Infectious gastroenteritis is a general term for gastroenteritis caused by pathogens such as bacteria and viruses.

Infectious gastroenteritis occurs year-round, but is most prevalent in the fall and winter. In particular, norovirus is highly contagious, and large-scale epidemics can occur in places where people live in groups, such as schools and social welfare facilities.
The most important preventive measure is to wash your hands. Wash your hands thoroughly with soap and running water, especially after defecation and before cooking or eating. Also, wear disposable gloves, a mask, and an apron when handling feces and vomit, and wash your hands thoroughly with soap and running water after handling. When cooking bivalves such as oysters, heat them well through the center. (The center temperature must be heated to 85°C for 1 minute or more.)
