Introduction

Analysis of factors influencing the incidence of danguehemorrhagic fever (dbd) in semarang city. Analyze factors influencing Dengue Hemorrhagic Fever (DBD) incidence in Semarang City. Discover how water storage, knowledge, and mosquito eradication efforts impact disease spread and prevention.

Abstract

Dengue Hemorrhagic Fever is an infectious disease caused by acute viral infection, namely the dengue virus. Symptoms include fever for 2-7 days, accompanied by signs of bleeding, a decrease in the number of platelets (thrombocytopenia), and plasma leakage characterized by hemoconcentration. The aim of this study is to analyze the factors that most influence the incidence of dengue fever in the city of Semarang. This research uses a case control research design. The case population is all dengue sufferers, while the control population is people who are declared negative for dengue fever through microscopic examination of blood smears. The sample consisted of 2 groups, namely 45 respondents in the case group and 45 respondents in the control group, accompanied by the use of purposive random sampling techniques. The instrument uses a questionnaire sheet. Data analysis used the Chi Square test and Logistic Regression test. The results of the research show that there is a correlation between water storage, level of knowledge, efforts to eradicate mosquito nesting areas, use of anti-mosquito medication and behavior of hanging clothes with dengue cases (p-value < 0.05). Factors that influence the incidence of dengue fever are water storage, level of knowledge, and efforts to eradicate mosquito nests. It is necessary to carry out preventive efforts independently for each family member.

Review

This study provides a timely and relevant analysis of factors influencing Dengue Hemorrhagic Fever (DHF) incidence in Semarang City, an important public health concern in endemic regions. By employing a case-control research design, the authors aimed to identify specific determinants contributing to the disease's occurrence. The research is well-grounded in the understanding that DHF, an acute viral infection, is intricately linked to environmental and behavioral factors, and its objective to pinpoint the most influential factors is crucial for targeted prevention strategies. Methodologically, the study utilized a balanced sample of 45 DHF cases and 45 DHF-negative controls, with data collected via a questionnaire and analyzed using Chi-Square and Logistic Regression tests. While the sample size is modest, the application of both correlation and regression analyses allows for the identification of associations and more influential factors. The abstract mentions "purposive random sampling," which could benefit from further clarification in the full manuscript to detail how both purposive selection criteria and randomization were integrated into the sampling procedure. The findings reveal significant correlations (p < 0.05) between DHF cases and several variables, including water storage, knowledge levels, efforts to eradicate mosquito nesting areas, anti-mosquito medication use, and clothes hanging behavior. Critically, the study identifies water storage, knowledge, and mosquito eradication efforts as the primary factors influencing DHF incidence. The insights generated by this research are highly valuable for public health practitioners and policymakers in Semarang City. By highlighting specific modifiable factors such as water storage practices, knowledge about DHF, and active mosquito eradication, the study offers a clear direction for public health interventions. The concluding recommendation for independent preventive efforts by each family member underscores the importance of community engagement and household-level behavioral changes in curbing DHF. Future research could build upon these findings by evaluating the effectiveness of educational campaigns or community-based interventions designed to address these identified risk factors.
