“We have a number of reports from countries who are doing very detailed contact tracing. They’re following asymptomatic cases, they’re following contacts, and they’re not finding secondary transmission … it’s very rare, and much of that is not published in the literature,” Van Kerkhove(WHO)
Most recently, a study5 in Nature Communications assessed the risk posed by asymptomatic people by looking at the data from a mass screening program in Wuhan, China.
The city had been under strict lockdown between January 23 and April 8, 2020. Between May 14 and June 1, 2020, 9,899,828 residents of Wuhan city over the age of 6 underwent PCR testing. In all, 92.9% of the entire city population participated in the testing. Of these, 9,865,404 had no previous diagnosis of COVID-19 and 34,424 were recovered COVID-19 patients.
Not a single one of the 1,174 people who had been in close contact with an asymptomatic individual tested positive.
In all, there were zero symptomatic cases and only 300 asymptomatic cases detected. (The overall detection rate was 0.3 per 10,000.) Importantly, not a single one of the 1,174 people who had been in close contact with an asymptomatic individual tested positive.
Additionally, of the 34,424 participants with a history of COVID-19, 107 individuals (0.310%) tested positive again, but none were symptomatic.
