Gastrointestinal infections are viral, bacterial or parasitic infections that cause gastroenteritis, an inflammation of the gastrointestinal tract involving both the stomach and the small intestine. Gastrointestinal infections can be caused by a large number of microorganisms, include Yersinia enterocolitica. staphylococcus aureus, salmonella and shigella, rotavirus, helicobacter pylori, escherichia coli, clostridium difficile, campylobacter, adenovirus. Symptoms include diarrhea, vomiting, and abdominal pain. Dehydration is the main danger of gastrointestinal infections, so rehydration is important, but most gastrointestinal infections are self-limited and resolve within a few days. However, in a healthcare setting and in specific populations such as newborns, infants, immunocompromized patients or elderly populations, they are potentially serious. Rapid diagnosis, appropriate treatment and infection control measures are therefore particularly important in these contexts. This session discusses more about gastrointestinal infections.
