Norovirus, sometimes referred to as the winter vomiting bug, is the most common cause of gastroenteritis.
In adults, norovirus and Campylobacter are common causes.

The virus is usually spread by the fecal–oral route.
Norovirus and rotavirus, common causes of viral gastroenteritis, are transmitted by the faecal–oral route and are passed from person to person by contact, entering the body in food or water.

Diarrhea

Infection is characterized by diarrhea, vomiting, and stomach pain. Norovirus infection is characterized by nausea, vomiting, watery diarrhea, abdominal pain, and in some cases, loss of taste.

Hand sanitizer

alcohol based hand rubAlcohol rubalcohol rubs
Alcohol-based hand sanitizers are less effective.
There are certain situations during which hand washing with water and soap are preferred over hand sanitizer, these include: eliminating bacterial spores of Clostridioides difficile, parasites such as Cryptosporidium, and certain viruses like norovirus depending on the concentration of alcohol in the sanitizer (95% alcohol was seen to be most effective in eliminating most viruses).
