When to see a doctor

The best time to see a doctor is before you travel to a developing country to ensure that you've received any available vaccinations and pre-travel advice for staying healthy.

If you develop signs and symptoms once you return home, talk to a doctor, preferably one trained in international medicine or infectious diseases. Tell your doctor where you've traveled.
