Hubungan antara Perilaku Kesehatan dengan Kejadian Demam Berdarah Dengue (DBD) di Kampung Nelayan Seberang Desa Paluh Kurau Kecamatan Hamparan Perak Kabupaten Deli Serdang

Abstract

Dengue fever (DHF) is one of the fastest spreading diseases in the world, caused by the dengue virus and transmitted through the bite of Aedes sp. This study aims to evaluate the relationship between health behavior and the incidence of DHF in Kampung Nelayan Seberang, Paluh Kurau Village, Hamparan Perak District, Deli Serdang Regency. The study used a quantitative approach with a cross-sectional design conducted from April to May. The study population was all residents of Kampung Nelayan Seberang, with a sample of 50 respondents selected using purposive sampling technique. Primary data were collected through observation, interviews, and documentation, then analyzed descriptively and analytically using the Chi-square test. The results showed that the presence of mosquito larvae had a significant relationship with the incidence of DHF (p-value = 0.03), where 85.71% of houses with mosquito larvae experienced DHF, while only 14.29% of houses without larvae were affected. Fogging proved to be the most effective, with 100% of the houses that had it done being free from DHF. In contrast, spraying mosquito repellent was effective in 52% of homes, anti-mosquito lotion in 70%, and sowing larvicide in 68%. The frequency of draining containers more than once a week reduced the risk of the presence of larvae compared to homes that never drained containers (42.8%). This study recommends increasing community education programs on the importance of mosquito nest control, regular fogging, and strict monitoring of high-risk environments to effectively reduce the spread of DHF.
