Tackle everything from jet lag to malaria (and those pesky mosquitoes) with our guide to staying healthy abroad.
Always bring your own medical supplies–including syringes, antibiotics, even condoms–when traveling in developing countries. The ones sold in foreign drugstores could be expired, fake, or unreliable.
For travel to developing countries
Unlike back home, waterborne viruses are a concern in nations such as Nepal or Tanzania. UV purifiers (such as the SteriPen Adventurer; $100, steripen.com) are small and kill viruses, bacteria, and protozoa in seconds–but are pricey and require batteries. Chemical treatments like chlorine dioxide or iodine are cheap, light, and kill all pathogens–except for cryptosporidium, which iodine can't squash (and it'll take 4 hours for chlorine dioxide to neutralize crypto). The First Need XL Water Purifier ($103; generalecology.com) and the MSR Sweetwater system ($80, msrgear.com) are fast and effective against viruses and other nasties. Boiling also gets the job done, but it'll cost you fuel and time for the water to cool. For travel to developed countries In places like Western Europe, Chile, Canada, and New Zealand, you can get by with a filter that removes only bacteria and protozoa. We like the light, packable MSR Hyperflow ($100; msrgear.com).
International travel requires a few additions to your standard medical kit. Keep these extra items handy, and store them all in their original bottles to simplify the trip through customs.
Climbing above 8,000 feet? Be alert for these altitude-induced conditions.

High Altitude Pulmonary and Cerebral Edemas (HAPE & hace)

Treatment Descend immediately and get medical attention.
In Africa, Central America, and Asia, skeeters are vectors for malaria, yellow fever, dengue fever, and more. To avoid a range of debilitating symptoms–from severe headaches to vomiting– follow these tips.
No vaccine for this life-threatening disease exists, but a course of anti-malarial drugs (such as chloroquine or doxycycline) can prevent infection. Travelers take pills starting two weeks to two days before departure (depending on the drug) and continuing one to four weeks after returning home.
