Covid infected just 6.9% of Wuhan people
The first long-term study of Covid infection rates in Wuhan, China, published recently in The Lancet, has found that in April last year 6.9% of residents in the city — regarded as the epicentre of the pandemic — were infected. About four in five of those infected displayed no symptoms. The research found that 40% of those infected developed neutralising antibodies, and these antibodies were still present more than six months later. The results are published in an observational study of 9,542 people.
