Research Questions for Aerosol Scientists Addressing COVID-19 and the Workplace

  The Coronavirus Disease 2019 (COVID-19) pandemic has raised many questions about the transmission of the virus that causes COVID-19, SARS-CoV-2, including the possibility of aerosol transmission. In the workplace, workers may encounter asymptomatic, pre-symptomatic, and symptomatic individuals who are infected with SARS-CoV-2 and may expel airborne particles containing the virus. Aerosol scientists bring a Read More >
