MANILA, Philippines — The novel coronavirus disease 2019 (COVID-19) started as a mysterious virus that caused pneumonia in some cases in Wuhan, China, in December 2019.
Few had expected it would eventually disrupt the natural course of life globally, paralyzing economies, devastating communities and keeping billions of people confined to their homes.
As 2020 closes, the virus SARS Cov2, which causes COVID-19, has so far infected 81 million people worldwide and killed 1.7 million. In the Philippines, Department of Health (DOH) data as of Dec. 29 showed 471,526 cases with 439,016 recoveries and 9,162 deaths.
INQUIRER.net looks back at how COVID-19 emerged from being a nameless disease to being the biggest health crisis the world had to face in modern history.

The case, which was the second reported in the country, involved a 44-year old Chinese man who was admitted to San Lazaro Hospital in Sta. Cruz, Manila for pneumonia after suffering from fever, cough and sore throat, which were symptoms of the new disease.
The Chinese man was companion of the 38-year-old Chinese woman who was earlier confirmed as the first case of infection in the Philippines.
Both patients are from Wuhan and arrived in the Philippines last January 21.
Feb. 4
Japan has quarantined a cruise ship carrying 3,711 people and was testing those on board for the virus after a passenger, who had already disembarked from the ship, was found to be infected in Hong Kong.

The Philippines government imposes a strict lockdown measure, now known as enhanced community quarantine (ECQ), which required people to stay at home, leading to closures of restaurants, bars, malls, theatres, gyms and factories that are deemed nonessential. The closure of many establishments became permanent, stripping millions of people of their jobs.
March 18
WHO Director General Tedros Adhanom Ghebrevesus announced that the first vaccine trial for the virus has begun, 60 days after its genetic sequencing had been shared by China.
He called it an “an incredible achievement.”
WHO and partners also organized a study to compare untested treatments throughout several countries.
“This large, international study is designed to generate the robust data we need to show which treatments are the most effective. We have called this study the SOLIDARITY Trial,” the WHO chief said.
Feb. 11
WHO christened the new disease as COVID-19.
The UN health agency said that “co” stands for “corona”, “vi” for “virus” and “d” for “disease”, while “19” was for the year it was first identified on Dec. 31.
WHO had earlier given the virus the temporary name of “2019-nCoV acute respiratory disease”.

Sept. 1
COVID-19 cases across the globe hit 25.3 million

American biotechnology firm Moderna announced that initial phase 3 trial data showed that its coronavirus vaccine is more than 94% effective against SARS Cov2.

As 2020 draws to a close, coronavirus continued to be relentless in its spread.
On Dec. 14, the Public Health England (PHE) identified a “new variant” of SARS-CoV-2 across the south and east of England, which is potentially more infectious.
It was named “VUI-202012/01” – also known as B.1.1.7 – which means the first Variant Under Investigation in December 2020.
The discovery of a new variant came as China exerted efforts to change the virus’ storyline and show that it did not originate from its shores.
British Prime Minister Boris Johnson also imposed stricter restrictions in the UK after scientists, according to him, found that the new variant “may be up to 70 percent more transmissible than the earlier strain.”
Despite clarifications by the WHO and the US that there was no hard evidence yet to prove that the UK variant was more contagious, many countries, including the Philippines, have decided to enforce travel bans and restrictions.
This was after several cases of infection caused by the UK coronavirus variant have been confirmed in different countries across the world, including in the United States where a case of infection caused by the new virus variant was found in Colorado.
As countries take steps to slow the spread of coronavirus or stop it, especially with the emergence of a new variant, the world holds its breath for what’s in store for it in 2021.
People are likely to usher in the New Year with masks and social distancing as part of their daily lives. Everyone is hopeful, though, that normalcy, or the days when people can freely walk outside their homes, hug and kiss their loved ones without fear of infection, would still return.
