Density of Aedes aegypti Larvae Based on the Entomological Index in Huidu Village, West Limboto District

Abstract

Dengue Hemorrhagic Fever (DHF) remains a significant public health problem as it frequently causes outbreaks and poses a risk of death. According to the World Health Organization (WHO) report as of April 30, 2024, more than 7.6 million dengue cases have been recorded worldwide, including 3.4 million confirmed cases, over 16,000 severe cases, and more than 3,000 deaths. This study is an observational research with a descriptive design aimed at assessing the density level of Aedes aegypti vectors through the calculation of the House Index (HI), Container Index (CI), Breteau Index (BI), Density Figure (DF), and Larvae-Free Index (ABJ). The examination was carried out by identifying the presence of larvae in water-holding containers without collecting larval samples. The results showed that the HI was 23% from 100 inspected houses, the CI was 2.9% from 800 containers examined, and the BI was 23% from 100 houses. Based on these findings, the Density Figure in Huidu Village, Limboto Barat Subdistrict, was 3.3, categorized as a Yellow Zone, which indicates a moderate level of vector transmission and requires vigilance. Mosquito breeding site eradication (PSN) efforts need to be strengthened through continuous 3M Plus activities, community empowerment in maintaining environmental cleanliness, and strengthening the role of larva monitoring cadres (Jumantik) to routinely inspect larvae presence in order to reduce the risk of dengue transmission.
