the "high risk" contact cases with the death of the new index case in the village. In total four cases were then confirmed including the dead woman.[146]
On 14 September, the National Ebola Response Center confirmed the death of a 16-year-old in a village in the Bombali district. Swabs taken from the body tested positive for the disease. The village was placed under quarantine.[147] She had no history of traveling outside the village, and it is suspected that she contracted the disease from the semen of an Ebola survivor who was discharged in March 2015. Seven of her immediate contacts were taken to an Ebola treatment center, with a further three patients she had contact with at a health clinic.[148] A new study to be published in the New England Journal of Medicine indicates the possibility that the virus may lurk in the semen of survivors for up to six months. Nearly half of 200 patients tested had traces of the virus in their semen six months after surviving the disease.[149] On 7 November, the World Health Organization declared Sierra Leone Ebola-free.[150]
January 2016
Sierra Leone entered a 90-day period of enhanced surveillance which was scheduled to conclude on 5 February 2016, but due to a new case in mid-January it did not.[151] On 14 January, it was reported there had been a fatality linked to the Ebola virus. The case occurred in the Tonkolili district.[152] Prior to this case WHO had advised, "we anticipate more flare-ups and must be prepared for them... massive effort is underway to ensure robust prevention, surveillance and response capacity across all three countries by the end of March."[153] On 16 January, it was reported that the woman who died of the virus may have exposed several individuals; the government announced that 100 people had been quarantined.[154] On the same day, WHO released a statement, indicating that originally the 90-day enhanced surveillance period was to end on 5 February. Investigations indicate the female case was a student at Lunsar in Port Loko district, who had gone to Kambia district on 28 December until returning symptomatic. Bombali district was visited by the individual, for consultation with an herbalist, later going to a government hospital in Magburaka. WHO indicates there are 109 contacts, 28 of which are high risk, furthermore, there are three missing contacts.The source or route of transmission which caused the fatality is still unknown.[155] A second new case was confirmed on 20 January; the patient had contact with the previous fatality.[156] On 17 March, the WHO declared the country Ebola-free.[157]
Healthcare capacity
Long-term political factors contributed to the Ebola crisis including the acute dependency on external health assistance, patron-client politics, corruption and a weak state capacity.[158] Prior to the Ebola epidemic Sierra Leone had about 136 doctors and 1,017 nurses/midwives for a population of about 6 million people.[159] On 26 August, the WHO (World Health Organisation) shut down one of two laboratories after a health worker became infected. The laboratory was situated in the Kailahun district, one of the worst-affected areas. It was thought by some that this move would disrupt efforts to increase the global response to the outbreak of the disease in the district.[160]
"It's a temporary measure to take care of the welfare of our remaining workers", WHO spokesperson Christy Feig announced. He did not specify how long the closure would last, but said they would return after an assessment of the situation by the WHO. The medical worker, one of the first WHO staff infected by the Ebola Virus, was treated at a hospital in Kenema and then evacuated to Germany.[160][161] By 4 October 2014, it was announced he has recovered and left Germany.[162]
As the Ebola epidemic grew it damaged the health care infrastructure, leading to increased deaths from other health issues including malaria, diarrhoea, and pneumonia because they were not being treated.[163] The WHO estimated on 21 September that Sierra Leone's capacity to treat Ebola cases fell short by the equivalent of 532 beds.[44]
On 27 August 2014, Dr. Sahr Rogers died from Ebola after contracting it working in Kenema.[165] Sierra Leone lost three of its top doctors by the end of August to Ebola.[166]
