Disease-specific guidance for this destination

Measles

Before traveling internationally, make sure everyone in your group is protected against measles — ideally at least 2 weeks before departure.

If you get sick while traveling

Emergency — trouble breathing, chest pain, confusion, severe bleeding, seizures:

Call 911

For non-emergency illness, contact your hotel, travel insurer or the nearest embassy for a list of local doctors and hospitals.
Tell the clinician where you have traveled and any animal, mosquito or sick-person contact.
Check that your health insurance covers care abroad; consider travel health and medical-evacuation insurance.

CDC: Getting health care during travel

After you return

If you develop a fever, rash, or other symptoms in the weeks after your trip, see a healthcare provider and tell them where you traveled.
Some infections (for example measles or malaria) can appear weeks after return; call ahead before visiting a clinic if you have a fever and rash.
