The 2009 swine flu pandemic was confirmed to have spread to the Philippines on May 21, 2009. In the following days, several local cases were reported to be caused by contact with two infected Taiwanese women who attended a wedding ceremony in Zambales.
The 18-year-old arrived at the country on May 18 and was hospitalized the day after at the Research Institute for Tropical Medicine in Muntinlupa. On May 21, Department of Health (DOH) secretary Francisco Duque confirmed the case being the first Philippine swine flu case. The first confirmed case in the Philippines was publicly announced on May 22, 2009.
Since the outbreak of A(H1N1) in the Americas, President Gloria Macapagal Arroyo urged the Department of Health, the Bureau of Immigration, the Bureau of Quarantine and other concerned agencies to control monitor airport and seaport arrivals for possible flu infection. Thermal imaging equipment were installed at major airports to screen passengers coming from infected countries for flu symptoms. [1] [2] The Philippines may quarantine travelers arriving from Mexico with fever. [3] Also, the importation of hogs from the U.S. and Mexico was banned, [4] and the restriction of swine influenza vaccine use was retracted. First death was reported on June 19, 2009, a 49-year-old female Filipino employee of the Congress, as well as the first death in Asia. [5]

On May 18, 2009, a Filipino family coming from a trip in Houston, Texas arrived in the country. Though infected by the flu, their ten-year-old female child did not exhibit any symptoms except a day after arrival. [14] [15] Due to this, her parents decided to inform the local health authorities about it, prompting Department of Health (DOH) representatives to require the girl to undergo laboratory testing at the Research Institute for Tropical Medicine (RITM) in Muntinlupa. [16]
On Thursday, May 21, health authorities and the RITM were able to confirm that the girl was and the first virus "carrier" through throat specimen tests, and the first A(H1N1) infected in the Philippines.[ citation needed ]
The next day, Health Secretary Duque announced the first flu case at a conference of the World Health Organization (WHO) in Geneva. [16] He then assured members of the media at that time that there was no outbreak of A(H1N1) in the Philippines. [15] The patient was treated with oseltamivir (Tamiflu) and other anti-viral drugs [17] and was discharged on May 28. [18]
During the pandemic, the Department of Health (DOH) has officially counted for 8 A/H1N1 deaths. The DOH kept record until July 29, 2009. A separate European Centre for Disease Prevention and Control report dated September 9, 2009 tallied the number of deaths in the Philippines to 28. [19] The first A(H1N1) fatality in the Philippines was a 49-year-old woman who also had a chronic heart disease who died on June 19. [20] The woman is an employee of the House of Representatives and is a resident of Santa Rosa, Laguna. [21] [22] The case was also the first recorded death in Asia. [23]
In mid-June 2009, the first community outbreak of A(H1N1) in the Philippines was confirmed by the Department of Health. The followed the confirmation of eight mild cases in Jaen, Nueva Ecija. [9] The town was placed under a state of calamity on June 16, 2009, when the town already had 19 confirmed cases. [10] Community outbreaks were also declared in parts of Metro Manila, [22] Baguio, and Eastern Visayas. [24]

In a press conference, Press Secretary Cerge Remonde said that President Arroyo has reiterated her instructions to the DOH, the Bureau of Immigration and all other concerned agencies to be on the top of the situation for regular updates. [25]
The president also ensured that the government is ready to give one million capsules of Tamiflu in case of an epidemic. [16]
Despite the increasing number of cases of A(H1N1) in the country, Press Secretary Remonde said that the Palace is not alarmed with the sudden surge of disease in the Philippines. [26]
The government issued travel advisories for Mexico, the United States and other mostly-infected areas, advising Filipinos to refrain from making unnecessary travel. [27]
Though the influenza virus is now treated mild, DOH will only then treat it like an ordinary flu, whereas it is no longer an obligation to follow all sick persons. [28] According to Duque, if they shall continue their containment policy, the DOH will lose all their resources. He added, "Ituturing na lamang namin ito na parang [isang] karaniwang trangkaso na lamang. Mahirap namang babantayan mo[/natin] lahat ng [mga] 'yan[g pasyente]." (We shall treat this disease like an ordinary influenza). It is so difficult, as you think, to follow and trace all of them (the patients). [29]
On the other hand, DOH shifted into policy of mitigation where patients with symptoms anomaly exhibiting swine flu will just go see a doctor. [29]
Dr. Lyndon Lee Suy, head of the Emerging and Re-emerging Infectious Diseases Program of the Department of Health (DOH), said that the Philippine government, on July 5, still cannot afford to buy mass vaccine, which is estimated to cost PhP 1,000 per dosage. [30] He said that the elderly, among the high-risk group in the Philippines, has a population of around 3.6 million, and vaccination among them requires PhP 3.6 billion (which is a tentative equivalent for the health department's three-year budget). [30] Dr. Lee Suy also added that the stocked 1.5 million anti-viral medicines such as Tamiflu by the DOH is not enough for possible epidemic since most of them are given free to discourage uncontrolled and panic buying. [30] He also said that high-risked group does not only includes elderly, but individuals 5 years and below and with naturally harmful diseases. [30]
