China will examine thousands of samples from a blood bank in Wuhan as part of an investigation into the origin of COVID-19.
According to CNN, citing a Chinese official, several thousand blood samples are going to be examined in the country. They were collected from local residents from October to November 2019.
It was during this period, according to experts from the World Health Organization (WHO), that a new virus began to spread in China.
China is preparing to study tens of thousands of samples from the Wuhan city blood bank as part of an investigation into the origins of COVID-19.
A representative of the Chinese specialized agency explained that preparations for carrying out the relevant procedures are already underway.
According to him, the blood samples had to be kept intact for two years in case of legal claims from donors or recipients of donated blood. Now this period has passed, so biologists from China will study the collected materials in the near future.
As the experts explained, it is in these blood samples that there may be antibodies indicating that the patient at the time of taking blood from him was infected or had a coronavirus infection. This way you can track the exact beginning of the spread of the virus, as well as its source.
