January to February 2020 The Philippines reported its first suspected case of COVID-19 in January 2020; it involved a 5-year-old boy in
Cebu who arrived in the country on January 12 with his mother. At that time, the Philippines could not conduct COVID-19 tests. The boy tested positive for "non-specific pancoronavirus assay" at the
Research Institute for Tropical Medicine (RITM). Samples from the boy were also sent to the Victorian Infectious Disease Reference Laboratory in
Melbourne, Australia, to determine the specific coronavirus strain. The RITM developed the capability to confirm COVID-19 cases in response to the emergence of suspected cases and began conducting confirmatory tests on January 30, 2020. on January 25 after seeking a consultation due to a mild cough. At the time of the confirmation announcement, the woman was already
asymptomatic. On February 5, the Philippines
Department of Health (DOH) confirmed a third case in a 60-year-old Chinese woman who flew into
Cebu City from Hong Kong on January 20. She then traveled to
Bohol, where she consulted a doctor at a private hospital on January 22 due to fever and
rhinitis. Samples taken from the patient on January 24 returned negative, but the DOH was notified on February 3 that samples taken on January 23 tested positive for the virus. The patient recovered on January 31 and was allowed to return to China.
March 2020 After a month of reporting no new cases, the DOH announced on March 6 that there were two cases involving two Filipinos. One was a 48-year-old man with a travel history in Japan that returned on February 25 and reported symptoms on March 3. The other was a 60-year-old man with a history of hypertension and diabetes who experienced symptoms on February 25 and was admitted to a hospital on March 1 when he experienced pneumonia. The DOH confirmed that the fifth case had no travel history outside the Philippines and was, therefore, the first case of local transmission. A sixth case was later confirmed in a 59-year-old woman who was married to the fifth case. Since then, the Department of Health recorded a continuous increase in the number of COVID-19 cases in the country. Cases abroad involving foreigners with travel history in the Philippines were reported in early March 2020. The first three recorded cases involving an Australian, a Japanese, and a Taiwanese national had a history of visiting the Philippines in February 2020. Though it was unconfirmed whether or not they had contracted the virus while in the Philippines, speculations arose of undetected local transmissions in the country due to prior confirmation of the Philippines' first case of local transmission. Retrospective studies have been conducted to determine the strain of the virus responsible for the community outbreak of COVID-19 in the Philippines since March 2020. In May 2020, Edsel Salvaña, director of the
National Institute of Molecular Biology and Biotechnology and member of the
Inter-Agency Task Force for the Management of Emerging Infectious Diseases (IATF-EID), said that the strain responsible for the COVID-19 outbreak in the country that started in March 2020 was closely related to the strain affecting India at the time. The virus strain's family tree was said by Salvaña to have first appeared in China and Australia. Several measures were implemented to mitigate the spread of the disease in the country, including travel bans to
mainland China,
Hong Kong,
Macau, and
South Korea. On March 7, 2020, the
Department of Health raised its "Code Red Sub-Level 1", with a recommendation to the
President of the Philippines to impose a "public health emergency" authorizing the DOH to mobilize resources for the procurement of safety gear and the imposition of preventive quarantine measures. On March 12, President Duterte declared "Code Red Sub-Level 2", issuing a partial lockdown on
Metro Manila for 30 days to prevent the nationwide spread of COVID-19. The lockdowns were expanded on March 16, placing the entirety of
Luzon under an "
enhanced community quarantine" (ECQ). Other local governments outside Luzon followed
in implementing similar lockdowns. On March 17, President Duterte issued Proclamation No. 929, declaring the Philippines under a
state of calamity for a tentative period of six months. On March 20, four facilities, namely the
Southern Philippines Medical Center in
Davao City,
Vicente Sotto Memorial Medical Center in Cebu City,
Baguio General Hospital and Medical Center in
Benguet, and the San Lazaro Hospital in Manila (where the first case was admitted), began conducting tests alongside the RITM. Other facilities began operations as well in the following days.
