Why not prepare your travel health details as carefully as your itinerary? A happy, healthy and safe excursion could depend on using Dr. Isadore Rosenfeld of the Fox News Channel's 8 Travel Tips for an overseas vacation.

1. Have current immunizations.

Check with the CDC on the internet at www.cdc.gov/travel and specify which countries you will be traveling, to check on the current immunizations required. This site also has many suggestions on staying healthy during your trip.

2. Brush your teeth with bottled water.

Local water sometimes carries parasites and bacteria that can make a non-local ill. For that reason, don't brush with tap water use bottled water instead. In lieu of bottled water, boiling local tap water for a at least 1 minute will kill any diseases that could cause illness.

3. Peel fruits and vegetables, don't eat them raw with the skin.

Local fruits and vegetables can also harbor parasites and bacteria that can make a healthy traveler ill. For that reason, the CDC advises not buying food from street vendors. Dr. Rosenfeld proposes skinning raw fruits and vegetables before eating. Always be sure that your food is cooked fully.

4. Take additional medication with you.

Running out of necessary medicine could ruin a great vacation. The unexpected does happen, so why not prepare for it now? Plan on packing several days more prescription medication than the number of days you plan on traveling. Then you can rest easy during a delay, knowing your health is secure.

5. Take a first aid kit.

Build a first aid kit to pack in your suitcase. A smaller kit that you can keep with you is a good idea as well. In your suitcase kit, include anti-diarrheal medication, mild laxative and anti-motion pills as your destination dictates. You should also include antihistamine and decongestant, anti-fungal and hydro cortisone cream in 1% solution. The kit that stays with you through your day should include anti-inflammatory medications, antibiotic cream and the typical assortment of alcohol pads, latex gloves, band aids and moleskin for blisters.

6. Make a travel insurance investment.

Because no one has a crystal ball, it's a good idea to purchase travel insurance so an anticipated trip isn't a disappointment financially as well as emotionally when something goes wrong.

7. Avoid swimming in ponds or lakes.

Parasitic and bacterial diseases can exist in lakes and ponds as they can in local drinking water. Avoid swimming in still bodies of water. Swimming in the ocean or in chlorinated swimming pools is okay. But swimming in a local river should be avoided.

8. Prepare for mosquitoes.

Bring insect repellent including DEET of 20-50% for adults and children over 2 months. Wear long sleeved shirts and pants and spray them as well. Wear sunscreen first then apply the repellent and wash off again before going to bed. These precautions will help fight off mosquitoes, ticks and fleas. Mosquitoes transmitting malaria are most active at dusk and dawn while daytime mosquitoes tend to transmit dengue fever.

Should a serious illness or injury occur to you or a traveling partner, there are several places you can seek help. One such organization is MEDEX, www.medexassist.com. The American Society of Tropical Medicine and Hygiene and The International Society of Travel Medicine are two more organizations that offer different areas of help. Check their websites for more information before leaving.

Healthy travel is easy if you are prepared. Enjoy your travels knowing you are prepared for the worst which, universally speaking, means the worst probably won't happen.
