ASSESSMENT OF VECTOR-BORNE DISEASE RISKS: LARVAL SURVEY FOR IDETIFICATION OF DENGUE AND OTHER FEVER CASES AT YALAVATTI VILLAGE GADAG DISTRICT

Background: Yalavatti Village in Karnataka's Gadag district has seen a rise in fever cases, with symptoms linked to dengue. The investigation aimed to assess the potential epidemic, identify mosquito breeding sites, and recommend control measures. Quick action was necessary to prevent the escalation of dengue cases, and public awareness efforts were initiated to prepare for future outbreaks. Objectives 1. Assessment of Fever cases in Yalavatti Village. 2. Assessment of Larval Survey for the presence of Aedes mosquito larvae in water containers and pinpoint key breeding sites linked to disease transmission. Methods: A Cross-Sectional study in Yalavatti Village assessed dengue through house-to-house surveys and entomological surveys, conducted by seven specialized groups. These groups focused on fever case reporting, mosquito larvae sampling, data entry and analysis, environmental assessment, public health education, and medical follow-up. Data was analyzed to determine disease prevalence and mosquito breeding density, guiding effective control measures. Results: The investigation revealed that 6.4% of households in Yalavatti Village reported fever cases, with clinical symptoms indicative of dengue. The entomological survey found Aedes mosquito larvae in 9% of households, primarily in domestic water containers, highlighting significant mosquito breeding sites. Conclusion: The outbreak investigation in Yalavatti Village confirms a localized incidence of dengue and chikungunya, driven by widespread mosquito breeding in domestic water containers. The presence of Aedes larvae in 9% of households and fever cases in 6.4% underscores the critical need for immediate vector control measures and enhanced public health initiatives. Addressing these issues promptly will be essential to curbing the current outbreak and preventing future occurrences.
