COVID-19 is an airborne disease - so the better your ventilation, the lower your risk.

Why it still matters

  • COVID-19 is transmitted by aerosols. (AKA it’s airborne.)

    Aerosols are extremely small, light micro-droplets that can float in the air for a long time. Lots of research over the past year has shown that the coronavirus can be transmitted by these tiny particles.

    Interested in learning more about how these droplets can cause infection? This post from First10EM explains this kind of COVID-19 transmission happens, and includes links to related studies.

  • We can decrease the amount of virus indoors by bringing in outside air

    The fewer virus particles there are in the air around us, the less likely we are to become infected. As this article from the EPA explains, the more people there are in an indoor space, the more important it becomes to bring in plenty of (clean) outdoor air.
  • Even if we can’t bring in outdoor air, we can clean the indoor air.

    Sometimes it’s just not possible to bring lots of outdoor air inside. In those cases, as the CDC notes here, cleaning the indoor air is the best option. It’s critical to use technology that is proven to work (HEPA filters or UVGI units) and avoids introducing anything else harmful to the air.

How to do it

  • Short- and medium-term solutions

    What you can do right now will depend on your budget, your building, your surrounding environment, and, most importantly, the needs of folks in your school(s).
  • Long-term solutions

    Many schools have needed significant ventilation upgrades for decades. With billions of dollars available from the federal government for COVID-19 mitigation, now is the time to think, plan, and implement those long-term solutions! (Just don’t forget to account for ongoing maintenance costs.)
