Daniel P. Oran, Eric J. Topol. The Proportion of SARS-CoV-2 Infections That Are Asymptomatic. A Systematic Review. Ann Intern Med. 2021 online
Available data suggest that at least one third of SARS-CoV-2 infections are asymptomatic …
In light of the data presented here, we believe that COVID-19 control strategies must be altered, taking into account the prevalence and transmission risk of asymptomatic SARS-CoV-2 infection. Frequent, inexpensive, rapid home tests to identify and contain presymptomatic or asymptomatic cases—along with government programs that provide financial assistance and, if necessary, housing to enable infected persons to isolate themselves —may be a viable option. And as the first generation of SARS-CoV-2 vaccines is deployed, more research will be needed to determine their efficacy in preventing asymptomatic infection
