Description Study design:  Cross-sectional (Household / Key informant survey)

Study sites & sample:
4 Cities (Delhi, Bengaluru, Chennai & Trivandrum). Two wards/zones will be selected based upon the occurrence of new cases of Dengue and Chikungunya as High risk and Low risk areas respectively in the said cities. Purposive sample survey of 750 household will be done on each of these zones/wards.
Quarterly Reports (5-10 lines) Study was completed in March 2012. In this study we observed a significant difference between the two high and low endemic study areas in Chennai in case of only few parameters.It was interesting that indoor breeding of the vector was common in both the areas as was evident from the larval collections from water storage containers inside the households.
