COVID-19 Warning: Humid Air Can Extend Lifetime of Virus-Laden Aerosol Droplets
Scientists report a detailed model of aerosol transport through air, considering several environmental conditions, such as temperature, humidity and ambient flow. The novel coronavirus that causes COVID-19 is thought to spread through natural respiratory activities, such as breathing, talking, and coughing, but little is known about how the virus is transported through the air.
