Costa Rica, with its stable democracy and thriving tourist industry, is generally considered a safe country to visit. However, travelers should be aware that they may become targets for petty theft and scams â€“ easily avoided if precautions are taken. It is a good idea to keep valuables in a bra or inside pocket when in crowded places like buses and markets. Refrain from visiting the ATM after dark, and don't walk alone at night.
The most common health issue that affects tourists in Costa Rica is traveler's diarrhea, so it is a good idea to bring along an antidiarrheal drug, such as Cipro. Diarrhea can generally be prevented by avoiding suspicious foods, such as fruit without a peel and anything that has been sitting out. Costa Rica isn't affected by malaria except for the Limon Province, so if you plan to head there you should probably pick up some malaria pills. Other than that, check with your doctor about what shots you need before embarking on your trip.
