Abstract | OBJECTIVES: TO STUDY THE SIGNIFICANCE OF ENTOMOLOGICAL SURVEILLANCE, THE HOUSE INDEX (HI), CONTAINER INDEX (CI), AND BRETEAU INDEX (BI) WERE DETERMINED TO ESTIMATE THE DEGREE OF A MAJOR DENGUE OUTBREAK IN TIRUNELVELI, TAMIL NADU, INDIA (LATITUDE: 8°42'N; Longitude: 77°42'E) in May 2012. METHODS: The HI, CI, and BI were determined in a primary health center (PHC) in the village of Maruthamputhur (Pappakudi taluk, Tirunelveli) by carrying out an antilarval (AL) work that involved door-to-door search for immature stages of Aedes spp. mosquitoes by trained field workers and volunteers. The work of field workers was evaluated by a junior and senior entomologist the following day. RESULTS: Before the AL work, the reported numbers of fever cases from Week 1 to 5 in Maruthamputhur were 211, 394, 244, 222, and 144 with two deaths. By contrast, after the AL work, these numbers were considerably reduced and there was no fever-related death (the HI was reduced from 48.2% to 1.6%, the CI from 28.6% to 0.4%, and the BI from 48.2 to 1.6). CONCLUSION:
