True! Here’s a little additional information since the north is in virus season.

A virus is a protein wrapped in a protective fatty lipid. Heat will melt the fat, then break down the protein. That’s why viruses last longer on surfaces and clothing in the cold season, increasing probability of transmission. A virus can remain intact on a shopping cart handle for up to 24 hours in the winter, for example.

You can also rapidly break down the fatty lipid using isopropyl alcohol, or break down the protein directly using hydrogen peroxide. Be careful using the latter. It can bleach or discolor dyed textiles.

the swedish department of health says the opposite though, that you have to wash your hands with soap to affect at least some viruses.

The WHO says the same. Soap is a surfactant, so the viruses will be mechanically removed from the skin, and flushed away by the water.

My comment was meant to be in regards to sanitizing surfaces. I’m sorry if that was unclear.
