Dengue outbreak in Bhilai, Chhattisgarh: Entomological investigation and community awareness
Keywords:Dengue, Mosquito Vectors, Larva, Community Participation, Aedes
Dengue is the most common arboviral infection worldwide. This study aimed to determine the entomological and community-related factors involved in dengue spread during the outbreak in Bhilai, Chhattisgarh, 2018. This was a cross-sectional study. The household survey was done to find out the vector responsible for disease transmission and favourable breeding containers. Susceptibility of larvae towards the larvicide being used was carried out. A questionnaire-based survey was undertaken to find out the awareness of residents in the area towards dengue. House index, Container index, and Breteau index were 92.31, 33.14 and 123.34, respectively. Larvae were susceptible to the larvicide being used by the local health department. A high number of wet containers available were contributing to high vector breeding. Community awareness was low in the affected area. Water storage practices and conducive climatic conditions lead to increased vector breeding.
