Bacteria, toxins or parasites may cause the onset of gastroenteritis: inflammation in the stomach and intestines.
Norovirus infections (a group of related viruses) are what cause gastroenteritis. People become infected by this disease through drinking non-potable water or eating contaminated food. It can also be transmitted from touching an infected surface. This condition requires special treatment for young children and older adults, but in most cases, it goes away on its own.
As the MedlinePlus webpage indicates, the most common symptoms of gastroenteritis are diarrhea, nausea, vomiting, abdominal pain, fever, headache or malaise. Treatment includes rest and drinking fluids to prevent dehydration. Guidelines for prevention include washing your hands properly and washing your vegetables, fruits, meats, and other ingredients, when cooking them.
Keep in mind
The bacteria that most cause diarrhea in developed countries are salmonella and campylobacter. In most cases, both infections are transmitted from consuming poorly cooked chicken and unpasteurized milk. In some cases, campylobacter is transmitted through dogs or cats that have diarrhea. Salmonella is transmitted by ingesting raw or partially uncooked eggs, or through contact with reptiles (such as turtles or lizards), birds, or amphibians (such as frogs and salamanders).