April to May 2020 on April 8, 2020. By April 6, COVID-19 was determined to have spread to all 17 regions of the Philippines with the confirmation of a patient confined at a hospital in
Surigao City who had been in the
Caraga region since March 12 after traveling from Manila. On April 7, President Duterte accepted the recommendation of the Inter-Agency Task Force for the Management of Emerging Infectious Diseases to extend the ECQ in Luzon until April 30. On April 17, Dr. Ted Herbosa, a special adviser of the National Task Force Against COVID-19, said that the country had been able to bring down the viral disease's reproduction number from 1.5 to 0.65, meaning that the average number of people a person could infect decreased from more than one to less than one. Recent data at the time suggested that the country was doing better in "
flattening the curve", but Herbosa warned of a "resurgence" and said the Philippines must ramp up mass testing in order to isolate cases and avoid further transmission of COVID-19. The ECQ in Luzon was extended until May 15 in some areas, including Metro Manila,
Calabarzon,
Central Luzon (except
Aurora),
Pangasinan, and Benguet. ECQ measures were also extended in the provinces of
Iloilo and Cebu, as well as in Davao City. The rest of the country was placed under general community quarantine (GCQ). (Ambo) On May 14,
Typhoon Vongfong (local name: Ambo) landed on
Samar Island. Tens of thousands of people under lockdown orders evacuated their homes, complicating COVID-19 containment efforts. To prevent the spread of coronavirus, shelters in the central Philippines only accepted half of their maximum capacity; masks were required when evacuating. In Metro Manila, the typhoon blew away many makeshift tents used as triage centers, testing facilities, and wards. 40 provinces and 11 cities considered "low risk" were initially released from community quarantine measures, but were eventually upgraded to a "modified general community quarantine" (MGCQ) after requests from LGUs. On May 14, the Philippine government declared the entire country temporarily under GCQ except for Metro Manila, Laguna and Cebu City, which continued to implement MECQ. The IATF-EID also reportedly considered the reclassification of provinces and cities in Central Luzon as "high-risk areas" under MECQ. On May 16, after receiving petitions from LGUs, the IATF-EID revised its quarantine policies: Cebu City and
Mandaue were placed under ECQ, while Metro Manila, Laguna, and Central Luzon (except Aurora and
Tarlac) were under MECQ. The rest of the country was placed under GCQ.
June to July 2020 Quarantine measures were loosened throughout the country starting on June 1, with areas formerly under ECQ transitioning to GCQ. This led to a significant rise in the number of confirmed cases. The official start of elementary and secondary school classes, which customarily began in June, was postponed to October. The Bayanihan to Heal as One Act expired in June. According to the national government, the law expired on June 25 due to its
sunset provision, although some interpreted it as having expired as early as June 5. For example, Senator
Sonny Angara argued that per the Constitution, "emergency powers cease upon the next adjournment of Congress" and that he considered the Bayanihan Act as an emergency measure. Upon the law's expiration, the national government was no longer required to provide cash subsidies to families affected by community quarantine measures. In early June, the DOH created the COVID-19 Surveillance and Quick Action Unit to improve data collection and reconciliation. It launched its "Oplan Recovery" program to address discrepancies between its counts of recovered patients and LGUs' counts. Mild and asymptomatic cases recorded starting July 15 were marked as recovered after 14 days from test swab collection, following the WHO's criteria for discharging COVID-19 patients. These changes led to over 37,100 cases being relabeled as recoveries on July 30.
August 2020 On August 2, the Philippines surpassed the 100,000-case mark as the country continued to report around 2,000–3,000 new cases per day. On August 6, the country's cumulative total exceeded that of Indonesia, giving it the highest number of recorded COVID-19 cases in Southeast Asia, a position it held until October 15. A modified enhanced community quarantine (MECQ) was established in Metro Manila, Bulacan, Cavite, Laguna, and Rizal from August 4 to 18 in response to the petition of medical front-line workers requesting an ECQ in Metro Manila. In early August, the Philippine Senate held hearings on the
Philippine Health Insurance Corporation (PhilHealth) corruption scandal; its executives were alleged to have used the pandemic as a cover-up to steal billions of pesos. On August 13, the
Philippine Genome Center (PGC) reported the new, globally dominant variant of the virus was detected in the Philippines. This more infectious variant was associated with the sudden increase of new cases in July. By August 18, the DOH had identified 1,302 COVID-19 clusters throughout the country, with the majority in Metro Manila.
