Given we now know COVID-19 is airborne and even the WHO has accepted that with a long “airborne risk assessment” for COVID-19 (*), the world is slowly pivoting toward engineering to reduce airborne disease transmission. In March 2024, after the publication of the WHO document, 33 professors and PhDs pushed for a policy change in an article on Science.org: Mandating indoor air quality for public buildings.
Know that other diseases are airborne too: Measles (studies 1 2 3 4), Influenza, RSV, and TB. The same ventilation and air filtration measures reduce transmission of those too.
