In Epidemiological Week 39, SKDR detected an increase in DHF cases in Ambopadang Village, Polewali Mandar, peaking at 44 cases in Week 41. A 1:1 unmatched case-control study (158 cases, purposive controls) was conducted by TGC, District Health Office, and FETP students using interviews, observations, and SKDR reports. Most cases were aged 21–30 (24.05%), 55.7% female. Risk factors were infrequent water container drainage (OR=2.10; 95% CI: 1.18–3.83) and poor knowledge of breeding prevention (OR=1.94; 95% CI: 1.12–3.35). The propagated outbreak was driven by environmental and behavioral factors, highlighting the need for education, vector control, surveillance, and intersectoral collaboration.
