On June 9, 2020 Dr Maria Van Kerkhove, head of the World Health Organization’s emerging diseases and zoonosis unit, said transmission of the coronavirus by people who aren’t showing symptoms (asymptomatic) is “very rare“, then backtracks, “much is still unknown“! [2]

Modelling studies estimate as many as  40% of “infections” could be transmitted by people “who have the virus [PCR positive!] but no symptoms”. [1]
