Becoming and Staying a Healthy International Traveler

It's important to do certain pre-trip tasks before you travel overseas. Part of that pre-trip preparation, is knowing that the first thing you should pack is" common sense" when it comes to maintaining your health. Traveling internationally isn't a vacation from your doctor's orders, taking your prescribed medications, or following your doctor's instructions on diet and exercise. Some of these pre-trip tasks need to be started almost from the moment you are planning your trip. Here is my top list for becoming and remaining a healthy international traveler.

I. The Importance of Getting a Physical Before International Travel

I can't stress enough how important it is to get a physical exam before any international travel. You should always get a medical clearance from your primary physician before traveling to international destinations. This is especially true, if you have any pre-existing conditions or if you are an older traveler or if you are traveling with children. Additional precautions should be taken if you are traveling to third world countries, rural areas, for extended stays, or adventure type vacations.

II. Update Your Immunizations and Check Out the Health Advisories for Your Destination

Even if you are just taking a cruise to Cancun, Puerto Rico, or elsewhere -- you need to make sure that your immunizations are updated. You also need to be absolutely aware of the health advisories for your international destination. Always be certain to be aware of the specific health precautions for your international destination, it could save your life. I've provided links below, for ease of information to the Center for Disease Control and the U.S. Department of State's travel advisories.

III. Find Out If You Need a Vaccine or Booster Immunization

Immunizations obviously depend upon your destination. Additional considerations are:

  • How long you plan to stay
  • Your medical condition

If your trip is only a couple of months away, you should see your primary physician at least four to six weeks prior to your trip. However, truth be told, you probably should schedule this discussion about what immunizations you need at least four to six months to that trip. Why? Some immunizations require several injections spaced days, weeks or even months apart. In addition, you should make sure that you've had your primary vaccine series, such as:

  • Diphtheria
  • Measles
  • Mumps
  • Pertussis (aka Whooping Cough)
  • Polio
  • Rubella
  • Tetanus

Important Things to Ask Your Doctor:

  • Be sure to ask if you need a tetanus and diphtheria booster. (Since it's recommended that with tetanus and diphtheria that a booster does of adult tetanus-diphtheria is given every ten years).
  • Be sure to ask if you need a polio booster. (If you haven't had a polio booster as an adult, you may need this. This is especially true if you are traveling to Africa, Asia, the Middle East, India, and neighboring countries).
  • Be sure to ask if you need a measles vaccine booster. (This is important if you were born in 1957 or after).
  • Be sure to ask if you need an additional yellow fever vaccine. (This is important if you are traveling to Africa or South America).
  • Be sure to ask if you need any of the hepatitis vaccines. (Hepatitis A vaccine or immune globulin, is recommended anyone traveling outside of Japan, Australia, New Zealand, Northern and Western Europe, Canada, and the U.S). (Hepatitis B vaccine, is recommended if you are traveling to Southeast Asia, Africa, the Middle East, islands off the South and Western Pacific, and parts of Central and South America. It is also recommended if you will be on an extended stay or rural areas).
  • Be sure to ask if you need vaccination against typhoid. (Recommended if you are traveling to a third world country).
  • Be sure to ask if you need a meningococcal vaccine. (Recommended for travel to sub-Saharan Africa).
  • Be sure to ask if you need a vaccination against Japanese encephalitis. (Recommended if you've be staying long-term in Southeast Asia where this is a common disease).
  • Be sure to ask if you need a vaccination against rabies. (This is only recommended for long stays in third world countries).

Remember: Many international regulations command proof of yellow fever vaccinations and other vaccinations for travelers into certain countries. Make sure you carry your International Certificate of Vaccination as you travel outside of the U.S.

IV. Don't Forget to Visit Your Dentist

Nothing can put a big damper on a long planned international vacation or business trip, than finding yourself with a horrible toothache or dental abscess. Imagine being at the beginning of a non-stop twelve hour flight to 7 sultans Hong Kong in a pressurized airplane, and developing a horrible toothache when you accidentally bit down on something and broke a tooth? Alternatively, imagine being in a third world country when you suddenly develop a dental abscess on a tooth, that was just slightly sore before you left? Neither of these or similar situations, are ones that should be a part of international travel. Have your cavities filled, poorly fitting dentures adjusted, and other dental work done before you go.

V. Plan Ahead With Medications

Suddenly finding out that your international stay has been extended and running out of a needed prescription, could be a giant headache when you travel abroad. Prevent this from happening to you by packing more of your medications than you need and get prescriptions filled before you go. Make sure, that your medications are in their original pharmacy bottles, clearly labeled and that they match your name. Having unidentified pills or pills in your companions name in your possession, can cause problems with airport security in the U.S.

Prescription services being what they are today in the U.S. -- Some companies having stringent rules about only filling the prescription every 21 days, etc. can cause additional problems. Be aware that there are exceptions to this rule and that your physician can intervene, should the prescription insurance overseers become unbending about their rules and regulations. Also, remember that if you are taking a prescription narcotic, it is important to obtain a letter of authorization from your doctor on his letterhead.

Travel Health for Disease Prevention
VI. Travelers Diarrhea the Most Common Travel Health Issue

One of your biggest concerns in any international destination is the absolute possibility of having some sort of stomach upset. Fifty percent of all travellers develop traveler's diarrhea. Here are some ways to reduce your risk:

  • Only eat foods that are well cooked and served hot;
  • Only drink bottled water, sodas, beer or wine served in their original containers;
  • Coffee and tea that has been boiled is also a safe choice;
  • Avoid salad bars;
  • Avoid buffets;
  • Avoid raw or uncooked fruits and vegetables that you haven't cleaned yourself with bottled water;
  • Avoid raw or undercooked meats;
  • Avoid dairy foods;
  • Never drink tap water or use ice cubes;

Finally, make sure you carry, not only anti-diarrhea over-the-counter medications, but obtain a prescription from your primary physician for an antibiotic. Many physicians will prescribe a limited amount of such medication as a precaution once they understand why you might need it.

