Jessica Justman, MD, ICAP’s senior technical director, is quoted in a June 9 Newsday article on the potential for asymptomatic spread of COVID-19.
Dr. Jessica Justman, an associate professor of medicine in epidemiology at Columbia University’s Mailman School of Public Health, said although it’s clear that asymptomatic people spread the virus, “the jury is still out” on how important a factor they are.
“Are they accounting for 5% of new infections or 50% of new infections?” she asked. “It’s not so clear.”
Studies have come to different conclusions because of variations in methodology, and more research is needed on the topic, she said.
Even so, Justman said, “It behooves us to assume it’s an important factor” and for people to continue to wear masks and practice social distancing.
