Microcovid

We created the concept of the "microcovid" as a new quantitative unit for risk. One microCOVID is a one-in-a-million chance of getting COVID-19. An activity that’s 20,000 microCOVIDs means that you have a 2% risk of getting COVID every time you do it. An activity that’s 20 microCOVIDs (or 0.002%) is relatively safe, as you could do it every week for a year and still have only accumulated about a 0.1% chance of getting COVID. https://www.microcovid.org/
