For anyone who needs to be extra cautious not to get infected with #SARS-CoV-2, I found the calculator below helpful.
This project will end before the middle of March, sadly, but I hope the calculator will still be available.

One thing I found off with the calculator was their 'risk budget' -- their highest category is 10% per year, yet most Americans are probably operating at 30-50% per year and my suspicion is that even very cautious households will only get down to about 10% per year. Their pre-defined scenarios don't include things like classrooms, offices, or dormitories. I tried to estimate the situation in my kid's classroom, and found that simply being in the classroom (fully vaccinated; KN95 mask) it gave them about 4% chance of getting covid over the year. And that did not account for indoor lunch, indoor gym class, pep rallies, etc.
@DecaturNature You are right. It has its limits.
For me it was a useful tool, but only combined with a CO2 meter for any type of indoor activity, such as visiting primary care or specialist visits.
@Tatiana_Trifan When The calculator also does not seem to let me calculate risk from members of my household - there's a setting for a 'live in partner', but not for a 4-member household. The categories for the partner's risk were also insufficient -- for some reason the "harm reduction budget" (2000 mC) was not included, and the person with 4 close contacts was given a higher infection rate than 'average person', implying that the average person has fewer than 4 close contacts. The calculator is a nice start, but quickly runs into limits that stop it from being useful to most people. It's a shame that we don't have anything better... but thanks for sharing it anyway.