A fourth doctor, Dr. Olivette Buck, became ill with Ebola in September and died later that month.[167] Dr. Olivette Buck was a Sierra Leone doctor who worked in Freetown, who tested positive for Ebola on 9 September 2014, and died on 14 September 2014.[41] Her staff believes she was exposed in August. She eventually went to Lumley Hospital on 1 September 2014, with a fever, thinking it was malaria.[41] After a few more days of illness she was admitted to Connaught Hospital.[41]
By 23 September 2014, out of 91 health workers known to have been infected with Ebola in Sierra Leone, approximately 61 had died.[168]
On 19 October, the WHO reported 129 cases with 95 deaths of healthcare workers (125 / 91 confirmed).[169] On 2 November 2014, a fifth doctor, Dr. Godfrey George, a medical superintendent of Kambia Government Hospital died as a result of Ebola infection.[170] On 17 November 2014, a sixth doctor, Dr Martin Salia, died as a result of Ebola infection, after being transported by medevac to Nebraska Medical Center in the United States.[171]
Dr. Aiah Solomon Konoyeima was reported to have Ebola in late November 2014, which would make him the eighth physician to contract Ebola.[173] He was reported to have died from the disease on 7 December 2014, becoming what was reported as the tenth doctor to die from Ebola.[174]
On 26 November 2014, a ninth doctor, Dr. Songo Mbriwa, was reported to be sick with Ebola disease.[175] He was working at an Ebola treatment centre in Freetown.[175] He was one of the doctors that cared for the late Dr Martin Salia, who experienced a false-negative Ebola test, but did indeed have it and may have exposed others.[176]
On Friday 5 December, a senior health official announced the death of two of the country's doctors in one day. This brings the total number of doctors who have died from the disease in Sierra Leone to ten. Dr Dauda Koroma and Dr Thomas Rogers are the latest deaths among healthcare workers.[177] The two doctors were not in the front line of the Ebola battle and did not work in an Ebola treatment hospital.[178]
On 18 December, Dr. Victor Willoughby died from the disease after being tested positive for the disease on Saturday 6 December. The doctor died hours before he was to receive ZMAb, an experimental treatment from Canada, according to Dr. Brima Kargbo the country's chief medical officer. Dr. Victor Willoughby is the 11th doctor, and a top physician, to succumb to the disease.[179]
Evacuations
Since the beginning of the outbreak in Sierra Leone in late May 2014, several people have been evacuated. An increasing lack of hospital beds, medical equipment, and health care personnel made treatment difficult.[citation needed]On 24 August William Pooley, a British nurse, was evacuated from Sierra Leone. He was released on 3 September 2014.[180][181] In October 2014, he announced he would return to Sierra Leone.[182]
On 21 September 2014, Spain evacuated a Catholic priest who had contracted Ebola while working in Sierra Leone with Hospital Order of San Juan de Dios.[183] He died on 25 September in Madrid.[184] On 6 October 2014, a nurse who treated the priest tested positive for Ebola.[185] By 20 October 2014, the nurse seemed to have recovered after many days battling the disease in the hospital, with tests coming back negative.[186]
A doctor from Senegal contracted Ebola while working in Sierra Leone for the WHO, and was evacuated to Germany at the end of August 2014.[187] By 4 October 2014, it was announced he has recovered and returned to Senegal.[162]
In late September, a doctor working for an International Aid organization in Sierra Leone, was evacuated to Switzerland after potentially being exposed. He later tested negative for the disease.[188]
In late September 2014, an American doctor working in Sierra Leone was evacuated to Maryland, USA, after being exposed to Ebola.[189] "Just because someone is exposed to the deadly virus, it doesn't necessarily mean they are infected", said Anthony S. Fauci, director of the National Institute of Allergy and Infectious Diseases at the NIH.[189] He was evacuated after a needle sticking accident and even developed a fever, but he was determined not to have Ebola and was released the first week in October 2014. After being discharged he remained at home under medical observation, checking his temperature twice a day for 21 days.[190]
In early October, a Ugandan doctor who contracted Ebola while working in Sierra Leone was evacuated for treatment to Frankfurt, Germany.[191] The doctor was working at Lakaa Hospital and flown out from Lungi Airport.[192]
