Shirlee Wohl, Ph.D., postdoctoral researcher at the Johns Hopkins Bloomberg School of Public Health, explains how viral variants are identified, why her work tracking them is so important and what new types of SARS-CoV-2 could mean for the end of the pandemic.

“The one thing people ask me most is should I be more scared?” says Wohl. “Instead, I suggest that new, more infectious COVID-19 variants make the safety measures we already are taking even more important.”

Wohl is available for interviews on this topic.
