Ah! What a fascinating world. The parts of the US that I am familiar with make extremely widespread use of indoor climate control. Many buildings, such as offices and schools, have windows that barely open or don't open at all. And even if the weather permits you to eat outdoors, there usually isn't enough public space where you could do it comfortably and safely. I guess you could drive to a restaurant and then eat in your car with the windows rolled down.
- graeme 6y agoNotably the US had high summer covid cases in the AC belt, in contrast to the northeast and also in contrast to canada and europe, where hermetically sealed environments are less common. I’d be curious to know what flu and cold season is like in the south. There may also be seasonal changes to hvac systems in milder climates. They all have varying degrees of recirculation vs bringing in outside air. If you are running heavy ac or heavy heating, it costs more to bring in outside air. So there may be seasonal variations in recirculation settings even within the same sealed environment. I’m less confident on this point though as I don’t know hvac’s very well and they are supposed to filter viruses.