On 6 October 2014, a female Norwegian MSF worker tested positive for Ebola virus and was subsequently evacuated to Norway.[193] Norwegian authorities reported that they had been granted a dose of the experimental biopharmaceutical drug ZMAb, a variant of ZMapp.[194][195][196] ZMapp has previously been used on 3 Liberian health workers, of which 2 survived.[197] It was also used on 4 evacuated westerners, of which 3 survived.[198][199][200][201][202][203] A U.N. employee was evacuated to France in early November 2014 after contracting Ebola.[204]
On 12 November 2014, Dr Martin Salia, a permanent resident of the United States, tested positive for Ebola while working as a specialist surgeon at the Connaught Hospital in Freetown. He is the sixth Sierra Leone doctor to have contracted Ebola virus disease. Initially he preferred to be treated at the Hastings Holding Centre by Sierra Leonean medical personnel, however on 15 November 2014, he was evacuated to the Nebraska Medical Center where his condition was reported as "still extremely critical" on 16 November.[205][206][207] On 16 November the hospital released a statement that he "passed away as a result of the advanced symptoms of the disease".[171]
On 18 November a Cuban doctor, Felix Baez, tested positive for Ebola and was due to be sent to Geneva for treatment. He later recovered. Baez was one of 165 Cuban doctors and nurses in Sierra Leone helping treat Ebola patients. There were a further 53 Cubans in Liberia and 38 in Guinea, making this the largest single country medical team mobilized during the outbreak.[208][209]
Confounding factors
Freetown, Sierra Leone
Sierra Leonean government intransigence
On 5 October, The New York Times reported that a shipping container full of protective gowns, gloves, stretchers, mattresses and other medical supplies had been allowed to sit unopened on the docks in Freetown, Sierra Leone, since 9 August.[210] The $140,000 worth of equipment included 100 bags and boxes of hospital linens, 100 cases of protective suits, 80 cases of face masks and other items, and were donated by individuals and institutions in the United States.[210]
The shipment was organised by Mr Chernoh Alpha Bah, a Sierra Leonean opposition politician, who comes from Sierra Leonean President Ernest Bai Koroma's hometown, Makeni.[210]The New York Times reported that political tensions may have contributed to the government delay in clearing the shipping container, to prevent the political opposition from trumpeting the donations.[210]
Government officials stated that the shipping container could not be cleared through customs, as proper procedures had not been followed.[210] The Sierra Leonean government refused to pay the shipping fee of $6,500.[210]The New York Times noted that the government had already received well over $40 million in cash from international donors to fight Ebola.[210]The New York Times noted that in the 2 months that the shipping container remained on the docks in Freetown, health workers in Sierra Leone endured severe shortages of protective supplies, with some nurses having to wear street clothes.[210]
David Tam-Baryoh, a radio journalist, was held for 11 days when he and a talk show guest, an opposition party spokesperson, criticised how President Ernest Bai Koroma handled the Ebola outbreak in a live broadcast on 1 November 2014. The weekly show Monologue was taken off-air mid-show from the independently run Citizen FM.[211] He was arrested on 3 November and sent to the Pademba Road jail, after an executive order was signed by the president. On 14 November Sierra Leone's Deputy Information Minister Theo Nicol gave a statement that Baryoh had "been put on a ten thousand dollar bail by the Criminal Investigation Department after a statement has been taken from him".[212]
Amid concerns for his health, Tam-Baryoh apparently signed a confession to ensure his release from the prison, engineered by a committee made up of his lawyer, 2 journalists and a peace studieslecturer of the University of Sierra Leone. Rightsway International, an independent human rights group, has condemned President Koroma for allegedly dictating to the committee about obtaining the confession. A statement later released by the group read:[213]
Rightsway is disappointed that Tam Baryoh's forced confession has been published widely by pro-government media outlets and social networks. The publication of forced confessions is often used to discredit dissident news and information providers. This is a media propaganda tool used by dictatorial regimes, to avoid being exposed, investigated and punished for the grave violations of human rights.
