a massive outbreak of Dengue cases during 2012. Subsequently the rise in dengue cases was noticed during 2017 and
the incidence continues year after year in the State, with varying degree of intensity. So the Department of Public Health
&Preventive Medicine has taken up the matter seriously and initiated scientific analysis of the data and field studies were
under taken by involving the Institute of Vector Control and Zoonoses, Hosur. So under the guidance of the Director
of Public Health & Preventive Medicine and Joint Director of Institute of Vector Control and Zoonoses, a study on the
prevalence of dengue in Hosur Municipal Corporation area was taken up, since Hosur area in Krishnagiri district is reporting
dengue cases year after year with considerable proportion to the district. Utilizing the data available, field visits were
made during 2020 and 2021, the epidemiological and entomological parameter, were collected, analysed and it was felt
that there is an urgent need to carry out control activities on stratification of areas to minimize the displacement of health
state. The outcome of this exercise has helped to draw a stratification map of dengue for Hosur Municipal Corporation
area. The existing surveillances for Dengue case detection, treatment and follow up measures are discussed in this paper.
