The director-general of the WHO, Tedros Adhanom Ghebreyesus, announces that Covid-19 is over. However, he emphasized that governments and the global population must not let their guard down or their precautions as the virus continues to circulate in virtually all countries of the world.

It was on January 23, 2020, when the WHO alerted the international community about the outbreak of this new and relentless virus that originated in Wuhan, China, from the headquarters of the WHO in Geneva, Switzerland. To date, the precise origin of the virus is unknown, a crucial fact to understand its behavior. Although most studies suggest that it emerged in the Wuhan market in China and that it is a virus that jumped from an animal species, such as bats or raccoons, to humans, the WHO has not ruled out the possibility that it originated due to an accident in a laboratory located a few meters away from said market.

The WHO has asked the Chinese government for greater transparency and information on the origins of the virus, especially following the leakage of information from the Chinese scientific community in March of this year, which pointed to the outbreak starting in the Wuhan market due to infected raccoons.

It was on December 30, 2019, around 2:00 p.m., when the head of the Emergency Department of the Central Hospital of Wuhan received the results of a test performed by the Capital Bio Medicals sequencing laboratory in Beijing, which confirmed the presence of a virus similar to SARS. Several people had been admitted to hospitals in the central city of Wuhan, after falling ill with high fever and pneumonia.

The first case was confirmed on December 1 with a man in his 70s. It was later discovered that many of the cases were connected to a live animal market at the Wuhan seafood wholesale market, and doctors began to suspect that it was not SARS but a new virus.

The Chinese Ministry of Health informed the WHO that samples from lung infections had been sent to genetic sequencing companies to identify the cause of the disease, and preliminary results had indicated a new coronavirus. In Geneva, correspondents were called to a press conference to inform the international community about the outbreak of the new virus.

At that time, there was a huge information gap from China, and according to a recent model from Northwestern University in Boston, between 2,300 and 4,000 people were likely already infected. In addition, they concluded that the number of cases doubled in a matter of days. Epidemiologists were already talking about a pandemic.

"'There has been no evidence of person-to-person transmission' is not good enough. We need to see the data," says Mike Ryan, director of the WHO's health emergency program. Despite the fact that WHO experts suspected that there was person-to-person transmission, the UN health agency could not confirm this until three weeks later.

One of those doctors was Li Wenliang, the ophthalmologist whose warning had gone viral on social media. He signed a confession. In February, he died of Covid-19. He is now known as the hero of Wuhan.

According to reports that have come to light, a health worker at Li's hospital, Wuhan Central, said that "there were so many people with a fever, and the hospital was out of control. We started to panic, but the hospital
