title: Epidemiological situation of malaria in South East Asia with focus on India.
abstract: Malaria contributes a most stimulating chapter in the annals of biological parasitism. At present the disease is endemic in 91 countries with about 40% of world population at risk. Among all infections malaria continues to be one of the biggest contributors to disease burden in terms of morbidity, suffering and deaths specially in Africa. By lowering the productivity it is closely linked to poverty and contributes significantly to stunting social and economic development.We, in South East Asia, are living in paradoxical situation, on one side we spent large sums and energy to control/eradicate malaria and on the other hand we simultaneously create malariogenic conditions in the process of development efforts eg. irrigation canals, water supply scheme and urbanisation.The disease is endemic in all the seven countries of South East Asia with P.f.% ranging from 2.47% in Nepaa to 55% in Pakistan. In India although the total number of cases are almost static in last 10 years however the P.f. cases are on increasing trend.The malaria in tribal area is further posing a great threat. Annually 0.2% of the population suffers with malaria. However it is 1.5% in tribal area and 60% of deaths due to malaria are reported from tribal area. In 1984 there were 24% cases ofP. falciparum malaria out of them 57% were in tribal area however in 1995 the total cases increased to 36% and P.f. proportion to 75%. Technical side the chloroquine resistance and insecticidal resistance are also spreading in new area which also complicate the disease epidemiology.The migration of population, deforestation, inadequate resources increase in epidemic potential and neglect of epidemiology are other important factors responsible for changing epidemiological pattern of malaria.
