Abstract

Background:  Vector-borne diseases pose a devastating obstacle to human health and overall economic development. It is responsible for 17% of all infectious diseases and more than 700000 deaths annually. Among vector borne diseases Dengue fever is the most rapidly spreading with an incidence, increased 30 fold in the past 50 years.  Awareness regarding dengue and its control measures through health education is one of an important component of integrated vector management. It can bring down larval indices and thereby reduce the mosquito density, and bring down the morbidity and mortality caused by mosquito borne diseases. Hence an intervention study was undertaken to study the impact of health education on larval indices and fever cases in a rural field practice area of Thrissur district Kerala. 


Methodology: A quasi randomized control study was conducted from, January2019- March 2020 in ward 13 of Thrikkur Panchayath, Thrissur district. Total 960 households were surveyed for indoor and outdoor water holding containers and inspected for the presence of mosquito larvae. The larval indices like House Index (HI), Container Index (CI) and Breteau Index(BI) were calculated as per the procedure of WHO. The total number of fever cases were collected from these households by an interview schedule.  Adult mosquitoes were also collected from the premises. Health education and demonstration classes on potential breeding sites of Aedes mosquito and methods of eliminating at household and community level were undertaken. Post intervention larval survey was also done.  


Results: Baseline larval indices showed that all the indices i.e HI : 13.09%, CI: 5.38% and BI: 15.4%  were high in the month of June and another peak of larval indices were seen in the month of November 2019 (HI:10%, CI : 7.3%, and BI :10%) Total number of self-reported fever cases were also high during the month of June (208) and July(195).  The post intervention larval indices showed a considerable reduction in Breteau index from 10% to 7.5% in the month of November 2019 and in the month of February before intervention the BI  was 10%  and after intervention in Feb 2020 BI came to 2.5% . 


Conclusion: There was a significant reduction in larval indices after an educational intervention.
