Acute diarrhea starts quickly and lasts a short time, usually 1 to 3 days. It can last up to 2 weeks. Your child may have several loose bowel movements throughout the day. He or she may also have a fever, abdominal pain, nausea and vomiting, and a loss of appetite. Acute diarrhea usually gets better without treatment.

Medicines:

• Medicines may be given to treat an infection caused by bacteria or parasites. Do not give your child over-the-counter diarrhea medicine unless directed by his or her healthcare provider.
• Do not give aspirin to children younger than 18 years. Your child could develop Reye syndrome if he or she has the flu or a fever and takes aspirin. Reye syndrome can cause life-threatening brain and liver damage. Check your child's medicine labels for aspirin or salicylates.
• Give your child's medicine as directed. Contact your child's healthcare provider if you think the medicine is not working as expected. Tell the provider if your child is allergic to any medicine. Keep a current list of the medicines, vitamins, and herbs your child takes. Include the amounts, and when, how, and why they are taken. Bring the list or the medicines in their containers to follow-up visits. Carry your child's medicine list with you in case of an emergency.

Manage your child's diarrhea:

• Give your child plenty of liquids. This will help prevent dehydration. Ask how much liquid your child should drink each day and which liquids are best for him or her. Give your baby extra breast milk or formula to prevent dehydration. If you feed your baby formula, give him or her lactose free formula while he or she is sick.
• Give your child oral rehydration solution as directed. Oral rehydration solution (ORS) has the right amounts of water, salts, and sugar that your child needs to replace lost body fluids. Ask what kind of ORS your child needs and how much he or she should drink. You can buy an ORS at most grocery stores and pharmacies.
• Continue to feed your child regular foods. Your child can continue to eat the foods he or she normally eats. You may need to feed your child smaller amounts of food than normal. You may also need to give your child foods that he or she can tolerate. These may include rice, potatoes, and bread. It also includes fruits (bananas, melon), and well-cooked vegetables. Avoid giving your child foods that are high in fiber, fat, and sugar.

Prevent acute diarrhea:

• Remind your child to wash his or her hands well and often. He or she should use soap and water. Your child should wash his or her hands after using the toilet and before he or she eats. You should wash your hands before you prepare your child's food and after you change a diaper.
• Keep bathroom surfaces clean. This helps prevent the spread of germs that cause acute diarrhea.
• Cook meat as directed before you feed it to your child.
  • Cook ground meat to 160°F.
  • Cook ground poultry, whole poultry, or cuts of poultry to at least 165°F. Remove the meat from heat. Let it stand for 3 minutes before you feed it to your child.
  • Cook whole cuts of meat other than poultry to at least 145°F. Remove the meat from heat. Let it stand for 3 minutes before you feed it to your child.
• Place raw or cooked meat in the refrigerator as soon as possible. Bacteria can grow in meat that is left at room temperature too long.
• Peel and wash fruits and vegetables before you feed them to your child. This will help remove any germs that might be on the food.
• Wash dishes that have touched raw meat in hot water with soap. This includes cutting boards, utensils, dishes, and serving containers.
• Ask your child's healthcare provider about the rotavirus vaccine. This vaccine helps to prevent diarrhea caused by the rotavirus.
• Give your child filtered or treated water when you travel. If you and your child travel to countries outside of the US and Europe, make sure the drinking water is safe. If you do not know if the water is safe, you and your child should drink bottled water only. Do not put ice in your child's drinks.
• Do not give your child raw or undercooked oysters, clams, or mussels. These foods may be contaminated and cause infection.
