Q&A with an epidemiologist about the newest coronavirus discoveries

What is the evidence that the coronavirus can linger in the air? Does the ventilation in a room affect transmission? What are the safest and least safe ways to reopen schools? If you could do one thing to make the country safer, what would that be? We took these questions and many more to Dr. Krys Johnson, Assistant Professor in the Department of Epidemiology and Biostatistics at Temple University, for an in depth conversation about COVID-19, what scientists have learned recently, and how we're doing at fighting the virus.
