SEASONAL VARIATION OF INTESTINAL PARASITOSIS IN KISHANGANJ DISTRICT, BIHAR
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 41
Abstract
BACKGROUND Seasonal variations in temperature, rainfall and resource availability are ubiquitous and can exert strong pressures on population dynamics. Several past studies, including a study on humans from the United States and a few others using animal subjects have revealed the burden of parasitic infections to rise during the monsoon months (July to October), showing the lowest load during winter. An attempt to assess the influence of seasonal variations on the prevalence of IPI, a retrospective study was done for a period of 36 months in our Tertiary Care Hospital in the eastern part of Bihar. MATERIALS AND METHODS The present study is a retrospective study undertaken in a rural medical college of Bihar, India. Patients of all ages who reported with gastrointestinal symptoms during the period of Jan. 2014 to Dec. 2016 were included in the study. A total number of 5638 patients of both sexes were found to fulfil the criteria of inclusion. Routine macroscopic examinations of stool were carried as per standard guidelines for presence of adult worms, scolices and proglottids. For microscopic examinations, saline wet mount and Lugol’s iodine wet mount were prepared as per standard protocol. RESULTS Our study was done retrospectively on 5638 stool specimens obtained from patients who were referred from outpatient departments (OPD). It was found that out of 5638 stool specimens examined, 1489 were sent during the monsoon itself out of which 698 (46.88%) specimens were positive for parasites. In other words, out of total 2672 parasite-positive specimens in a total span of three years, the monsoon brunt was 26.12%, compared to the winter counterpart which was 251, i.e. only 9.39%. After rainy season, the next parasitic cases were found in the order of: summer (601, i.e. 22.47%), autumn (417, i.e. 15.6%), dewy season (389, i.e. 14.56%), spring (316, i.e. 11.83%) and lastly winter as already mentioned (251, i.e. 9.39%). It has to be noted here that rainfall does not necessarily occur solely during rainy season, but also in other seasons, notably in summer and autumn. Our study tallies well with other similar studies. CONCLUSION Our studies reveal that the situation of intestinal parasitosis is maximum in summer and rainy seasons and minimum in dry, winter months. Periodic preventive anti-helminthic treatment should be instituted keeping in view with these findings.
