Covid-19: four fifths of cases are asymptomatic, China figures indicate

Covid-19: four fifths of cases are asymptomatic, China figures indicate, by Michael Day, in the BMJ medical publisher.

New evidence has emerged from China indicating that the large majority of coronavirus infections do not result in symptoms.

Chinese authorities began publishing daily figures on 1 April on the number of new coronavirus cases that are asymptomatic, with the first day’s figures suggesting that around four in five coronavirus infections caused no illness. Many experts believe that unnoticed, asymptomatic cases of coronavirus infection could be an important source of contagion.

A total of 130 of 166 new infections (78%) identified in the 24 hours to the afternoon of Wednesday 1 April were asymptomatic, said China’s National Health Commission. And most of the 36 cases in which patients showed symptoms involved arrivals from overseas, down from 48 the previous day, the commission said.

Tom Jefferson, an epidemiologist and honorary research fellow at the Centre for Evidence-Based Medicine at the University of Oxford, said the findings were “very, very important.” He told The BMJ, “The sample is small, and more data will become available. Also, it’s not clear exactly how these cases were identified.”

Apart from the small size of the sample (hundreds of thousands of cases in China, and their sample size is so small?), a major problem is that the sample is from China.

China has been “making mistakes” (such as scaring 5 million people from Wuhan into traveling to all corners of the globe just before lockdown) or lying about this virus (it’s just like the flu, said their sock-puppet at the WHO)  from the get-go. The “mistakes” all have something in common — they help spread the virus to and within the West.

It’s as if China wants the West to get sick, to let down our defenses. And some in the West propagate China’s lies without the proper skepticism.
