Asymptomatic persons can spread SARS-CoV-2 infections to others.
Is it true that asymptomatic persons can spread SARS-CoV-2 infections to others?
Yes. Extensive empirical and systematic review evidence confirms that asymptomatic and presymptomatic individuals can and do transmit SARS-CoV-2 infections to others.
Verdict: SUPPORTED · 4 sources for, 0 against · Last checked
The retrieved papers, including systematic reviews and quantitative analyses of viral dynamics, consistently support the scientific consensus that SARS-CoV-2 can be spread by individuals who display no symptoms. None of the papers refute this claim.
