Ironically, I think the prevalence of hand sanitisers has actually led to people washing their hands less. All the sanitisers do is kill viruses, they don't actually get dirt and grime off your hands like soap would do. Yet people sometimes seem to use them in place of soap now. They'll go to the loo and just use sanitiser afterwards, rather than actually washing their hands. There's just no substitute for good old soap and water. Given a choice between eating a meal with hands that might have been in contact with a virus, or eating a meal with hands that might be covered with dirt, I'd take my chance with using the virus hands over the dirt hands any day.
