Immigrants are also distinguishable from other mobile populations by several characteristics that determine health and disease outcomes. One of these characteristics is directly related to the process of migration and the source and transition countries through which they have moved prior to arrival at their destination. For diseases like malaria that have a defined geophysical limit to the areas of endemic transmission and biological limitations on their incubation periods, the impact of this disease on incoming immigrants is both predictable and inevitable. There are four species of human malaria: Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, and Plasmodium malariae all of which are transmitted by the bite of a mosquito. Blood transfusion, shared equipment during intravenous drug use, and maternal-to-child transmission of malaria occur very rarely.
Of the 108 countries with endemic malaria, only 31 are considered “high impact” countries, most of which are in sub-Saharan...
