Has there been any significant progress for making indoor spaces safer by treating air? While spring and summer will alleviate some of the risk by having people outdoors more, there are still places like gyms, grocery stores, etc. that are indoors. I'm fully vaccinated, but the particular idea of going back to my weightlifting gym seems slightly risky to me, mostly from the thought of being indoors where people are heavily breathing (I'm not concerned about touching equipment... that can be sanitized and I can wash my hands).
This is in a community that controlled community spread and proved it with testing and contact tracing so I was confident that very few people would go to the gym with the virus and the physical barriers and distance and now the vaccine are a reason not to fear.
I'm just glad that they were able to stop forcibly ventilating people. They never admitted a mistake, there; but they killed some people in a particularly nightmarish way with those.
