Indoor Air Changes and Potential Implications for SARS-CoV-2 Transmission

By / / Leave a Comment

Buildings have been associated with spread of infectious diseases, such as outbreaks of measles, influenza, and Legionella. With SARS-CoV-2, the majority of outbreaks involving 3 or more people have been linked with time spent indoors, and evidence confirms that far-field airborne transmission (defined as within-room but beyond 6 feet) of SARS-CoV-2 is occurring. Controlling concentrations […]

It’s not just the mask, it’s the humidity created inside the mask that helps protect against severe COVID-19, a recent study by National Institutes of Health (NIH) researchers suggests. The use of cloth masks has been linked with decreased disease severity, which is sur- prising considering such masks aren’t good at filtering out the smallest
