Dysentery is infection and inflammation of the intestines, which causes diarrhea that may contain blood or mucus. Other possible symptoms include abdominal pain, nausea and vomiting, and fever. Dysentery can occur as a result of bacterial or parasitic infections. Dysentery outbreaks are more common in countries with hot, moist climates and poor sanitation. A person can help prevent dysentery by taking appropriate precautions when traveling to high-risk areas and practicing good hygiene. In the U.S., most cases of dysentery are mild and do not require treatment. However, people who experience severe symptoms should see their doctor for a diagnosis and appropriate treatment. Doing so reduces the risk of possible complications. (责任编辑：) |
