Abstract

Dengue outbreak is repeatedly being reported in Bihar. In 2015, many districts were affected with the disease. Outbreak investigation was carried in Patna, Bhojpur, Aurangabad and Gaya district Bihar to determine the causes of outbreak. Epidemiological, Entomological and Socio-environmental survey was done to know the reasons of outbreak and to suggest remedial actions. Analysis of data collected at the State level was also done. Disease afflicted almost all age groups but the incidence was more in 21-30 age group. Males were more affected than females. Vector and larval surveillance in the affected areas were positive. Per Man Hour density of Aedes aegypti was also above the critical limit of transmission. High House and Briteau Index in all the four districts posed significant risk of outbreaks. Around 70% of the population was aware about the term Dengue; however knowledge about various aspects were lacking. Around 80% of the population stored water at home. Only 10% of the population cleaned/changed the water stored in domestic or peri-domestic containers. Majority of the cases were reported in monsoon and post-monsoon season. Community support and participation is also crucial for the prevention of future outbreaks and improving the health and well being of population in the districts.

Keywords: Dengue, Outbreak, Epidemiological, Entomological.
