Human intestinal infection
Human intestinal infection occurs when harmful microorganisms like bacteria, viruses, or parasites invade the digestive system, causing symptoms such as diarrhea, stomach pain, nausea, and vomiting. These infections often result from contaminated food or water, poor hygiene, or close contact with infected individuals. They can vary in severity, from mild discomfort to serious illnesses, and may sometimes lead to dehydration or more severe complications if not properly managed. Good hygiene, safe food practices, and clean water are essential for prevention. Most infections resolve with appropriate treatment and supportive care, although some may require medical intervention.
