Ask the Doctor: Travel Safety

Q. What are some of the main health risks for those traveling abroad?
A. Some of the main risks are contracting diseases transmitted by insect bites, improperly prepared or contaminated food and drink, and sexual contact. Getting severe sunburn can also be an issue.

Q. How soon before my trip should I see a physician?
A. You should see your physician as soon as your travel plans are completed. It takes at least 30 days for some vaccines to be effective.


Q. Do I need immunizations if I'm staying in a first-class hotel or resort?
A. Yes. Your tetanus vaccination should be up-to-date (within 10 years) as well as hepatitis A, at the very least. You can get a current list of required and recommended vaccines on the CDC's Web site.

Q. How can I reduce my risk of getting sick?
A. Avoid insect bites by wearing long-sleeved shirts and pants if there are biting insects, especially in the evening, and use insect repellant (you should not apply it directly to your skin but on your clothing). Wash your hands before eating properly prepared foods. Remember that food goes bad sooner in warm climates. Be sure to drink clean water to stay well hydrated.

Q. Is it safe to drink the tap water during my trip?
A. This depends on where you are going. It is generally safe in more developed countries, but even then, you should be careful. Try to drink bottled water.
