The World Health Organization (WHO) expert group proposed further investigation after an abnormality was discovered during the Covid-19 origin investigation in Wuhan, China.
After nearly a month, the WHO expert group, including independent experts, has completed the process of investigating the origin of Covid-19 in China. The preliminary report of the investigation is expected to be released in the next few days. The preliminary report is believed to recommend extending the contact tracing of the first Covid-19 patient in Wuhan, China’s Hubei province, according to the sources familiar with the matter. WHO experts were surprised to discover that Chinese scientists were not paying sufficient attention to the tracking of the first Covid-19 patient contact in Wuhan, as well as the food supply chain in the Hai market. South China production Professor Yanzhong Huang, a senior public health expert, said he was surprised that Chinese officials “did not invest the effort in investigating such two important clues”.
One of the two aspects that WHO experts recommend is further investigation into the exposure history of the first confirmed Covid-19 patient in China on December 8, 2019. The patient’s identity is not disclosed, but is known to be a man in his 40s, living with his wife and children and not far from his place of residence near the time of the discovery of Covid-19. The man had no connection with the Hoa Nam seafood market, which is believed to be linked to the early stages of the Covid-19 outbreak. The patient is not a crowd of sports lovers, his main hobby is surfing the internet.
Peter Daszak, a member of WHO’s team of 17 experts, said the patient said his parents went to a fresh animal market in Wuhan at that time, but not a Hainan seafood market. “I find it remarkable that other markets in Wuhan, not only Hainan market also sell wildlife products (middlemen may have transmitted Covid-19),” Mr. Daszak said.
The scientists confirmed to the WHO expert group that the parents of the first Covid-19 patient had a negative result, but it seems that Chinese authorities did not trace their contact at that market.
“If a patient’s parents have a negative result, it doesn’t mean that their exposure is not required. This needs to be done now to find out about the spread of Covid-19 in Wuhan,” Mr. Daszak said. .
Professor Maureen Miller, an infectious disease specialist at Columbia University, said that the patient’s lack of contact with live markets and lack of movement around the time of Covid-19 was confirmed. has been spreading in the community in China since before.
Another recommendation is expected to be made in the WHO expert group’s preliminary report that is to immediately investigate the supply chain of the South China seafood market. Mr. Daszak said that Chinese scientists have provided WHO experts with a list of agricultural products of the southern provinces of this country including Yunnan, Guangxi, Guangdong that supply the South China seafood market in Wuhan.
“There will be many recommendations which include traceability of products from farms, testing farmers, interviewing and testing their loved ones, finding clues whether the epidemic has spread there. Before the outbreak in Wuhan or not. No one had checked the animals before. Those farms are now closed, “Mr. Daszak said.
Mr. Daszak said that Chinese scientists went to inspect wildlife farms in and around Hubei province, and some “clue suppliers”, but not southern ones. he and WHO experts are most concerned about.
According to him, examining the supply chain can help scientists determine which animals (or humans) have passed the virus to each other before it can be transmitted to humans. “Transmission may have appeared a little earlier, around November or even October,” Mr. Daszak said, referring to the time when the SARS-CoV-2 virus was transferred from animals to humans.
On the Chinese side, the Ministry of Foreign Affairs and the National Health Commission of the country are not available for comment. However, Chinese Foreign Ministry spokesman Hoa Xuan Oanh said on February 18 that China has investigated a very “thoroughly, professionally on scientific basis, with WHO experts”.
