Asymptomatic spread of coronavirus ‘Very Rare’: WHO

Asymptomatic spread of coronavirus 'Very Rare': WHO

The World Health Organization says that transmission of Covid-19 by asymptomatic carriers is “very rare.” The head of its emerging diseases and zoonosis unit, Maria Van Kerkhove, said during a media briefing in Geneva on Monday.

“From the data we have, it still seems to be rare that an asymptomatic person actually transmits onward to a secondary individual,” Van Kerkhove said.

“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 onward. It is very rare – and much of that is not published in the literature,” she said. “We are constantly looking at this data and we’re trying to get more information from countries to truly answer this question. It still appears to be rare that an asymptomatic individual actually transmits onward.”
