Stomach flu (or viral gastroenteritis) is an abdominal infection marked by stomach cramps, watery diarrhea, vomiting or nausea, and sometimes even fever.
The most common way to develop stomach flu (viral gastroenteritis) is through contact with an infected person or by consuming contaminated food or water.
There are not any complications for otherwise healthy people, but for older adults, people with compromised immune system and infants this disease can be even deadly.