On July 7, Roche Philippines announced that it would cut down prices of Tamiflu from PhP 1,000 to PhP 880, to ensure adequate supply of the said anti-viral drug in the Philippines and the rest of the world. [31]
The same day, in a hearing at the Philippine House of Representatives (Congress), Health secretary Francisco Duque requested PhP 19.8 billion fund for H1N1 resistance. He said that the money will be used for buying vaccines (PhP 16 billion), subsidizing poor patients and assistance to the families of poor victims (PhP 3 billion), and implementing rules and rehabilitation of target hospitals for H1N1 patients (PhP 800 million). The Congress questioned the amount of fund largely it is too huge to award and that there are no vaccine yet to buy. On the same hand, Iloilo Representative Ferjenel Biron, also the chairman of the House Committee on Health, asked the secretary to cut its requested budget down to 10% or PhP 2 billion. [32]
On July 27, 2009, the Department of Health announced that the doctors and other health workers such as nurses, aides and volunteers that helped the government to assist H1N1 patients and victims will be among the group that will become the first recipient of 100,000 H1N1 vaccine from the World Health Organization. [33] The vaccine is expected to be out from United States by mid-October. [34]
On August 2, San Juan, Metro Manila officials created a city ordinance seeking PhP 1 million budget seeking for an immediate purchase for health workers in the said city. The resolution will be known as "Battle Against Swine Flu Virus" Ordinance. [35] At the same time, around 3,500 employees of the Caloocan City Hall were given free ant-flu vaccine shots, "to strengthen local government employees' immune system against seasonal flu". [36]
The day after the confirmation of the first case in the country, the Department of Education (DepEd) indicated that classes will continue to start on June 1 as scheduled. [37] In consulting with Secretary Duque, both he and Education Secretary Jesli Lapus reached a decision to go on with the original scheduled date of the opening of classes. Dr. Tayag also said that there is no reason for class suspension unless there is an actual outbreak in the country. [37] Secretary Lapus has instructed schools to carry out seminars and launch an information campaign about the symptoms and virus prevention among schools. [17]
In line with this, Secretary Duque issued on May 30 a response alert system on when schools should suspend their classes. [38] [39]
Following the raising of the response alert level to Level 4, [40] the Commission on Higher Education (CHEd) moved the opening of classes for all colleges and universities nationwide from June 8 to 15, 2009. [41] The postponement of classes was meant to enable the students, especially those coming from abroad vacations, to monitor their health and undergo self-quarantine in case of any virus symptoms will exhibit. [42] Classes from the elementary to the college level were suspended in various schools in the Philippines due to cases of A(H1N1) being confirmed among their population. [43]
Work at the House of Representatives was suspended from June 23 to 28, due to the confirmation of at a death of an employee of the lower house from A(H1N1). [22]
Temporary changes in the conduct of Mass by the Roman Catholic Church in the Philippines was made as a response to the A(H1N1) pandemic. On June 5, Manila Archbishop Cardinal Gaudencio Rosales through instructions to Fr. Genaro Diwa of the Ministry of the Liturgical Affairs of the Archdiocese of Manila, issued an advisory ordering priests to temporarily give communion only by the hand, instead of the traditional mouth; and that holding hands during singing of the Lord's Prayer was to be discouraged. [44] [45] An Oratio Imperata obligatory prayer on H1N1 was also obligated to be recited by mass participants. [44]
On June 23, the Archbishop of Jaro (in Iloilo) Angel Lagdameo ordered local churches to empty holy water stoups whereas churchgoers are strongly advised to do sign of the cross instead of using holy water. [46]
Around two months after the memorandum ordering extra precautions on the mob regarding catching flu in churches, the Catholic Bishops Conference of the Philippines (CBCP) announced that the new flu strain failed to drag Filipino believers out of churches. According to Msgr. Achilles Dakay of the Roman Catholic Archdiocese of Cebu, church attendance in the archdiocese remained normal despite advisories. [47]
Tourism secretary Joseph Ace Durano as of 24 May said that there were no reported cancellations in any tourism booking so far. [48]

Mitigation means that we only do early detection and aggressive treatment of cases as they come especially for those with high-risk preexisting conditions. Those manifesting with mild symptoms can be managed and monitored at home so that only patients at risk who develop complications will have to be hospitalized. H1N1 will now become part of our Influenza-like Illness (ILI) surveillance activity and one of our notifiable diseases. It offers little benefit to do extensive tracing of this virus when it is clear that the disease can be passed on to others at a rate faster than it will ever be humanly possible to find the contacts.
