Smoke particles are larger than those of S ARS-CoV-2 , the virus that causes COVID-19, so masks do not work . Smoke from wildfires is a complex mixture. The World Health Organization changed its guidance due to new evidence that the virus may be airborne longer in tiny viral particles, which poses greater risk in poorly ventilated spaces. This shows a lack of understanding. Neutrinos interact very weakly with matter and are the second most abundant particle after photons (which behave more like waves than actual particles). They are colorless in a more fundamental way . More knowledge has come out, most recently in a journal called Lancet, that looked at numerous studies that showed masks reduce our risk to COVID-19.
