Right now PRC is in full force to spin the source of virus from themselves to USA, including withdraw their previous claims.
There is a famous HK professor Yuen Kwok Yung, leading the fighting against virus since SARS in 2003, has a signed article in local press ming pao with English extract below
https://news.rthk.hk/rthk/en/component/k2/1515264-20200318.htm. Two top Hong Kong University microbiologists on Wednesday said it is easier for people to remember the coronavirus as the "Wuhan virus" and slammed the culture of wild meat consumption on the mainland, saying mainlanders have forgotten the bitter lessons of the 2003 Sars outbreak.
In an article in the Chinese-language newspaper Ming Pao co-written by Yuen Kwok-yung and his colleague David Lung, the microbiologists said that the current coronavirus pandemic originated from the mainland city of Wuhan.
They called on people to stop forwarding rumours that the virus originated in the US, saying this is baseless and a joke.
On a controversy over names for the virus, the experts wrote they think it is “simple and direct” to call it "Wuhan coronavirus" or "Wuhan pneumonia".
They said the disease was named Covid-19 because the World Health Organisation stopped using names of people or places from 2015.
“While scientists should use Covid-19 during academic exchanges, it is easy for communication for ordinary people and the media to call it Wuhan virus or Wuhan pneumonia,” they wrote.
They also warned there would be "Sars 3.0" if people on the mainland do not stop eating wild animals.
“It’s a serious mistake that tough measures were not taken and game meat markets were not closed after the Sars outbreak. One must face the truth and avoid the same mistake again to fight the pandemic. Don’t blame it on others,” they wrote.
They reminded people that the Sars outbreak was linked to viruses that came from civet cats.
“It’s been seventeen years. Markets selling game meat are not banned. The problem has become more serious. Mainland people have completely forgotten the lesson from the Sars outbreak. It is eyebrow-raising that there are game meat markets in the middle of developed cities, and people openly sell, cook and eat them,” the article said.
It said mainland people's disrespect for animals was the source of this virus outbreak.
And just an hour ago, professor Yuen decides to retreat this article, admitting he is not a political awared person.
The fact is after the publish the propaganda and the mainland China netizens has scolded a lot and think professor Yuen, a supposedly friendly people to government, is anti-partriotic and stand aside Donald Trump and America.
So watch out, besides the real corona virus, there are some other consequences in the way. How Beijing government user their resources to affect the American election, should be examined on the microscope.
