Ten times as many people in Wuhan, China, may have had COVID-19 as has been confirmed, China s Center for Disease Control and Prevention has said.
The CDC posted the results of an antibody study of 34,000 people from Wuhan on WeChat on Monday. It is unclear whether the study has been peer reviewed.
The study, conducted in April, found that 4.4% of those sampled in the city of 11 million people had coronavirus antibodies.
As of Monday, there had been 50,354 confirmed cases of COVID-19 in Wuhan, but the study suggests the real number could be higher than 480,000.
China has been accused of covering up the extent of its outbreak and has silenced journalists and doctors who have spoken out.
