Distribution and Abundance of Dengue Vector(S) Mosquito and Their Breeding Preferences in Five Selected Administrative Wards of Dhaka North City Corporation, Bangladesh
Journal Title: Public Health Open Access - Year 2022, Vol 6, Issue 2
Abstract
Dengue fever (DF) and Dengue haemorrhagic fever (DHF) is the most significant arising arboviral disease which is spread from dengue virus infection. Aedes aegypti and Aedes albopictus are the known vectors of dengue virus worldwide. A house based entomological survey was conducted to identify the distribution, abundance of dengue vector(s) mosquitoes and their preferable breeding sites in five selected wards at Dhaka North City Corporation, during July to December 2019. Stegomyia indices were calculated using the exact binomial test. Association between climatic factors and Aedes species abundance were also studied. The highest prevalence of Aedes mosquitoes were found in July. We did not found any Ae.albopictus during the study period. The overall house index (HI), container index, and Breteau index were found 20, 2 and 31 respectively, during the survey period. The present study did not find any significant association (p > 0.05) with meteorological factors (mean temperature, lag rainfall & relative humidity) and the density of Aedes mosquitoes. It is not possible to get an exact idea of the dengue outbreak through a short-term Aedes mosquito survey. So, this study suggests year-long mosquito surveillance program to acquire more conception of dengue transmission and how dengue vector(s) species abundance playing the role.
