A mathematical model estimates that 59% of all transmission of SARS-CoV-2 comes from asymptomatic cases, suggesting that strategies based on identifying and isolating symptomatic people will not control the pandemic. The model estimates that 35% of SARS-CoV-2 transmission comes from presymptomatic individuals and 24% from individuals who never become symptomatic.
