Geographically, where has Malaria been known to occur?
The boundaries of malaria transmission are determined by the presence and abundance of anophelines, their susceptibility to malaria infection, the type of hosts they select for blood meals, and whether they live long enough to serve as effective transmitters of infection, which in turn is largely determined by ambient temperature and humidity. Although currently largely confined to what today would be considered tropical conditions, in the past, malaria (P.malariae and P.vivax) was epidemic as far north as Finland.
