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.
Another example; mammals probably developed pregnancy using an Autoimmune virus' genes in the placenta to prevent the fetus from being destroyed by the immune system.
That’s why I always carry a small bottle of isopropyl alcohol as my hand sanitizer. It’s also great that my local grocery store has sanitary wipes right beside the carts so you can wipe down the handle before using it.