September to November 2020 On September 11, President Duterte signed Republic Act No. 11494, or the
Bayanihan to Recover as One Act, into law, providing additional funds to mitigate the pandemic's economic impact. He extended the
state of calamity until September 2021 through Proclamation No. 1021, filed September 18. The IATF-EID announced on September 18 that all cemeteries,
columbariums, and memorial parks nationwide will be closed from October 29 to November 4 to prevent social gatherings traditionally conducted as part of the
All Saints' Day observance, similar to the proposal made by Metro Manila mayors few days prior. Filipinos adapted their rituals by visiting cemeteries early or observing at home. COVID-19 had spread to all provinces in the Philippines by September 28, when
Batanes recorded its first case.
December 2020 In mid-December, a new, more contagious
variant of known as
Lineage B.1.1.7 was identified in the
United Kingdom. This led to several countries restricting or banning travel from the United Kingdom, including the Philippines. The Philippines also banned travel from 19 other nations which reported cases of more infectious SARS-CoV-2 variants. The DOH announced at a briefing held in January 2021 that the UK variant arrived in the Philippines as early as December 2020. One of the samples collected by the health department on December 10 tested positive for the variant on January 21, 2021.
January to February 2021 By January 2021, the DOH was monitoring at least two other noted mutations besides the UK variant, namely the
501.V2 variant from
South Africa and another variant from
Malaysia. On January 5, 2021, Hong Kong health officials reported detecting the UK variant in a 30-year-old woman who arrived in the city from the Philippines on December 22, 2020, raising concerns that the strain may already be in the Philippines. On January 13, the DOH announced that the UK variant has been detected in the country when a 29-year-old man from Quezon City, who returned from the United Arab Emirates on January 7, tested positive for COVID-19. Thirteen individuals who came in contact with the man also tested positive for the variant days later. On January 22, 16 new cases associated with the UK variant were confirmed in several regions, including Benguet, Laguna, and Mountain Province. A case each in Benguet and Laguna had no known contact with a confirmed case or a travel history outside the country. The
Food and Drug Administration (FDA) issued
emergency use authorization to the
Pfizer–BioNTech and
Oxford–AstraZeneca COVID-19 vaccines on January 14 and 28 respectively. On February 18, the DOH in Central Visayas announced that two "mutations under investigation", E484K and N501Y, were discovered in Cebu.
March to April 2021 The DOH announced the detection of the
South African variant of in
Pasay on March 2. On March 13, Lineage P.1, commonly known as the
Brazilian variant, was detected in the country. The DOH also confirmed the mutations discovered in February formed a variant, which they called P.3, belonging to the B.1.1.28 lineage like P.1. The day prior, Japan reported the P.3 variant was found in a man who traveled from the Philippines. The WHO named the P.3 variant "Theta" on March 31, labelling it a "variant of concern". On March 17, the
Philippine Statistics Authority (PSA) reported that there were at least 27,967 deaths caused by or associated with COVID-19 by the end of 2020, more than twice the DOH's count. 19,758 of these were tagged "COVID-19 virus not identified", while 8,209 were tagged "COVID-19 virus identified". The discrepancy between the DOH and PSA tallies is due to the PSA's inclusion of probable and suspect cases. As a response to the recent spike in cases, the
Greater Manila Area, which the government called "NCR Plus", was placed under general community quarantine (GCQ) on March 22, originally set to expire on April 4. It was raised to an enhanced community quarantine (ECQ) from March 29 to April 11 as the positivity rate of the area remained high. On April 26, the country surpassed 1 million cases.
