UPI: Face Masks as COVID-19 Prevention

United Press International news service interviewed SPH's Dr. Mark Dworkin, professor of epidemiology, on the use of facemasks to prevent the spread of COVID-19.  Dworkin noted that while the science behind mass mask usage is unproven, the concept that apply to medical professionals wearing a surgical mask could apply to COVID-19 transmission.

We don’t know how effective wearing a mouth and nose covering like a bandana or mask is for COVID-19, but it has what we call ‘biological plausibility.’
