Malaria produces recurrent attacks of chills and fever. Caused by a parasite that's transmitted by mosquitoes, malaria kills about 1 million people each year worldwide.
While the disease is uncommon in temperate climates, malaria is still prevalent in tropical and subtropical countries. World health officials are trying to reduce the incidence of malaria by distributing bed nets to help protect people from mosquito bites as they sleep. A vaccine to prevent malaria is currently under development.
If you're traveling to locations where malaria is common, take preventive medicine before, during and after your trip. Many malaria parasites are now immune to the most common drugs used to treat the disease.
