RELATIONSHIP BETWEEN VENTILATION, LIGHT INTENSITY AND CONDITIONS FOR WATER RESERVOIRS IN THE HOUSE WITH THE OCCURRENCE OF DENGUE HEMORRHAGIC FEVER

Abstract


Background: Dengue hemorrhagic fever is an infectious disease caused by dengue virus and is transmitted through the bite of the Aedes aegypti or Aedes albopictus mosquito. Ventilation, light intensity and conditions for water resevoirs are physical controls to reduce the risk of outbreaks of DHF. Medan is one of the cities that is endemic for DHF, so that DHF cases continue to occur and even increase every year. In 2018 cases of dengue hemorrhagic fever have increased as many as 1490 cases with a death rate of 13 people.

Materials and Methods: This study aims to analyze the relationship between ventilation, light intensity and water storage conditions with the incidence of DHF. This type of research is descriptive, with case control design. The study population was 98 households, the study sample consisted of 49 cases and 49 controls. Data collection through observation and measurement. Data analysis methods include univariate analysis, bivariate analysis using chi square.

Result: The univariate analysis results demonstrated that the dengue hemorrhagic fever cases had higher prevalence rate in August (41%) and had dominant attack on 3-14 year old people (39%) as well as on females (59%). The bivariate analysis results indicated that lighting (OR= 9.474), ventilation (OR= 5.949) and condition of water reservoirs (OR= 4.769) were correlated with prevalence of dengue hemorrhagic fever.

Conclusion: The conclusion is there is a relationship between ventilation, light intensity and water storage conditions and the incidence of DHF. The community must pay more attention to this to reduce the risk of contracting dengue.

Keywords: Ventilation, light intensity, water reservoirs, DHF
