Did half a million people in Wuhan contract the coronavirus?

Over 4 per cent of the 11 million people in the central Chinese city of Wuhan might have been exposed to the coronavirus that causes Covid-19, according to a national study of blood antibodies.

The results from the first large-scale survey of its kind in the country indicated that 4.43 per cent of the city’s residents had antibodies for the virus, a standard measure of past infection.

While various factors, including uneven distribution of infections within a population, make it difficult to pinpoint how many people were infected, the findings suggest that roughly half a million people in the city may have contracted the virus during the initial outbreak.

That total is 10 times the 50,008 people officially recorded by mid-April in Wuhan, where a flood of infections overwhelmed the city’s health system in the weeks after the virus was first identified late last year.
