Mpox is an infectious viral disease that can occur in humans and some other animals. Symptoms include a rash that forms blisters and then crusts over, fever, and swollen lymph nodes. The illness is usually mild and most of those infected will recover within a few weeks without treatment. The time from exposure to onset of symptoms ranges from five to twenty-one days and symptoms typically last from two to four weeks. Cases may be severe, especially in children, pregnant women or people with suppressed immune systems.
Polio eradication, the permanent global cessation of circulation of the poliovirus and hence elimination of the poliomyelitis (polio) it causes, is the aim of a multinational public health effort begun in 1988, led by the World Health Organization (WHO), the United Nations Children's Fund (UNICEF) and the Rotary Foundation. These organizations, along with the U.S. Centers for Disease Control and Prevention (CDC) and The Gates Foundation, have spearheaded the campaign through the Global Polio Eradication Initiative (GPEI). Successful eradication of infectious diseases has been achieved twice before, with smallpox in humans and rinderpest in ruminants.
The 2008 Zimbabwean cholera outbreak was an epidemic of cholera affecting much of Zimbabwe from August 2008 until June 2009. The outbreak began in Chitungwiza in Harare Metropolitan Province in August 2008, then spread throughout the country so that by December 2008, cases were being reported in all 10 provinces. In December 2008, The Zimbabwean government declared the outbreak a national emergency and requested international aid. The outbreak peaked in January 2009 with 8,500 cases reported per week. Cholera cases from this outbreak were also reported in neighboring countries South Africa, Malawi, Botswana, Mozambique, and Zambia. With the help of international agencies, the outbreak was controlled, and by July 2009, after no cases had been reported for several weeks, the Zimbabwe Ministry of Health and Child Welfare declared the outbreak over. In total, 98,596 cases of cholera and 4,369 deaths were reported, making this the largest outbreak of cholera ever recorded in Zimbabwe. The large scale and severity of the outbreak has been attributed to poor sanitation, limited access to healthcare, and insufficient healthcare infrastructure throughout Zimbabwe.
Health problems have been a long-standing issue limiting development in the Democratic Republic of the Congo.
The 2009–2010 West African meningitis outbreak was an epidemic of bacterial meningitis which occurred in Burkina Faso, Mali, Niger, and Nigeria since January 2009, an annual risk in the African meningitis belt. A total of 13,516 people have been infected with meningitis, and 931 have died. Nigeria has been the most adversely affected, with over half of the total cases and deaths occurring in the nation. The WHO reported on 27 March 2009 that 1,100 had died and there were 25,000 suspected cases. It is the worst outbreak in the region since 1996, and a third of the world's emergency vaccine stockpile for the bacterial form has been consumed. The GAVI Alliance has been trying to secure more vaccines.
Seven cholera pandemics have occurred in the past 200 years, with the first pandemic originating in India in 1817. The seventh cholera pandemic is officially a current pandemic and has been ongoing since 1961, according to a World Health Organization factsheet in March 2022. Additionally, there have been many documented major local cholera outbreaks, such as a 1991–1994 outbreak in South America and, more recently, the 2016–2021 Yemen cholera outbreak.
Bas-Uélé is one of the 21 new provinces of the Democratic Republic of the Congo created in the 2015 repartitioning. Bas-Uélé, Haut-Uélé, Ituri, and Tshopo provinces are the result of the dismemberment of the former Orientale Province. Bas-Uélé was formed from the Bas-Uele District whose town of Buta was elevated to capital city of the new province.
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 Western 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; later, 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. In addition, 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.
In 2014, an outbreak of Ebola virus disease in the Democratic Republic of the Congo (DRC) occurred. Genome sequencing has shown that this outbreak was not related to the 2014–15 West Africa Ebola virus epidemic, but was of the same EBOV species. It began in August 2014 and was declared over in November of that year, after 42 days without any new cases. This is the 7th outbreak there, three of which occurred during the period of Zaire.
The Democratic Republic of the Congo (DRC) was identified by the World Health Organization (WHO) on 11 May 2017 as having one Ebola-related death.
An outbreak of cholera began in Yemen in October 2016. The outbreak peaked in 2017 with over 2,000 reported deaths in that year alone. In 2017 and 2019, war-torn Yemen accounted for 84% and 93% of all cholera cases in the world, with children constituting the majority of reported cases. As of November 2021, there have been more than 2.5 million cases reported, and more than 4,000 people have died in the Yemen cholera outbreak, which the United Nations deemed the worst humanitarian crisis in the world at that time. However, the outbreak has substantially decreased by 2021, with a successful vaccination program implemented and only 5,676 suspected cases with two deaths reported between January 1 and March 6 of 2021.
The 2018 Équateur province Ebola outbreak occurred in the north-west of the Democratic Republic of the Congo (DRC) from May to July 2018. It was contained entirely within Équateur province, and was the first time that vaccination with the rVSV-ZEBOV Ebola vaccine had been attempted in the early stages of an Ebola outbreak, with a total of 3,481 people vaccinated. It was the ninth recorded Ebola outbreak in the DRC.
The Kivu Ebola epidemic was an outbreak of Ebola virus disease (EVD) mainly in eastern Democratic Republic of the Congo (DRC), and in other parts of Central Africa, from 2018 to 2020. Between 1 August 2018 and 25 June 2020 it resulted in 3,470 reported cases. The Kivu outbreak also affected Ituri Province, whose first case was confirmed on 13 August 2018. In November 2018, the outbreak became the biggest Ebola outbreak in the DRC's history, and had become the second-largest Ebola outbreak in recorded history worldwide, behind only the 2013–2016 Western Africa epidemic. In June 2019, the virus reached Uganda, having infected a 5-year-old Congolese boy who entered Uganda with his family, but was contained.
In 2019, a measles epidemic broke out in the Democratic Republic of the Congo (DRC). The epidemic started in early 2019 in the southeast corner of the DRC and then spread to all provinces. By June 2019 the epidemic was reported to have exceeded the death toll of the concurrent Ebola epidemic. By April 2020, it had infected more than 341,000 people and claimed about 6,400 fatalities. This has primarily affected children under the age of five, representing 74% of infections and nearly 90% of deaths.
On 7 February 2021, the Congolese health ministry announced that a new case of Ebola near Butembo, North Kivu had been detected the previous day. The case was a 42-year-old woman who had symptoms of Ebola in Biena on 1 February 2021. A few days after, she died in a hospital in Butembo. The WHO said that more than 70 people who had contact with the woman had been tracked.
In 2021, Niger has been affected by subsequent floods due to heavy rains, causing several deaths and widespread damage nationwide. Niamey is the most affected area.
