Gastrointestinal infections refer to diseases that affect the digestive system, including the stomach and intestines. They occur when harmful bacteria, viruses, or parasites enter the body through contaminated food, water, or contact with infected individuals. This can cause symptoms such as stomach pain, nausea, diarrhea, and vomiting. These infections are commonly referred to as "stomach bugs" and can be contagious, so it's important to practice good hygiene and avoid eating or drinking contaminated substances.
