A top Chinese health official sought to allay growing fears over asymptomatic coronavirus carriers on Monday, saying there was “no evidence” they could spread the illness but medical workers should remain alert to the risk.

Lu Jinxing, from the Chinese Centre for Disease Control and Prevention (CDC), made the remarks in an interview with state broadcaster CCTV amid rising public concern over people who contract the virus but show no immediate symptoms – a condition typically known as asymptomatic.

It is still not clear what role asymptomatic transmission is playing in the global pandemic. But the South China Morning Post reported earlier that as many as one-third of those who test positive could be “silent carriers” with delayed or no symptoms.

Classified government data seen by the Post showed more than 43,000 people in China had tested positive for Covid-19 by the end of February but had no immediate symptoms. They were quarantined but not included in the official tally of confirmed cases.

Lu told the state broadcaster: “We have observed a great number of asymptomatic cases and found that people had a relatively long duration of viral shedding,” referring to the rate at which an infected person “sheds” the virus.
