The air outside is constantly sterilized by UV light.
Care to taste a spoonful of dirt in a sunny day to see how sterile it is?
At the start of the CoViD pandemic I installed a UV lamp(turned on using a current sensor on the blower fan power wires) in the return air manifold on my furnace. My family still ended up all getting CoViD once one of us got it. But I keep it there because... why not? I'm sure it helps reduce the viral load in the air a bit.

Maybe fewer consequences than you'd think... https://rachel.fast.ai/posts/2024-08-13-crowds-vs-friends/ "Your Immune System is Not a Muscle" > Four main categories of pathogens that humans deal with are viruses, bacteria, fungi, and parasites. The evidence for pathogens that may be beneficial to the immune system is almost entirely for parasitic worms and friendly (commensal) bacteria. In contrast, many viruses can e…

> Studies have shown that various immunological and autoimmune diseases are much less common in the developing world than the industrialized world and that immigrants to the industrialized world from the developing world increasingly develop immunological disorders in relation to the length of time since arrival in the industrialized world.[23] This is true for asthma and other chronic inflammatory disorders.[18] The…
From the same wikipedia page: > The hygiene hypothesis has difficulty explaining why allergic diseases also occur in less affluent regions. Additionally, exposure to some microbial species actually increases future susceptibility to disease instead, as in the case of infection with rhinovirus (the main source of the common cold) which increases the risk of asthma I think having a common cold infection each year does…

I can't wait for a dynomight article about this :D
This line gave me pause: "This happened despite murine norovirus being more resistant to far-UVC than many common human respiratory viruses, likely due to its tough protein outer ‘shell’.". Under wide spread use, would viruses simply mutate to being more resistant to far-UVC?
The outdoor environment has lots of UV rays from the sun, so this selection pressure has existed for a long time.
