Asymptomatic Transfer: The Science

All known science says Asymptomatic Transfer is so rare it is statistically irrelevant. Here is the science.

Wuhan tests 10 Million people, finds only 300 asymptomatic coronavirus infections.

Officials said the asymptomatic carriers were determined to not be infectious — adding that masks, toothbrushes, phones, door handles and elevator buttons that they touched had no traces of virus. https://pubmed.ncbi.nlm.nih.gov/33219229/

University of Florida researchers find no asymptomatic or presymptomatic spread.

Four researchers from the University of Florida Department of Biostatistics co-authored a study published online by the Journal of the American Medical Association.

Coronavirus spread by asymptomatic people ‘appears to be rare,’ WHO official says

The spread of Covid-19 by someone who is not showing symptoms appears to be rare, Maria Van Kerkhove, the World Health Organization’s technical lead for coronavirus response and head of the emerging diseases and zoonoses unit, said during a media briefing in Geneva on Monday.

CDC estimates that 35% of coronavirus patients don’t have symptoms. “From the data we have, it still seems to be very rare that an asymptomatic person actually transmits onward to a secondary individual,” Van Kerkhove said 

Anthony Fauci: Asymptomatic transmission never drives outbreaks

‘In all the history of respiratory-borne viruses of any type, asymptomatic transmission has never been the driver of outbreaks.’

World Health Organization Emerging Diseases and Zoonosis Unit head Maria Van Kerkhove said coronavirus transmission by people who aren’t showing symptoms is “Very rare.”
