The first diagnosis of COVID-19 was made by a woman named Wei, who was engaged in live shrimp trading in the Huanan Market, which became the epicenter of this disease. It is not clear where this woman got the virus from and under what circumstances she picked it up.
Earlier media claimed that the first case of coronavirus infection in China was detected on November 17, 2019. Then the still unknown SARS-CoV-2 virus was detected on November 17 at a 55-year-old resident of the Chinese province of Hubei. Later, Chinese doctors recorded one to five new cases of infection daily, but only at the end of December it became clear that they were dealing with a new type of coronavirus.
However, a woman named Wei was the first patient to have a newly confirmed coronavirus infection. It is not known how she is associated with the first carrier of coronavirus in the country, however, she rented an apartment near this market and became the first to contact the clinic with such symptoms. Until the end of 2019, scientists discovered 27 more people with similar symptoms who lived in this house and had contacts with the Huanan Market. 11 people from the first group who became infected after the onset of symptoms turned to small clinics near this market, located in old residential buildings. Now all these private clinics are closed.
Today, scientists continue to search for the null patient with whom this pandemic began.
