Overview: epidemiology of malaria and its control in countries of the WHO South-East Asia region.

ABSTRACT

The malaria situation in the WHO South-East Asia Region is reviewed in terms of its epidemiological diversity, problems encountered and implications for control. Varying host-parasite-vector interrelationships are shown to be influenced significantly by prevailing environmental conditions (eg topographic, climatic) as well as behavioral and socio-economic determinants. Drug-resistant falciparum malaria and vector resistance to insecticides are the main biological deterrents to the success of control programs. Thus, the potential for malaria transmission remains high in many places. The malaria control strategy includes Primary Health Care and integration with basic health services. However, operational research is needed in many of the countries in the Region.
