Can special lightbulbs end the next pandemic before it starts?

Ultraviolet light can kill almost all the viruses in a room. Why isn’t it everywhere?::Can special lightbulbs end the next pandemic before it starts?

    This is the most informed comment in the thread where it’s clear you actually read the damn article.

    Some of this does appear to be due to a widespread misunderstanding about how droplets spread disease in the medical field. It was thought that UV light far enough away to be safe would also be too far away to be effective. At least, not without additional ventilation, but ventilation itself would help reduce the spread, and we don’t do that because it’s expensive. UV would be cheap.

    Research conducted during Covid corrected this scientific misunderstanding, and UV may be effective without additional ventilation. Ozone effects still need to be studied, though, as well as overall effectiveness. It might be that the additional ozone causes a few hundred additional deaths, but with the tradeoff of thousands or even millions fewer respiratory disease deaths. That would be a worthwhile tradeoff, but we don’t know what those numbers look like.

      I can’t really blame people for not reading it, They take a long time to get to the point and they’re not very cohesive even once they get there.

      I just read an NIH meta study on ozone and covid about half the studies aren’t very useful, as is always the case with meta studies. It seems, at least with the variant they tested that the virus is not particularly susceptible to oxidation. The one study did note that it slightly lowered It’s ability to infect which may be useful.

      Thing is, ozone’s pretty rough even on healthy lungs. I think the main worry is cancer risk over time which is a real bummer.

      It’s hard because we’re absolutely walking germ factors and anything strong enough to truly knock out the germs is strong enough to damage us over time.

      I wonder is in 100 years will have robots in stores walking around behind us sterilizing everything we touch.
