Abstract

Malaria is under regular and ongoing surveillance, to detect changes in its trends or distribution in order to initiate investigative or control measures in the country. Owing to limited availability of resources and rational use under the program, prevention and control activities against malaria varies in areas with different intensity of malaria transmission. Transmission dynamics, surveillance, mapping of disease burden for malaria in arid ecological setting of Jodhpur, Rajasthan has described in this study. Monthly epidemiological reports of Jodhpur City, district Jodhpur and all its community health centres were obtained from the office, Chief Medical and Health Officer district Jodhpur for the period 2002 to 2006. Secular trend of malaria incidence, transmission dynamics, mapping of disease burden areas and surveillance of malaria was described. The range of annual parasite incidence (API) was from 0.52 to 2.85 in district Jodhpur, with API <2 in the last consecutive 3 years (2004 to 2006). The slide positivity rate (SPR) ranged from 0.59 to 2.29 in district Jodhpur with continuous decline from 1.51 in 2004 to 0.56 in 2006. Transmission dynamics of total malaria varies from one year to another. Total malaria cases during each year reached at peak in the different months in the duration of 2002 to 2006. Malaria is a persistent health problem in district Jodhpur with variation in its transmission dynamics within and between the years. District Jodhpur with its rural and urban areas is a low risk area for malaria. Malaria prophylaxis and management strategies as applicable in low risk area would be appropriate for district Jodhpur.
