Several weeks before you travel, it is a good practice to visit a clinic specializing in travel health. Normally, the doctors of those clinics  are well trained to help you. In addition, the necessary vaccinations are available on site. Do not wait until the last minute. It is very unpleasant to fly with the side effects of some vaccines.

If you are already taking medication.
To avoid problems at customs with certain prescription drugs, it is wise to ask to your doctor for a medical certificate stating that you must take your medicines to treat a specific medical condition.
Make sure you bring enough medication you need for the duration of your trip. Your prescription may not be available in the country you visit.

Do you need a vaccine?
Vaccination is a good way to protect against certain diseases. Hepatitis is a disease that is very common even in industrialized countries. Ask your doctor what are the necessary vaccinations for your destination. Some countries require that travelers from abroad must be vaccinated for certain diseases. Bring your vaccination attestation as proof that you received the required immunization.

When a vaccine can not protect you.
For some diseases, there is no vaccine. Dengue fever and malaria are two examples. Many diseases are transmitted by insect bites like mosquitoes. Generally these mosquitoes are most active at dusk and during the night. Protect yourself with long clothes that cover the skin. Sleep in a room equipped with an air conditioner and whose windows are protected by mosquito nets. You can use an insect repellent containing DEET. Ask to your doctor if a preventive malaria treatment is necessary for the region you are planning to visit.

Water and raw foods.
Abroad, the water is often responsible for health problems. Always drink bottled water. In restaurants, ask for bottles who are  not uncorked. Food should be well cooked and hot in the mouth. Avoid eating bloody meat and salads of raw vegetables.

Do not leave without a small emergency kit.
Always carry a small emergency kit. This could include bandages, an antiseptic, some analgesic tablets, an antibiotic lotion to relieve sunburn, tablets against diarrhea and electrolyte sachets for hydration. If you go in the wilderness far from a hospital, ask your doctor to prescribe you  a broad-spectrum antibiotic in case of emergency.

Be well prepared to make a nice travel. (Page 6)