VII. Other Common International Traveler Ailments

Other concerns in maintaining international traveler health are the following ailments:

Motion Sickness - The bad news is that motion sickness can strike anyone, anywhere on any type of transportation and of course, it's not fun. However, the good news is that motion sickness can be prevented by:

  • Taking over-the-counter Dramamine, Marezine, or Bonine -- thirty to sixty minutes before getting on-board;
  • Getting plenty of fresh air. This means on-board a plane, direct the air vent at your face. This means on a train take a seat near a window and face forward. This means in a car, drive or sit in the front passenger seat.
  • If you already know you have problems with motion sickness, talk to your doctor.

Heat Exhaustion - In the summer and in hot climates heat exhaustion is always a very real possibility for travelers. To prevent this:

  • Pace yourself;
  • Plan regular breaks in the shade or inside an air-conditioned building;
  • Carry water;
  • Don't overeat;
  • Drink liquids frequently;
  • Avoid alcohol;
  • Wear lightweight clothing;
  • Wear light colored clothing;
  • Wear a hat;
  • If you are feeling weak, dizzy, nauseated -- get out of the sun immediately.

Blisters - International travel is not time to break in a new pair of shoes! However, even your most comfortable shoes can sometimes be a reminder to:

  • Pack more than one pair of comfortable shoes;
  • Wear socks dusted with talcum powder or foot powder;
  • Use foot inserts.

Altitude Sickness - Higher altitudes can cause altitude sickness even in healthy adults and children. Symptoms of altitude sickness are: Headaches, shortness of breath, fatigue, nausea, and difficulty sleeping. Prevention of altitude sickness includes:

  • Pace yourself, going slowly, especially after altitudes of 9,000 feet;
  • Rest for 24 hours after arriving;
  • If out of breath or tired, slow down!;
  • Don't climb more than 3,000 feet in any one day below 12,000 feet;
  • After 12,000 feet, don't climb more than 1,000 feet per day;
  • When climbing, always sleep at the lower altitude;
  • Don't use alcohol;
  • Don't smoke;
  • Get a prescription for actazolamide (Diamox) or other such medication prior to the trip from your doctor. This may prevent or lessen symptoms.

VIII. Pack Your Medical History Summary

One item not to forget, just in case you should have a medical emergency, is a copy of your medical history. This is especially true, if you have a history of heart problems or have a pacemaker. Also, obtain and pack a copy of a recent ECG.

IX. Air Travel Hazards

While air travel is one of the fastest and safest ways to travel, it also puts you at certain health risks while traveling. Here are some suggestions for preventing them:

Blood clots and leg swelling- Sitting for long periods of time in a cramped airplane will cause fluid to accumulate in the soft tissues of your legs. This can cause a life-threatening complication of a blood clot (thrombophlebitis). To prevent this:

  • Stand up and stretch periodically;
  • Take a walk up and down the isle every hour or so;
  • Flex your ankles;
  • Press your feet against the floor or seat in front of you;
  • Wear support hose if you are already prone to swelling;
  • Wiggle and move your toes and feet periodically;

Dehydration - To prevent dehydration on the plane, drink plenty of liquids (water and fruit juices). Also, avoid alcohol and caffeine during flight.
Ear Pain - Some people have trouble with ear pain during ascent or decent. To avoid this:

  • Take a deep breath and hold for a few seconds;
  • Slowly exhale part of the air while pursing your lips;
  • With lips closed tight, gently blow remaining air out;
  • Then breathe normally;
  • Some people find that yawning, chewing gum; and swallowing also helps;
  • Jet Lag - We all know about this travel hazard and it's difficult to avoid if you are crossing several time zones. The best possible thing to do is drink plenty of fluids, eat lightly, and remember to pace yourself once at your destination to accommodate jet lag.

X. International Traveler's First-Aid Kit

Packing a travel first aid kit can help you treat yourself and any fellow travelers for minor medical emergencies. Here is a list of basic supplies:

  • Antacids
  • Antibacterial cream
  • Antidiarrheal medication
  • Adhesive tape
  • Antihistamine
  • Benadryl
  • Bandages
  • Calamine
  • Decongestant
  • Deet (if traveling to mosquito infested location)
  • Laxative
  • Over-the-Counter heartburn or acid reflux medicine
  • Over-the-Counter motion sickness medications
  • Anti-itch cream
  • Second pair of prescription glasses if you have them, if not your eyeglasses prescription
  • Sunscreen
  • Thermometer
  • Tweezers

XI. Safe Food and Water While Visiting Abroad

One of the most healthy travel tips to remind everyone of, is to take proper food and water precautions once you arrive at your destination. Just use your common sense. If you follow the guidelines listed above in VI. Travelers Diarrhea -- You shouldn't encounter any problems with safe food and water.

  • Yellow Fever
  • Hepatitis
  • Hemorrhagic Fever
  • Japanese Encephalitis

Without doing into great detail, none of these illnesses are ones that anyone would want to contract and some of them are life threatening. The only real way that you can prevent them is to eliminate your exposure to this insect. This means:

  • Use of insect repellents such as DEET
  • Wearing protective clothing;
  • Wearing insecticide (permethrin) clothing;
  • Use of mosquito netting

XIV. Health Issues When Traveling With Children

Traveling abroad with children and insuring that they are healthy before, during, and after the trip is very important. Today, many children are traveling with their parents overseas. The main thing is to try to make your trip as safe and hassle free as possible. Some suggestions are:

Additionally, anyone travelling overseas should consider purchasing international travel health insurance. Keep in mind:
