Nearly half a million residents in the Chinese city where the novel coronavirus first emerged may have been infected with COVID-19 — almost 10 times its official number of confirmed cases, according to a study by the Chinese Center for Disease Control and Prevention (CDC).
The study used a sample of 34,000 people in the general population in Wuhan — the original epicentre of the pandemic — and other cities in Hubei province, as well as Beijing, Shanghai, and the provinces of Guangdong, Jiangsu, Sichuan and Liaoning to estimate COVID-19 infection rates.
