Which doctor treats this

• Start with your primary care provider (family doctor or internist).
• They may send you to an infectious disease specialist, if it's hard to treat.

Back to school, work, or sports

• Stay home until 2 days after vomiting and diarrhea stop, especially if you work with food, children, or patients.
• Wash hands well after using the toilet.

Pregnancy and breastfeeding

• If you're pregnant or planning to be, tell your prenatal provider about this condition.
• Some infections can pass to the baby during pregnancy or birth. Tell your provider if you've been exposed.
• Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
• Ask before taking any pain reliever. The FDA advises avoiding ibuprofen and naproxen after 20 weeks unless your doctor says to.
• Breastfeeding: Most medicines are fine, but ask. The NIH LactMed database lists what's known about each one.

Outlook

Outlook depends on the cause; early care helps.