There were at least 50 infected provinces and cities in the Philippines (excluding Metro Manila component cities):
On the same hand, Metro Manila has the following infected cities:
Influenza A virus (IAV) is a pathogen with strains that infect birds and some mammals, as well as causing seasonal flu in humans. Mammals in which different strains of IAV circulate with sustained transmission are bats, pigs, horses and dogs; other mammals can occasionally become infected.
Swine influenza is an infection caused by any of several types of swine influenza viruses. Swine influenza virus (SIV) or swine-origin influenza virus (S-OIV) refers to any strain of the influenza family of viruses that is endemic in pigs. As of 2009, identified SIV strains include influenza C and the subtypes of influenza A known as H1N1, H1N2, H2N1, H3N1, H3N2, and H2N3.
In virology, influenza A virus subtype H1N1 (A/H1N1) is a subtype of influenza A virus. Major outbreaks of H1N1 strains in humans include the 1918 Spanish flu pandemic, the 1977 Russian flu pandemic and the 2009 swine flu pandemic. It is an orthomyxovirus that contains the glycoproteins hemagglutinin (H) and neuraminidase (N), antigens whose subtypes are used to classify the strains of the virus as H1N1, H1N2 etc. Hemagglutinin causes red blood cells to clump together and binds the virus to the infected cell. Neuraminidase is a type of glycoside hydrolase enzyme which helps to move the virus particles through the infected cell and assist in budding from the host cells.
An influenza pandemic is an epidemic of an influenza virus that spreads across a large region and infects a large proportion of the population. There have been six major influenza epidemics in the last 140 years, with the 1918 flu pandemic being the most severe; this is estimated to have been responsible for the deaths of 50–100 million people. The 2009 swine flu pandemic resulted in under 300,000 deaths and is considered relatively mild. These pandemics occur irregularly.
Influenza A virus subtype H3N2 (A/H3N2) is a subtype of viruses that causes influenza (flu). H3N2 viruses can infect birds and mammals. In birds, humans, and pigs, the virus has mutated into many strains. In years in which H3N2 is the predominant strain, there are more hospitalizations.
The 2009 swine flu pandemic, caused by the H1N1/swine flu/influenza virus and declared by the World Health Organization (WHO) from June 2009 to August 2010, was the third recent flu pandemic involving the H1N1 virus. The first identified human case was in La Gloria, Mexico, a rural town in Veracruz. The virus appeared to be a new strain of H1N1 that resulted from a previous triple reassortment of bird, swine, and human flu viruses which further combined with a Eurasian pig flu virus, leading to the term "swine flu".
The 2009 flu pandemic in the United States was caused by a novel strain of the Influenza A/H1N1 virus, commonly referred to as "swine flu", that was first detected on 15 April 2009. While the 2009 H1N1 virus strain was commonly referred to as "swine flu", there is no evidence that it is endemic to pigs or of transmission from pigs to people; instead, the virus spreads from person to person. On April 25, the World Health Organization declared a public health emergency, followed concurringly by the Obama administration on April 26.
The 2009 swine flu pandemic in Canada was part of an epidemic in 2009 of a new strain of influenza A virus subtype H1N1 causing what has been commonly called swine flu. In Canada, roughly 10% of the populace has been infected with the virus, with 428 confirmed deaths ; non-fatal individual cases are for the most part no longer being recorded. About 40% of Canadians have been immunized against H1N1 since a national vaccination campaign began in October 2009, with Canada among the countries in the world leading in the percentage of the population that has been vaccinated. The widespread effect of H1N1 in Canada raised concerns during the months leading to the XXI Olympic Winter Games, which took place in Vancouver in February 2010.
This article covers the chronology of the 2009 novel influenza A (H1N1) pandemic. Flag icons denote the first announcements of confirmed cases by the respective nation-states, their first deaths, and relevant sessions and announcements of the World Health Organization (WHO), the European Union , and the U.S. Centers for Disease Control (CDC).
In March and April 2009, an outbreak of a new strain of influenza commonly referred to as "swine flu" infected many people in Mexico and other parts of the world, causing illness ranging from mild to severe. Initial reports suggested that the outbreak had started in February due to farming practices at a pig farm half-owned by Smithfield Foods. Smithfield Foods stated that it had found no clinical signs or symptoms of the presence of swine influenza in the company's swine herd, or among its employees at its joint ventures in Mexico, that it routinely administers influenza virus vaccination to their swine herds and that it conducts monthly testing for the presence of swine influenza. The new strain was identified as a combination of several different strains of Influenzavirus A, subtype H1N1, including separate strains of this subtype circulating in humans and in pigs.
