Coronavirus has spread to Finland.
Hopefully it won't survive saunas/alcohol.
Bad news there. Viruses are tough as shit. Only UV-C radiation is quite effective at killing germs, bacteria and viruses (and all animals and humans, with enough watts per square centimeter of exposed skin, over exposure time).
I read that alcohol kills it, and temperatures above 57 degrees C.
Not corona viruses, afaik.
Best source i found on a quick search:
https://thehill.com/changing-america/well-being/prevention-cures/480245-fda-tells-purell-that-its-products-cant-treat-orHigh temperatures kill viruses, correct. But you need exposed viruses and for a longer time. UVC kills within seconds with a quartz lamp of 30w quoted power and a distance of a few centimeters. If a human could survive a raised core temperature of 60° celsius for an hour, this would be an easy cure. But that isn't the case.
The problem is, the virus is carried in a life supporting environment, the body, and spread by attaching to drops (mucosa) and skin particles outside.
EDIT: The tradeoff of using UVC on the human skin is that it does way more harm to viruses (and bacteria) in a short exposure time than to the human skin, but it's still dangerous. Not many lamps out there that suppress ozone generation, too. One has to research a lot about the safe usage of these lamps before he knows how to avoid endangering human health with them.
A low power directional uvc light source above any door in public areas, directed at the handle from above, would be a huge help in exposition prophylaxe. I saw these hanging over the counters of some fast food restaurants already. Hospitals and airports, all public builings could benefit from that but there's the human affinity to dumbness on the other side of the equation. Putting on masks and feeling safe...
