Infections Revenge

Many different types of bacteria and parasites also can cause GI infections and diarrhea. Most are not serious and go away after a few days, but others can be quite serious. These symptoms typically last for a few days or longer.

Call your doctor if you think that you have chronic diarrhea or if you see blood in your stool. The incubation period for a gastrointestinal infection depends on the particular germ causing it. For example, the Shigella incubation period is usually 2 to 4 days, but the period for viral infections ranges from 4 to 48 hours.

Then, depending on the type of germ and the person's overall health, a diarrheal infection can last for a few days or a few weeks. Diarrheal infections are highly contagious. They can spread from person to person via dirty hands, contaminated food or water, and some pets. Most cases are contagious for as long as a person has diarrhea, but some infections can be contagious for even longer. The most effective way to prevent contagious diarrheal infections is to wash your hands well and often.

Dirty hands carry germs into the body when you do things like bite your nails or use your hands when eating. It's important to always wash your hands with soap and water thoroughly after using the bathroom and before eating, especially if you know there's an illness going around. Making sure your bathroom surfaces are clean can also help to prevent infections. Food and water can spread germs that cause diarrhea. To help protect yourself, cook foods thoroughly and wash raw fruits and vegetables well before eating them. Avoid eating pink hamburgers or other undercooked meat, and always refrigerate leftovers quickly — your delicious turkey dinner can grow nasty bacteria after just a few hours of sitting on the counter.

Make sure your kitchen counters and cooking utensils are clean, too, especially after they've been in contact with raw meat, eggs, and poultry. Avoid eating food that's been left out for a few hours, even if it's been reheated, because toxins can still survive in the food. If you're traveling or camping, never drink from streams, springs, or lakes unless local health authorities have certified the water safe for drinking.

In some developing countries, you may want to stick to bottled water and drinks rather than tap water — and be careful about buying food from street vendors. Pets, particularly reptiles, can spread germs if they aren't kept away from family eating areas.

Avoid washing pet cages or bowls in the same sink that your family uses to prepare meals. And always wash your hands after handling your pet! Sometimes, despite your best efforts, you can't prevent diarrheal infections. Tell an adult if you have diarrhea, fever, vomiting, or severe abdominal pain. That person can help you decide whether to call your doctor.
