What Does and Doesn't Make the Coronavirus Problem Worse

Things we have reason to believe can spread COVID-19:

1. Airlines.
2. Subways.
3. Cool weather (5–11°C).
4. Lack of UV.
5. Large institutions (schools, prisons, nursing homes).
6. Large celebrations allowed by stupid mayors.
7. Lack of masks.
8. Languages with lots of vowels.

Things we have reason to believe that do not increase COVID-19 deaths:

1. Parks.
2. Beaches.
3. Walkable neighborhoods.
4. Ventilator shortages.
5. Global trade.

We still don't know if mandatory lockdowns are needed. We have reason to believe people were social-distancing themselves anyway. (This also implies that ending such lockdowns won't revive the economy.)
