Most viruses actually have direct transmission, for example, sneezing and holding hands without washing them. In restaurants, food handlers and staffer have strict instructions to “wash as they go” especially when they are in the bathroom. Most of them even have posters that have instructions on how to wash hands properly. That is why there are automatic hand dryers in their toilets as well as they do not need to touch anything inside the bathroom after they have washed their hands. This is actually a good practice to do at home too.