May to June 2021 On May 11, the country detected its first two cases of the
Delta variant in two Filipino seafarers who returned in April. In the summer of 2021, COVID-19 infections increased significantly in primarily rural regions. As of June 7, Mindanao accounted for a quarter of new cases, more than Metro Manila. Dozens of people in
Dipolog were "treated for coronavirus outside in makeshift tents, or hooked up to oxygen tanks while sitting in their vehicles, due to the lack of hospital beds", according to an
Al Jazeera article.
July 2021 On July 16, presidential spokesman
Harry Roque announced Indonesian travelers were forbidden from entering the country from July 16–31 to limit the spread of the Delta variant, which had become the dominant variant in several countries. The same day, the country detected 16 new Delta variant cases, 11 of which were locally transmitted. On July 29, the Department of Health (DOH) reported 97 new cases of the Delta variant, bringing the total to 216. Of the newly reported cases, 88 were local, 6 were returning overseas Filipinos, and 3 were unknown.
August 2021 On July 30, the government placed Metro Manila under
Enhanced Community Quarantine (ECQ), effective August 6 and ending August 20, due to rising cases of the Delta variant. On August 5, the DOH detected 116 new Delta variant cases, bringing the total to 331. Of the additional cases, 95 were local, 1 was returning from overseas, and the remaining 20 had unknown provenance. The DOH also reduced the Delta variant case count reported on July 29 from 216 to 215, as one case was found to have been tested in two different laboratories. On the same day, President
Rodrigo Duterte, following the recommendation of the IATF, put the provinces of
Laguna,
Cagayan de Oro, and
Iloilo City under ECQ from August 6 to 15;
Lucena Cavite,
Rizal, and
Iloilo were put under modified enhanced community quarantine (MECQ), while
Batangas and
Quezon were under general community quarantine (GCQ) with heightened restrictions. On August 15, the DOH detected the country's first case of the
Lambda variant in a 35-year-old female. The DOH said the patient was asymptomatic and marked as recovered after undergoing the 10-day isolation period. The DOH also detected 182 new cases of the Delta variant, as well as 41 of the Alpha variant, 66 of the Beta variant, and 40 of the Theta variant. On August 19, Metro Manila and the province of Laguna were placed under MECQ from August 21 to 31. The World Health Organization released a statement on August 28 that the Delta variant had become the dominant variant of in the Philippines, with community transmission occurring (meaning infected individuals were no longer in direct contact).
September 2021 On September 1, the number of COVID-19 cases in the country surpassed 2 million. On September 3, the
Philippines Food and Drug Administration (FDA) approved the emergency use of
Moderna's
COVID-19 vaccine for minors aged 12 to 17. The government introduced a new 5-tier Alert Level System (ALS) to replace the ECQ, MECQ, GCQ, and MGCQ labels, with a pilot implementation in Metro Manila beginning on September 16.
October 2021 On October 15, the government began the vaccination of minors with comorbidities against COVID-19. The coverage of the ALS was expanded to include LGUs in the
Calabarzon,
Central Visayas, and
Davao regions on October 20. On October 25, the DOH confirmed the first case of the B.1.1.318 variant in the country. The DOH also detected 380 more cases of the Delta variant, as well as 104 Alpha variant cases and 166 Beta variant cases.
November 2021 On November 8, the country detected its first case of the
B.1.617.1 variant, formerly called the Kappa variant, in a 32-year-old male from
Floridablanca. The Alert Level System was rolled out nationwide on November 22.
December 2021 The
Omicron variant was first detected in the Philippines on December 15. The cases involved two travelers from Nigeria and Japan who arrived in the Philippines on November 30 and December 1, respectively. By December 28, there were four Omicron cases confirmed, all international travelers.
January 2022 On January 15, the DOH confirmed community transmission of the Omicron variant in
Metro Manila, which caused a spike in cases that began in late December 2021 and continued through the first half of January 2022. A shortage on
analgesics like
paracetamol and other drugs for flu-like symptoms was reported. The DOH assured the public there is no shortage, though the
Department of Trade and Industry (DTI) noted some brands were unavailable in certain areas due to logistical issues.
October 2022 The first confirmed cases of the
Omicron XBB subvariant and XBC variant were detected in the Philippines on October 17. == Medical response ==
