Burton Singer of UF has found that asymptomatic individuals account for 35% of COVID-19 cases. Singer analyzed over 350 studies to arrive at this estimate, which highlights the role asymptomatic people play in transmitting the virus.

“And by asymptomatic, we mean truly without symptoms over the course of the course of their infection,” said Singer. “This is different than people who may not have symptoms when they get tested, test positive, and then later develop symptoms.”
