Gastroenteritis is most frequently caused by a viral infection and is commonly referred to as viral gastroenteritis, the stomach flu, or the 24-hour or 48-hour “bug.” This type of infectious gastroenteritis is contagious.
A bacterial infection, such as Salmonella food poisoning, can cause bacterial gastroenteritis, which is also contagious.
Similar gastrointestinal symptoms can also result from a variety of other conditions that are not contagious, such as alcohol intoxication or irritable bowel syndrome.
Gastroenteritis can lead to serious complications such as dehydration, especially in infants, young children, the elderly, or people with chronic diseases. The underlying disorder, disease or condition that is causing gastroenteritis can also cause complications.
Seek prompt medical care if you have symptoms of gastroenteritis that do not improve after a day or two. Seek immediate medical care ( call 911) if you, your child, or someone you are with, have symptoms of gastroenteritis accompanied by lethargy, change in alertness, delirium, a seizure, rectal bleeding, or a lack of urination.
