Health

Travelers should be aware of high-altitude conditions in Brazil and Argentina. Travelers (especially those with heart or lung conditions) are encouraged to take precautions and consult with their personal health-care providers before undertaking high-altitude travel. The best way to prevent “altitude sickness,” which sometimes results in headaches and nausea, is to make sure that you are well hydrated throughout your stay.

Sightseeing might involve walking on some uneven terrain (see “Walking on Tour”), and travelers should be in reasonable shape. While no vaccinations are required, it’s always advisable to check with your doctor at least eight weeks prior to departure for recommendations.

In order for you to stay healthy throughout your South American tour, we recommend the following:

• Drink bottled water. Refrain from drinking tap water, including when brushing teeth.
• Avoid eating fresh fruits and vegetables unless they are cooked or washed in clean water and peeled.
• Bring a small first-aid kit, including antacids, anti-diarrhea medication and any prescription medications.
