Infectious diarrhea, or gastroenteritis, is caused by a bacterial or viral infection. It is typically transmitted through contaminated food or water and can lead to the sudden onset of symptoms such as diarrhea, nausea, and abdominal cramps.

Some types of bacteria and viruses that can cause infectious diarrhea include:

Salmonella

Salmonella is commonly found in raw or undercooked poultry, eggs, and meat. It can also be found in unpasteurized dairy products and contaminated water.

E. coli

E. coli is found in the feces of animals and humans and can be transmitted through contaminated food or water. It can also be transmitted through person-to-person contact.

Norovirus

Norovirus is a highly contagious virus that is a common cause of gastroenteritis. It is transmitted through contaminated food or water and can also be transmitted through person-to-person contact.

Rotavirus

Rotavirus is a common virus that affects children and is a leading cause of diarrhea in infants and young children. It is transmitted through contaminated food, water, and hands.

Infectious diarrhea caused by bacteria is more likely to be severe and lead to complications, such as dehydration, than diarrhea caused by a virus. The severity of infectious diarrhea can vary greatly and depends on the specific bacteria or virus and the individual’s underlying health status.

If you are experiencing severe diarrhea or other symptoms, it is important to seek medical attention.
