THE RELATIONSHIP BETWEEN WEATHER FACTORS AND THE INCREASING DENGUE FEVER IN BANJAR REGENCY (2019-2024)

Abstract

Introduction: Dengue Hemorrhagic Fever (DHF) remains a significant public health issue, particularly in tropical and subtropical regions, and continues to rise at an alarming rate, often leading to outbreaks. Various factors contribute to the occurrence of DHF, including weather patterns. The objective of this study is to analyze the relationship between weather patterns and the incidence rate of DHF cases in Banjar Regency, South Kalimantan, from 2019 to 2024. Methods: This research employs quantitative techniques within an ecological framework. The data used are derived from the health profile of South Kalimantan Province from 2019 to 2024 and weather data from NASA. Data analysis used the Shapiro-Wilk test to assess data normality, followed by the Spearman correlation test to assess relationships between variables. Result: The Spearman correlation test showed a positive correlation between temperature and dengue fever cases (r = 0.44, p = 0.00). This shows that within the observed temperature range of 26–28°C, higher temperatures are associated with more dengue cases. Meanwhile, humidity (r = -0.39, p = 0.00) and rainfall (r = -0.25, p = 0.00) showed a negative relationship with DBD cases, indicating that higher humidity and rainfall were associated with fewer cases. Conclusion: It can be concluded that there is a significant relationship between weather patterns and the occurrence of dengue fever cases in Banjar Regency, South Kalimantan, from 2019 to 2024.
