Coronavirus stays suspended in the air for hours. UVC disinfection affects those suspended articles, which surface cleaning does not.

  >Coronavirus stays suspended in the air for hours. In controlled lab environments. Also, it likely doesn't stay in loads high enough to cause infection. Any airborne virus will be affected by volume displacement, air currents, air exchanges in addition to things like UV light from the sun, humidity and temperature changes. If I were asked to pick a disinfection method, I would not take disinfecting the air into my consideration.

    There’s some evidence it happens in the real world too. In the very early days of the pandemic first there was a case in China where an infected but asymptomatic person went to church and sat in a pew. That person left the church and a different person who later sat in the same spot became infected.

      That case was mentioned in a popular paper with about 8 others I recall. One big issue is that they all occured pretty early on when testing wasn't so wide spread. So there's also a good chance it was just a concidence and they were actually exposed to someone else. This is one issue with the media. That paper, with less than 10 case reports of asymptomatic and potential airborne spread was spread much more rapidly than the WHO report which reviewed ~70k Chinese cases and most spread within household contacts.
