Malaria prophylaxis

Malaria prophylaxis refers to measures used to prevent malaria infection in individuals at risk of exposure to Plasmodium parasites transmitted by Anopheles mosquitoes. These measures include mosquito bite avoidance strategies and the use of antimalarial medications taken before, during, and after exposure. Prophylactic medication is commonly recommended for travelers to endemic regions and for certain populations living in areas with ongoing malaria transmission. The choice of prophylactic strategy depends on factors such as geographic location, parasite resistance patterns, patient characteristics, and duration of exposure.

Several malaria vaccines are under development.

For pregnant women who are living in malaria endemic areas, routine malaria chemoprevention is recommended. It improves anemia and parasite level in the blood for the pregnant women and the birthweight in their infants.

Most adults from endemic areas have a degree of long-term infection, which tends to recur, and also possess partial immunity (resistance); the resistance reduces with time, and such adults may become susceptible to severe malaria if they have spent a significant amount of time in non-endemic areas. They are strongly recommended to take full precautions if they return to an endemic area.