Local conspiracy theories
"The Ebola outbreak was sparked by a bewitched aircraft that crashed in a remote part of Sierra Leone, casting a spell over three West African countries – but a heavily alcoholic drink called bitter Kola can cure the virus."[214]
"Some members of the community thought it was a bad spirit, a devil or poisoning."[215]
At the beginning of the outbreak, many did not believe that the disease existed. "I thought it was a lie (invented) to collect money because at that moment I hadn't seen people affected in my community."[215]
Community violence
On 21 October, there was Ebola related violence and rioting in the eastern town of Koidu, with police imposing a curfew.[216] Local youth fired at police with shotguns after a former youth leader refused health authorities permission to take her relative for an Ebola test.[216] Several buildings were attacked and youth gangs roamed the streets shouting "No more Ebola!"[217]
A local leader reported seeing two bodies with gunshot wounds in the aftermath. Police denied that anyone had been killed.[216] Doctors reported two dead.[217] The local district medical officer said he had been forced to abandon the local hospital because of the rioting.[216]

Additional effects
Hand-washing station at Lungi Airport
The outbreak was noted for increasing hand washing stations, and reducing the prevalence of physical greetings such as hand-shakes between members of society.[234]
In June 2014 all schools were closed because of the spread of Ebola.[235]
In August 2014 the S.L. Health Minister was removed from that office.[236] (see Cabinet of Sierra Leone) In October 2014 the Defense Minister was placed in charge of the anti-Ebola efforts.[237] The president at this time was Ernest Bai Koroma.[237]

In August 2014, George Weah and Ghanaian musician Sidney produced a song to raise awareness about Ebola.[247] All proceeds from the track been donated to the Liberian Health Ministry.[248]
There are a number of Ebola-themed jokes circulating in West Africa to spread awareness.[249]
Guinea faces a number of ongoing health challenges.
As of 24 September 2012, a cholera outbreak in Sierra Leone had caused the deaths of 392 people. It was the country's largest outbreak of cholera since first reported in 1970 and the deadliest since the 1994–1995 cholera outbreak. The outbreak has also affected Guinea, which shares a reservoir near the coast. This was the largest cholera outbreak in Africa in 2012.
Ebola, also known as Ebola virus disease (EVD) and Ebola hemorrhagic fever (EHF), is a viral hemorrhagic fever in humans and other primates, caused by ebolaviruses. Symptoms typically start anywhere between two days and three weeks after infection. The first symptoms are usually fever, sore throat, muscle pain, and headaches. These are usually followed by vomiting, diarrhoea, rash and decreased liver and kidney function, at which point some people begin to bleed both internally and externally. It kills between 25% and 90% of those infected – about 50% on average. Death is often due to shock from fluid loss, and typically occurs between six and 16 days after the first symptoms appear. Early treatment of symptoms increases the survival rate considerably compared to late start. An Ebola vaccine was approved by the US FDA in December 2019.
The 2013–2016 epidemic of Ebola virus disease, centered in West Africa, was the most widespread outbreak of the disease in history. It caused major loss of life and socioeconomic disruption in the region, mainly in Guinea, Liberia and Sierra Leone. The first cases were recorded in Guinea in December 2013; the disease spread to neighbouring Liberia and Sierra Leone, with minor outbreaks occurring in Nigeria and Mali. Secondary infections of medical workers occurred in the United States and Spain. Isolated cases were recorded in Senegal, the United Kingdom and Italy. The number of cases peaked in October 2014 and then began to decline gradually, following the commitment of substantial international resources.
An epidemic of Ebola virus disease in Guinea from 2013 to 2016 represented the first-ever outbreak of Ebola in a West African country. Previous outbreaks had been confined to several countries in Sub-Saharan Africa.
An epidemic of Ebola virus disease occurred in Liberia from 2014 to 2016, along with the neighbouring countries of Guinea and Sierra Leone. The first cases of virus were reported by late March 2014. The Ebola virus, a biosafety level four pathogen, is an RNA virus discovered in 1976.
Four laboratory-confirmed cases of Ebola virus disease occurred in the United States in 2014. Eleven cases were reported, including these four cases and seven cases medically evacuated from other countries. The first was reported in September 2014. Nine of the people contracted the disease outside the US and traveled into the country, either as regular airline passengers or as medical evacuees; of those nine, two died. Two people contracted Ebola in the United States. Both were nurses who treated an Ebola patient; both recovered.
Organizations from around the world responded to the West African Ebola virus epidemic. In July 2014, the World Health Organization (WHO) convened an emergency meeting with health ministers from eleven countries and announced collaboration on a strategy to co-ordinate technical support to combat the epidemic. In August, they declared the outbreak an international public health emergency and published a roadmap to guide and coordinate the international response to the outbreak, aiming to stop ongoing Ebola transmission worldwide within 6–9 months. In September, the United Nations Security Council declared the Ebola virus outbreak in the West Africa subregion a "threat to international peace and security" and unanimously adopted a resolution urging UN member states to provide more resources to fight the outbreak; the WHO stated that the cost for combating the epidemic will be a minimum of $1 billion.
