RESUMO
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. 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.
RESUMO
Introduction: Five out of eight districts of Saurashtra region are declared hyper endemic for malaria in the year 2011-12 & 2012-13 and given priority by World Bank Project for Malaria control activity in these districts. Burden of malaria contributed by these districts is more than 40% of total burden of Gujarat state, and Jamnagar is one of those districts. By Studying trend of Malaria in Jamnagar district will give an opportunity to identify particular seasonal trends and thus by effective surveillance mechanism, future out-breaks can be prevented. Aim & Objectives: 1) To study the trend of malaria situation in various Talukas of Jamnagar District. 2) To compare the trends for last four years. Materials & Method: Present record base study was carried out in 10 Talukas of Jamnagar district to analyzed the trend of malaria situation in the Jamnagar district by department of community medicine, Shri M.P.Shah Medical College, Jamnagar during the month of September 2012 to analyze the trend from the year 2009 to 2012 (up to September month). This was based on the monthly and progressive data format (monthly reports) was collected form District Malaria Officer of Jamnagar district and analyzed by using Microsoft excel 2007 and the result was presented in Table and graph. Results: Total numbers of cases were decreasing over the period of last 3 years. ABER is >10% in most of the Talukas which is indicated the surveillance activity is done properly over the period of years. Conclusion: In the year 2012 all parasitological indicators showing decreasing trend of malaria in comparison with previous years i.e. API, ABER, SPR, PF, and no malarial deaths at all. Continuous surveillance is effective in reduce the morbidity and mortality of vector borne disease like malaria. Seasonal trend of malaria follows the same pattern of distribution showing peak in months of Jun-July.
