Immunization Tips Many vaccines require multiple doses and time to take effect -- PLAN AHEAD!! Aim to be “globally available” Who Pays? - Depends on hiring scheme. i.e. PSC, Direct Hire, Military Where to get? - State Department Clinic, Travel Clinics, Private Plans. Other types of prevention should always be practiced to prevent transmission of infectious diseases.
Don’t Forget Prescription Medications –Adequate supply Divided supply among two pieces of luggage. **Keep in original, labeled prescription bottles** Carry a copy of practitioner’s medical prescription. Spare Eyeglasses/Contact lenses Copies of important documents (e.g., Passport, Health Insurance Papers, Yellow Card) MedEvac insurance

Use Common Sense This is not “home” Laws and Customs/Culture are different Medical Services available are different Many items may not be available or the quality may be questionable. That dog or cat is probably not someone’s pet or vaccinated Take Nothing For Granted!
Health Services While Abroad Different standards may exist. –Blood supply, sterility of instruments Payment is often required up front. Consult the embassy for recommended facilities if needed. Unreliable availability and quality of pharmaceuticals. Medevac insurance is wise.
Taking Care of Yourself: “ Accidents & injuries kill more travelers than exotic infectious diseases.” Wear a seatbelt Drink in moderation Jog/walk in safe places Be aware of your surroundings and those around you Know your quarters - door locks, smoke detectors, balconies, emergency exits
STRESS Take time to unwind –Run –Walk –Read –Radio –Play
Coping With Stress Listen to your body –How do you exhibit being stressed? –How do you cope with stress? Minimize Jet Lag Talk with colleagues Do you need someone else to talk to Critical Incidence Stress Debriefing (CISD) Stress will have an effect at both the individual and team level
Food Choose fruits & vegetables that can be peeled. Avoid unpasteurized dairy products Avoid raw or uncooked foods except for fruits & vegetables
Food Avoid food from street vendors Piping hot food is safer Baked goods are safer Avoid using ice Avoid using table condiments Ask for restaurant recommendations

Coffee, tea, beer, wine and soda are suitable choices - best to drink from original container
Water Treatment Boiling - most reliable, not always convenient. –Vigorous, rolling boil for 1 minute - let cool to room temperature –If at altitude (>6,562 ft [2km]) boil for 3 minutes or use chemical disinfection Portable Filter or Purification Unit –May not filter out viruses. Chemical Disinfection with iodine tablets –Follow manufacturer’s instructions carefully
Diarrheal Diseases Most common health problem among travelers to developing countries. Different causes: –Viral (rotavirus) –Bacterial (cholera, shigellosis, E. coli) –Protozoal (giardiasis) –Stress –Other Treat according to type.

Vectors of Disease Mosquitoes Ticks Flies Snails Fleas, lice and mites
Mosquitoes Different species transmit different diseases malaria yellow fever dengue filariasis Japanese encephalitis Night biters vs. day biters Breeding areas vary by species. Urban vs. rural
Malaria 4 protozoan species: –P. falciparum –P. vivax –P. ovale –P. malariae Transmitted by Anopheles mosquitoes. –Bite between sunset and sunrise. –Breed in sunlit streams, shaded lagoons, rice fields & marshes. Disease is characterized by: –Fever, chills, sweats –Flu-like symptoms –P. falciparum may progress to disorientation, delirium, coma, etc.
Malaria Priority: Prevention Is malaria present? See www.cdc.gov site.www.cdc.gov Are drug-resistant strains present? Prophylaxis - both personal & environmental –Prescription medication –Long pants/Long-sleeved shirts –Insect Repellant –Netting treated with insecticide (i.e. Permethrin) –Awareness of possible breeding grounds –Limit night-time outdoor activity

Mefloquine –250 mg/week starting 2 weeks before, for duration of stay & for 4 weeks after. –Avoid if history of seizures, psychiatric disorders or cardiac condition. Doxycycline –100 mg/day starting 1-2 days before, daily while there & daily for 4 weeks after.
Vector Protection Long pants/Long-sleeved shirts DEET (30% - 40%) or other insect repellant Permethrin treated bed netting Permethrin treated outer clothing, especially pants legs & waist, shirt sleeves & collars Hard-soled, closed-toe shoes Avoid areas of long grass, heavy brush Avoid wading in rivers, lakes, or streams –if unavoidable, immediate and vigorous towel drying may help

Heat Exhaustion and Stroke Exhaustion –dizzy, fatigue –headache –pale & clammy –fast, shallow breathing –muscle cramps –intense thirst –Rehydrate Stroke –Medical Emergency –hot, dry, flushed skin –no sweating –high body temperature –rapid heartbeat –confusion –loss of consciousness –Cool
Exposure to Cold Wear Multiple Layers - loose fitting Proper fitting footwear Hat and mittens - 40% of heat lost through head Hydrate
Frostbite Treatment: –Warm environment ASAP –Unless necessary, do not walk on frostbitten feet –Immerse in warm (not hot) water –Warm using body heat –Do not rub frostbitten area –Do not use heating pad, heat lamp or stove to warm –Medical attention

Landmines and Ordnance Estimated 110 million mines currently in 64 countries –Heavily Mined: Cambodia Egypt Angola Bosnia-Herzegovina Many areas with unexploded ordnance Be aware of where you are walking or driving
Importance of Maintaining Health Of little use to DART, and its mission, if unable to fulfill role Decreased stress on family and others Easier, and cheaper to prevent than treat
