Abstract
Aim: Malaria remains an enormous public health problem. Regular and ongoing surveillance to detect changes in its trends to initiate the control measures is the need of the hour. The present study was undertaken to provide the malaria transmission dynamics using surveillance indicators through active and passive surveillance in district Faridkot. Usefulness of rapid malaria diagnostic test was also evaluated. Methodology: This retrospective study extended over a period of two years (2010-2011). Thick and thin blood smears were prepared from suspected cases of malaria complaining of fever and headache for the last three days (i) of 2 CHC’s, 8 PHC’s and 68 sub centers as a part of active surveillance and (ii) those who visited GGS Medical College & Hospital and civil hospital Faridkot as a part of passive surveillance. Out of all the samples collected during the passive surveillance 995 samples collected at GGS Medical College and Hospital, Faridkot were also subjected to rapid diagnostic test (OptiMAL). Results: The annual blood examination rate (ABER) was 9.0 and 9.7 in 2010 and 2011 respectively. Annual parasite incidence (API) recorded was < 2 (0.5) in both the years and slide positive rate (SPR) was 0.5 and 0.05 in the two respective years of study. Significant gap in the rate of case detection of active and passive surveillance systems was observed with predominance of passive surveillance. More than 96% of cases were of P. vivax. Research Article British Microbiology Research Journal, 3(3): 339-345, 2013 340 RDT’s showed an excellent correlation with conventional microscopy. Conclusion: Malaria (P. vivax) is a persistent problem in the Malwa region with variation in its transmission dynamics with in the year. P. vivax is the main species of malarial parasite in the Faridkot district with occasional cases of falciparum malaria. Prevention strategy should be targeted towards on the spot diagnosis by using RDT and hence prompt treatment. It could help to prevent spread of drug resistance and complicated malaria.
