Climate change has emerged as a major global public health concern, significantly influencing the transmission dynamics of vector-borne diseases. This study aimed to assess the impact of climate change on vector-borne diseases and evaluate community-based surveillance and adaptation strategies among vulnerable populations. A community-based cross-sectional study was conducted among 300 participants selected through structured sampling methods. Data were collected on socio-demographic characteristics, environmental exposures, disease prevalence, awareness levels, preventive practices, and adaptation behaviours. Statistical analysis included descriptive statistics, Chi-square test, independent t-test, one-way ANOVA, Pearson correlation, binary logistic regression, multiple linear regression, factor analysis, principal component analysis, and structural equation modeling. Results showed that 39.3% of participants were affected by dengue, while significant associations were observed between disease incidence and flood exposure (p<0.001), water stagnation (p<0.001), poor sanitation (p=0.004), and mosquito breeding sites (p=0.002). Logistic regression identified water stagnation (OR=3.41) and flood occurrence (OR=2.87) as major predictors of disease occurrence. Higher awareness and adaptation strategy scores were associated with reduced disease burden. The study concludes that climate change substantially increases vector-borne disease risk, and strengthening community surveillance, environmental management, and adaptive public health interventions is essential for sustainable disease prevention.
