A discussion of malaria pills is included here since you should decide on and start an antimalarial drug regimen before you arrive in an area where there is malaria.
Malaria is transmitted by the bite of an infected mosquito.
Malaria parasites invade a person's red blood cells, causing a disease characterized by headache, fever, chills, and sweating. These symptoms subside and then recur over periods of days. Left untreated, the disease may progress to anemia, heart or kidney failure, coma, and even death. Malaria is best prevented by avoiding mosquito bites. In addition to taking precautions against mosquito bites, you will want to take antimalarial pills if you are going to be in an area where there is malaria.
