Background: Dengue has emerged as one of the most deadly vector borne infections in the WHO South-East Asia Region, which contributes to more than half of the global burden. About 52% of the global population at risk resides in this region. The present study was conducted to examine the trends of reported dengue cases in South Zone, SDMC and strategies utilized to decrease the incidence of Dengue cases.

Materials and methods: This was a retrospective study where confirmed dengue cases reported from 24 wards in South Zone, S.D.M.C., New Delhi from 2013 to 2017 were studied.  Case Definition was taken as per guidelines of National Vector Borne Disease Control Programme, Government of India. Strategies leading to the decrease in were ascertained by examining the annual reports. Entomological Indices were calculated for each year and correlation was studied.

Results: A steady decline was observed in the incidence of dengue cases, barring 2015 when there was an outbreak due to a different serotype. The total number of reported cases in 2013 was 343 in 2013, which have decreased to 189 in 2017. It was observed that multiple strategies have contributed for decrease in the incidence of dengue fever. There has been focus on community awareness and participation, involvement of school children by organizing rallies and regular talks in residential areas. Reading messages on dengue prevention during morning assembly, implementation of Dengue Home Work Card scheme, sensitization of public by mass SMS, broadcasting messages on FM radio etc. have all contributed positively. There have been regular meetings with stake holder departments.

Conclusions: Community participation and inter-sectoral co-ordination can go a long way in fighting the war against vector borne infections. Each member of the community should take ownership and keep a check on breeding in his/her immediate vicinity.
