How Long Are Stomach Bugs Contagious
The question of how long depends on the underlying organism, whether virus or bacteria, Dr. Delgado-Borrego says. As a rule of thumb, a child is contagious as long as theyre having diarrhea. Stomach bugs last a few days up to a couple of weeks.
The cessation of diarrhea is a common marker for when a stomach bug is no longer considered contagious. While vomiting wont last longer than 18 to 24 hours, diarrhea in infants and toddlers who have a stomach bug can sometimes last seven to 14 days, says Rashmi Jain, MD, pediatrician and founder of BabiesMD in California. During this entire time, they can still be shedding viral particles in their stools and be contagious. As pediatricians, we caution that children can be contagious until diarrhea has been resolved for a good 24 to 48 hours.
Children should be kept home from school or daycare and away from other people during this time.
What Stomach Infection Medicine For Kids Will Doctors Recommend
When the situation worsens, doctors will first examine the patient to determine the cause before prescribing a stomach infection medicine for a child or toddler. Do not self-administer antibacterial medications because they will not work on viruses. If it is a virus, there is no targeted treatment and the doctors will prescribe pain relievers to help the child stay comfortable through recovery. Also, avoid any type of anti-nausea or antidiarrheal medication as both vomiting and diarrhoea can help flush out the virus. For certain infections, antibiotics may be prescribed by doctors.
Treatment For The Stomach Flu
Most babies and kids wont need treatment for the stomach flu. Theres no specific treatment for the viruses that cause it.

Your doctor might recommend over-the-counter pain relievers to make your child more comfortable.

How To Treat A Stomach Virus
Despite its nasty nature, most kids recover from the stomach virus without any complications, and there isnt much you need to do while theyre ill. Generally speaking, dehydration is the biggest concern related to gastroenteritis. When a child is vomiting, you want to avoid dehydration,” says Dr. Kondis, “So encourage them to drink small amounts of an electrolyte-containing drink like Gatorade or Pedialyte.
On the other hand, it’s best to avoid food until your child is more likely to tolerate it. For the first 24 hours or so, it is best to keep the child from eating solid foods, because it will likely just cause them to vomit, says Dr. Kondis. Once you start to see the vomiting subside, and when your child tells you theyre feeling hungry, its best to start slow.
Introduce a dry food without strong flavors. Saltine crackers, white rice, or even a popsicle are a great place to start. Soon after, Dr. Kondis says its fine to allow children to eat whatever they feel like they can eat, including fruits, vegetables, yogurt, and carbohydrates.
How To Prevent A Stomach Bug

Remember to wash linens, bed sheets and other laundry on the longest washer setting possible using the warmest temperature. Dont shake the laundry before washing to limit the likelihood of the virus spreading to other areas of the house.
