Introduction, transmission and aggravation of malaria in desert ecosystem of Rajasthan, India.

Abstract

Importation of malaria cases was the major cause of seasonal introduction of malaria in the desert. This initial or primary parasitic load available in a village leads to a particular transmission quantum depending upon the density of vectors, human and cattle population at a particular time. Areas with more imported cases when coupled with profuse vector population lead to epidemic malaria situations in the desert.
