Hence, an investigation was carried out to find out epidemiological and entomological reasons behind the outbreak.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n An entomological survey was carried out in 24 wards of Port Blair Municipal Council (PBMC) area, epidemiological data of last six years (January\u2013December 2017\u20132021 and January\u2013October 2022) and patient details of the year 2022 were collected. Both the epidemiological and entomological data were analyzed concerning time and place.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n During this outbreak period tyres (22.4%) came out as a major breeding habitat followed by small discarded materials (17.5%), metal drums (15.3%), and plastic drums (11.7%). In rainy season, peri-domestic breeding (55%) was more than the domestic breeding (45%) habitat.\n Ae. aegypti<\/jats:italic>\n had a high preference for indoor large containers (100-1000 L) like plastic tank, metal drum and cement tank whereas\n Ae. albopictus<\/jats:italic>\n prefers to breed in medium sized plastic container (20\u2013100 L) and outdoor water receptacles like tyres, flower pots, and domestic discarded materials.\n <\/jats:p>\n <\/jats:sec>\n \n Interpretation & conclusion:<\/jats:title>\n By source reduction, indoor space spray and outdoor fogging, vector density was controlled which curtailed the transmission and within eight weeks a decreasing trend of dengue cases was noticed. A regular entomological survey is crucial to know the seasonality and key breeding habitats of the vector for proper planning of vector control.<\/jats:p>\n
