Ecological study of malaria disease in south 24 Parganas district of West Bengal
Dr. Debabrata Mistry
Man, mosquito and malaria parasite co-existed in Ganga Delta of West Bengal from ancient times. As a matter of fact, before the introduction of National Malaria Control Programme, malaria dominated the morbidity scenario in South 24 Parganas district. The main objective of this study is to know the spatial distribution and epidemiology of malaria disease in the area under study. The district South 24 Parganas is situated at the southern tip of West Bengal. Both primary and secondary have been collected for this study. The humid tropical climate with a heavy rainfall during the monsoon months forms an ideal environment for proliferation of mosquitoes. The common parasites found in this district are Plasmodium vivax and to a lesser extent of Plasmodium falciparum. Anopheles mosquitoes are the carriers of these parasites in this district. Cultural factors like level of living, housing condition, sewerage system income, rearing of animals, clothing etc. play a very significant role to spread of such vector borne disease in this district. Most of the people are not aware about the breeding place of mosquitoes. In this district morbidity of malaria is higher than other vector-borne diseases. Among five Subdivisions of this district, number of cases, Death Rate and Case Fatality Rate are more in Canning Subdivision. After that the Government of India has undertaken measures to eradicate malaria through National Malaria Control Programme, Malaria Eradication Programme and National Vector-borne Disease Control Programme.