In 2014, Ebola virus disease in Spain occurred due to two patients with cases of the disease contracted during the Ebola virus epidemic in West Africa; they were medically evacuated. A failure in infection control in the treatment of the second patient led to an isolated infection of Ebola virus disease in a health worker in Spain itself. The health worker survived her Ebola infection, and has since been declared infection-free.
This article covers the timeline of the 2014 Ebola virus epidemic in West Africa and its outbreaks elsewhere. Flag icons denote the first announcements of confirmed cases by the respective nation-states, their first deaths, and their first secondary transmissions, as well as relevant sessions and announcements of agencies such as the World Health Organization (WHO), the U.S. Centers for Disease Control (CDC), and NGOs such as Doctors Without Borders; medical evacuations, visa restrictions, border closures, quarantines, court rulings, and possible cases of zoonosis are also included.
Ebola virus disease in Mali occurred in October 2014, leading to concern about the possibility of an outbreak of Ebola in Mali. A child was brought from Guinea and died in the northwestern city of Kayes. Mali contact traced over 100 people who had contact with the child; tracing was completed in mid-November with no further cases discovered. In November, a second unrelated outbreak occurred in Mali's capital city, Bamako. Several people at a clinic are thought to have been infected by a man traveling from Guinea. On January 18, Mali was declared Ebola-free after 42 days with no new cases. There had been a cumulative total of eight cases with six deaths.
The following lists events that happened during 2014 in Sierra Leone.
The Ebola virus epidemic in West Africa has had a large effect on the culture of most of the West African countries. In most instances, the effect is a rather negative one as it has disrupted many Africans’ traditional norms and practices. For instance, many West African communities rely on traditional healers and witch doctors, who use herbal remedies, massage, chant and witchcraft to cure just about any ailment. Therefore, it is difficult for West Africans to adapt to foreign medical practices. Specifically, West African resistance to Western medicine is prominent in the region, which calls for severe distrust of Western and modern medical personnel and practices.(see Ebola conspiracies below.)
Ebola virus disease in the United Kingdom and Ireland has occurred rarely in four cases to date, namely three health workers returning from treating victims of the Ebola virus epidemic in West Africa in 2014 and 2015, and a single case in 1976, when a laboratory technician contracted the disease in a needlestick injury while handling samples from Africa. All cases recovered. As of 2023, no domestic transmission of Ebola has occurred in the United Kingdom or Ireland.
In late October 2014, the United Kingdom sent a hospital ship, the Royal Fleet Auxiliary's Argus, to help the aid effort against the Ebola virus disease epidemic in Sierra Leone. By late October Sierra Leone was experiencing more than twenty deaths a day from Ebola.
Cases of the Ebola virus disease in Nigeria were reported in 2014 as a small part of the epidemic of Ebola virus disease which originated in Guinea that represented the first outbreak of the disease in a West African country. Previous outbreaks had been confined to countries in Central Africa.
There is a cure for the Ebola virus disease that is currently approved for market the US government has inventory in the Strategic National Stockpile. For past and current Ebola epidemics, treatment has been primarily supportive in nature.
Post-Ebola virus syndrome is a post-viral syndrome affecting those who have recovered from infection with Ebola. Symptoms include joint and muscle pain, eye problems, including blindness, various neurological problems, and other ailments, sometimes so severe that the person is unable to work. Although similar symptoms had been reported following previous outbreaks in the last 20 years, health professionals began using the term in 2014 when referring to a constellation of symptoms seen in people who had recovered from an acute attack of Ebola disease.
In March 2014, the World Health Organization (WHO) reported a major Ebola outbreak in Guinea, a western African nation, the disease then rapidly spread to the neighboring countries of Liberia and Sierra Leone with smaller outbreaks occurring in Senegal, Nigeria, and Mali; the resulting West African Ebola virus epidemic is the largest Ebola outbreak ever documented.
