What is the transmission host of novel coronavirus?
The World Health Organization (WHO) is focusing on “rabbits and ferret badgers” as possible vectors for novel coronavirus, Jiemian News quoted the Wall Street Journal as saying Wednesday.
The Wall Street Journal reported that zoologist Peter Dasak, a member of the WHO panel, said in an interview that a ferreat badger found in a freezer at a seafood market in southern China could still carry the virus and act as an intermediate host, even though it tested negative.
Mr. Dasak added that rabbits found in the market were also “susceptible to novel coronavirus.”
Another panelist, Dutch virologist Marion Koopmans, agreed that ferret badgers and rabbits are seen as capable of carrying and spreading novel coronavirus.
WHO: Novel coronavirus’ highly unlikely ‘from laboratory leak
Mr. Dasak said investigations found that the supply chain for wildlife stalls at the market included southern Chinese provinces, which border Vietnam, Laos and Myanmar.
This is a key finding, he said, because two close relatives of the novel coronavirus virus have been found in bats in Yunnan, while pangolins have been found with similar viruses in Guangxi and Guangdong.
But Dasak and other panel members said they still need to look at other countries, especially in Southeast Asia, where similar coronaviruses have recently been found in places like Thailand and Cambodia.
Dominic Dwyer, an Australian microbiologist who is a member of the panel, also said in an interview that it made sense to include Southeast Asia and more countries in the tracing effort.
According to @cgtn previously reported, John Watson, a member of the WHO Joint Expert Group on Novel Coronavirus Traction Research, was interviewed by foreign media on the 14th. When asked if he was sure that the virus appeared in China, Watson said no.
He says there are many hypotheses about the origin of the virus, with the most likely one being that it spread to humans through intermediate animal hosts.
“China is a very likely source of the outbreak, but the transmission of the virus from animals to humans does not necessarily take place in China,” he said.
He believes that it is also necessary to carry out traceability research outside China.
Hua Chunying asked the United States about the third question on tracing the source of the virus
According to the Xinhua News Agency, in view of the questions such as the United States national security affairs assistant to the President who international panel in China virus traceability the independence of the study, the foreign ministry spokesman said HuaChunYing 18, said individual western politicians keep independence, but independence is not equal to take orders from the west, is not equal to presumption of guilt to China, can produce only respect science, based on the fact that the independent report, scientific conclusions.
There are now more and more reports in the international media that the virus and the epidemic had already emerged in many places around the world in the second half of 2019.
In March 2020, the director of the U.S. Centers for Disease Control and Prevention publicly acknowledged that some of the fall 2019 flu deaths in the United States may actually have been infected with Covid-19.
Antibodies against Novel Coronavirus have also been reported to have been present in blood samples from some Americans in December 2019.
“Can the US side provide all the relevant raw data?
Can the United States cooperate fully with the WHO?
Can the US invite WHO experts to visit the US to trace the source and draw independent conclusions?”
China has conducted in-depth, professional and scientific cooperation with WHO experts in an open and transparent manner, Hua said.
China hopes that relevant countries will also adopt a positive scientific and cooperative attitude, carry out global virus tracing, share and exchange research results, and jointly shoulder due responsibilities and obligations for international anti-epidemic cooperation and the building of a human health community.
