Answer

The mechanisms that underlie immunity remain poorly defined. Additionally, individuals who develop immunity to malaria who then leave the endemic area may lose protection. Travelers who return to an endemic area should be warned that waning of immunity may increase their risk of developing several malaria if reinfected. These travelers returning to endemic areas are a special population, sometimes termed visiting friends and relatives (VFRs).
