For example, enteritis caused by viral, bacterial, or parasitic infections is usually a risk of infection and is transmitted mainly by the fecal-oral route, while the rest of enteritis, including enteritis caused by the ingestion of chemical toxins or drugs, has no basis for transmission. The population at risk for enteritis includes children <2 years of age, immunocompromised individuals, immunocompromised elderly people, and patients with a history of oral antibiotics in the last 3 months. To prevent infection, good hygiene practices and active treatment are required. Wash your hands frequently, and regularly clean and disinfect dishes that hold meals, refrigerators, as well as chopping boards and knives. To prevent water-related infections in recreational facilities, do not swim when you have diarrhea. For patients with enteritis, in addition to the need to prevent infection, they should also pay attention to good habits, pay attention to rest, avoid staying up late, quit smoking and drinking, avoid drinking strong tea and coffee, and avoid eating greasy and spicy stimulating food. Drink more water to avoid dehydration.
