Prevalence of Aedes Mosquitoes During the Dengue Transmission Season in Haridwar City of Uttarakhand State, India

Abstract

Introduction: Dengue is an acute viral illness caused by RNA virus of the family Flaviviridae and spread by Aedes mosquitoes. Common presenting features may range from asymptomatic fever to dreaded complications such as hemorrhagic fever and shock. So that an entomological investigation was conducted in the dengue-affected regions of Haridwar city, Uttarakhand, during the dengue transmission season. The purpose of the study was to determine the prevalence and distribution of Aedes mosquitoes and identify high-risk areas in Haridwar city for the control of dengue disease.
Methods: Adult mosquito were collected from all selected areas of city with the help of standard collection methods. A total of 1922 mosquito were collected.
Results: Out of 1922 residential premises, commercial establishments, and public places, only 244 localities were found positive for Aedes breeding. The House Index (HI), Container Index (CI), and Breteau Index (BI) in
residential areas were 12.40, 8.08, and 20.68, respectively, while the CI in commercial and public places was 33.50. Aedes aegypti followed by Ae. albopictus and Ae. vittatus was the most dominating species and found
in peri-domestic habitats. Larvae of Ae. aegypti were collected from junk materials, cemented tanks, pots, water tanks, mud pots, discarded tyres, tree holes, desert coolers, mani plant pots, plastic containers, trays of
domestic refrigerators, and flower pots. The average Man Hour Density (MHD) of Ae. aegypti, Ae. albopictus, and Ae. vittatus in residential areas were 10.77, 6.81, and 0.52, while in commercial/ official areas, they were
4.75, 7.95, and 1.68.
Conclusion: During the study, most of the areas showing high larval indices, may be the probable reason for the persistence of dengue in the city. Five species of Aedes mosquitoes, namely Ae. aegypti, Ae. albopictus, Ae.
vittatus, Ae. pseudotaeniatus, and Ae. thomsoni, were recorded Therefore there is a urgent need of more surveillance in dengye afftected areas as well as their surroundings.The vector control and all the preventive
measures need to be directed to eliminate the Aedes mosquito breeding
