CDC recommends the following vaccines (as appropriate for age)

See your doctor at least 46 weeks before your trip to allow time for shots to take effect.

• Hepatitis A or immune globulin (IG).
• Hepatitis B, if you might be exposed to blood (for example, health-care workers), have sexual contact with the local population, stay longer than 6 months, or be exposed through medical treatment.
• Japanese encephalitis, only if you plan to visit rural areas for 4 weeks or more, except under special circumstances, such as a known outbreak of Japanese encephalitis.
• Rabies, if you might be exposed to wild or domestic animals through your work or recreation.
• Typhoid, particularly if you are visiting developing countries in this region.
• As needed, booster doses for tetanus-diphtheria, measles, and a one-time dose of polio vaccine for adults. Hepatitis B vaccine is now recommended for all infants and for children ages 11–12 years who did not receive the series as infants.

• Wash hands often with soap and water.
• Because motor vehicle crashes are a leading cause of injury among travelers, walk and drive defensively. Avoid travel at night if possible and always use seat belts.
• Always use latex condoms to reduce the risk of HIV and other sexually transmitted diseases.
• Don’t eat or drink dairy products unless you know they have been pasteurized.
• Don’t share needles with anyone.
• Eat only thoroughly cooked food or fruits and vegetables you have peeled yourself. Remember: boil it, cook it, peel it, or forget it.
• Never eat undercooked ground beef and poultry, raw eggs, and unpasteurized dairy products. Raw shellfish is particularly dangerous to persons who have liver disease or compromised immune systems.

• Drink only bottled or boiled water, or carbonated (bubbly) drinks in cans or bottles. Avoid tap water, fountain drinks, and ice cubes. If this is not possible, make water safer by BOTH filtering through an "absolute 1-micron or less" filter AND adding iodine tablets to the filtered water. "Absolute 1-micron filters" are found in camping/outdoor supply stores.
• If you visit an area where there is risk for malaria, take your malaria prevention medication before, during, and after travel, as directed. (See your doctor for a prescription.)

• Pay special attention to mosquito protection between dusk and dawn. This is when the type of mosquito whose bite transmits malaria is active.
• Wear long-sleeved shirts, long pants, and hats.
• Use insect repellents that contain DEET (diethylmethyltoluamide).
• Read and follow the directions and precautions on the product label.
• Apply insect repellent to exposed skin.
• Do not put repellent on wounds or broken skin.
• Do not breathe in, swallow, or get into the eyes (DEET is toxic if swallowed). If using a spray product, apply DEET to your face by spraying your hands and rubbing the product carefully over the face, avoiding eyes and mouth.
• Unless you are staying in air-conditioned or well-screened housing, purchase a bed net impregnated with the insecticide permethrin or deltamethrin. Or, spray the bed net with one of these insecticides if you are unable to find a pretreated bed net.
• DEET may be used on adults, children, and infants older than 2 months of age. Protect infants by using a carrier draped with mosquito netting with an elastic edge for a tight fit.
• Children under 10 years old should not apply insect repellent themselves. Do not apply to young children’s hands or around eyes and mouth.
• For details on how to protect yourself from insects and how to use repellents, see Protection against Mosquitoes and Other Arthropods.
• If you are visiting friends and relatives in your home country in areas where malaria occurs, please read the malaria prevention recommendations for recent immigrants on the CDC malaria site.
• To prevent fungal and parasitic infections, keep feet clean and dry, and do not go barefoot.

• Don’t eat food purchased from street vendors.
• Don’t drink beverages with ice.
• Don’t handle animals (especially monkeys, dogs, and cats), to avoid bites and serious diseases (including rabies and plague). (For more information, please see Animal-Associated Hazards.)
• Don’t swim in fresh water (except for well-chlorinated swimming pools) in certain areas of China (southeast, east, and Yangtze River valley) to avoid infection with schistosomiasis. Salt water is usually safer. (For more information, please see Swimming and Recreational Water Precautions.)

• Long-sleeved shirt, long pants, and a hat to wear while outside whenever possible, to prevent illnesses carried by insects.
• Insect repellent containing DEET.
• Bed nets impregnated with permethrin. (Can be purchased in camping or military supply stores. Overseas, permethrin or another insecticide, deltamethrin, may be purchased to treat bed nets and clothes.)
• Flying-insect spray or mosquito coils to help clear rooms of mosquitoes. The product should contain a pyrethroid insecticide; these insecticides quickly kill flying insects, including mosquitoes.
• Over-the-counter antidiarrheal medicine to take if you have diarrhea.
• Iodine tablets and water filters to purify water if bottled water is not available. See Do’s above for more detailed information about water filters.
• Sunblock, sunglasses, hat.
• Prescription medications: make sure you have enough to last during your trip, as well as a copy of the prescription(s).

If you have visited a malaria-risk area in East Asia, continue taking your antimalarial drug for 4 weeks (chloroquine, doxycycline, or mefloquine) or 7 days (atovaquone/proguanil) after leaving the risk area.

Malaria is always a serious disease and may be a deadly illness. If you become ill with a fever or flu-like illness either while traveling in a malaria-risk area or after you return home (for up to 1 year), you should seek immediate medical attention and should tell the physician your travel history.
