Well, be careful if you go. There are more than 100 countries and territories where malaria still is a major risk. So take steps to protect yourself from the bite of the mosquito that carries the malaria parasite. The U.S. Centers for Disease Control and Prevention recommends taking an antimalarial drug before you travel and during your trip, using repellant with DEET, wearing long pants and shirts, and sleeping under netting dipped in permethrin if you're not living in screened or air-conditioned housing.
If you experience flu-like symptoms up to a year after returning from a high-risk area, see your doctor and get checked for malaria. Drugs can cure you.
