Gastrointestinal infections

Gastrointestinal infections occur when harmful germs like bacteria, viruses, or parasites invade the digestive system, causing symptoms such as diarrhea, nausea, vomiting, stomach pain, and sometimes fever. These infections can spread through contaminated food, water, or contact with infected individuals. They are common worldwide and can range from mild to severe. Good hygiene, safe food practices, and clean water are key to prevention. Most infections resolve on their own, but severe cases may require medical treatment to prevent dehydration and complications.
