Regular soap is fine. Soap and water are the the best preventatives because there is no need for them to kill anything to be effective. You only need to wash the viruses or bacteria off your hands in order to prevent infection. Just like we wash our vegetables with water and don't get sick - all we have to do is rinse the germs off of them, not douse our veggies in sanitizer.
Soap aids water in removing things off our hands more effectively.
Maybe I'm jaded or callused. People complain constantly that the world is over populated and we're killing off nature. The natural effect of too many humans is that diseases will help limit the population explosions. A 99 year old is going to die of something within a few weeks or months. Some kind of virus or just the body failing is going to cause a death.
I think it should be encouraged that those who are medically fragile, old or immuno-compromised should be encouraged to wear masks, avoid going out in public, etc., and the rest of us should just live with the fact that we are exposed to multitudes of viruses, bacteria and fungi every day, and some of those will make us ill or kill us.