The 2009 swine flu pandemic was a global outbreak of a new strain of influenza A virus subtype H1N1, first identified in April 2009, termed Pandemic H1N1/09 virus by the World Health Organization (WHO) and colloquially called swine flu. The outbreak was first observed in Mexico, and quickly spread globally. On 11 June 2009, the WHO declared the outbreak to be a pandemic. The overwhelming majority of patients experienced mild symptoms, but some persons were in higher risk groups, such as those with asthma, diabetes, obesity, heart disease, who were pregnant or had a weakened immune system. In the rare severe cases, around 3–5 days after symptoms manifest, the sufferer's condition declines quickly, often to the point of respiratory failure.
Australia had 37,537 confirmed cases of H1N1 Influenza 2009 and 191 deaths reported by Department of Health but only 77 deaths reported by the Australian Bureau of Statistics. The actual numbers are much larger, as only serious cases warranted being tested and treated at the time. Suspected cases have not been reported by the Department of Health and Ageing since 18 May 2009 because they were changing too quickly to report. Sources say that as many as 1600 Australians may have actually died as a result of this virus. On 23rd of May 2009 the federal government classified the outbreak as CONTAIN phase except in Victoria where it was escalated to the SUSTAIN phase on 3rd of June 2009. This gave government authorities permission to close schools in order to slow the spread of the disease. On 17 June 2009 the Department of Health and Ageing introduced a new phase called PROTECT. This modified the response to focus on people with high risk of complications from the disease. Testing at airports was discontinued. The national stockpile of antiviral drugs were no longer made available to people with the flu unless there were more than mild symptoms or a high risk of dying.
This article deals with the status and efforts regarding the 2009 swine flu pandemic by country and continent/region.
The pandemic H1N1/09 virus is a swine origin influenza A virus subtype H1N1 strain that was responsible for the 2009 swine flu pandemic. This strain is often called swine flu by the public media due to the prevailing belief that it originated in pigs. The virus is believed to have originated around September 2008 in central Mexico.
The 2009 flu pandemic in Asia, part of an epidemic in 2009 of a new strain of influenza A virus subtype H1N1 causing what has been commonly called swine flu, afflicted at least 394,133 people in Asia with 2,137 confirmed deaths: there were 1,035 deaths confirmed in India, 737 deaths in China, 415 deaths in Turkey, 192 deaths in Thailand, and 170 deaths in South Korea. Among the Asian countries, South Korea had the most confirmed cases, followed by China, Hong Kong, and Thailand.
The 2009 swine flu pandemic in North America, part of a pandemic in 2009 of a new strain of influenza A virus subtype H1N1 causing what has been commonly called swine flu, began in the United States or Mexico.
The 2009 flu pandemic in Europe was part of a pandemic involving a new strain of influenza, subtype H1N1. H1N1 is commonly called swine flu. The pandemic infected at least 125,550 people in Europe. There were 458 confirmed deaths in Turkey, 438 confirmed deaths in Russia, and 457 confirmed deaths in the United Kingdom.
The 2009 flu pandemic in the Philippines began on May 21, 2009, when a young Filipina girl first contracted the A(H1N1) virus while in the United States. In the following days, several local cases were reported to be caused by contact with two infected Taiwanese women who attended a wedding ceremony in Zambales.
The 2009 swine flu pandemic reached various parts of India. Soon after the outbreak of H1N1 virus in the United States and Mexico in March, the Government of India started screening people coming from the affected countries at airports for swine flu symptoms. The first case of the flu in India was found on the Hyderabad airport on 13 May, when a man traveling from US to India was found H1N1 positive. Subsequently, more confirmed cases were reported and as the rate of transmission of the flu increased in the beginning of August, with the first death due to swine flu in India in Pune, panic began to spread. As of 24 May 2010, 10193 cases of swine flu have been confirmed with 1035 deaths.
The 2009 swine flu pandemic was a global outbreak of a new strain of influenza A virus subtype H1N1, first identified in April 2009, termed Pandemic H1N1/09 virus by the World Health Organization (WHO) and colloquially called swine flu. The outbreak was first observed in Mexico, and quickly spread globally. On 11 June 2009, WHO declared the outbreak to be a pandemic. The overwhelming majority of patients experience mild symptoms", but some persons are in higher risk groups, such as those with asthma, diabetes, obesity, heart disease, or who are pregnant or have a weakened immune system. In the rare severe cases, around 3–5 days after symptoms manifest, the person's condition declines quickly, often to the point respiratory failure.
