It is an inflammation of the inner layer or mucosa of the intestine caused by an infection.
It is usually caused by a virus (norovirus, rotavirus, adenovirus and astrovirus) although it can be bacterial or parasitic. The germs are contracted after ingesting contaminated food or water.
It manifests with nausea and vomiting, diarrhea, abdominal pain, headache, malaise, fever and chills.
Diagnosis is made by questioning and physical examination; blood and stool tests may be necessary to study the severity and causative agent of the clinical picture.
It is usually a self-limiting disease with no need for treatment. If necessary, symptomatic treatment should be carried out and proper hydration should be ensured. Antiemetics may be added for vomiting.
