Malaria in stone quarry area of Faridabad complex (Haryana).

An analysis of five-year (1987-91) epidemiological data showed that the stone quarries contributed, on an average, 38.7% of malaria cases to the total of Faridabad Town and 11.6% to that of Faridabad district. Various malariometric indices like Annual Parasite Incidence (API), Annual Blood Examination Rate (ABER), Slide Positivity Rate (SPR) and Slide falciparum Rate (SfR) were analysed to assess the endemicity of disease, and attempts were made to compare them with the malaria parameters of the town and then of the district. Migrant population working as labour in stone quarries resides in areas conducive to malaria and hence the need for intensive control measures.
