Abstract

Introduction: Dengue hemorrhagic fever (DHF) is a disease caused by dengue virus infection characterized by muscle pain, fever, and/or joint pain. More than 50% of the world^s population lives in dengue-endemic areas. These areas account for more than half of the global disease burden. Environmental conditions, climate, geography, socioeconomics, and cultural behavior of people from various places are elements that allow for all thresholds for predicting dengue disease. Geographic environmental factors, such as rainfall, temperature, and humidity, play a crucial role in the transmission of dengue infection. Therefore, this study aims to analyze the geographic environmental risk factors for the incidence of dengue infection in Palembang City.
Methods: This study used a quantitative method with a descriptive research design in Palembang City. Rainfall, temperature, and humidity were the independent variables, while dengue infection incidence was the dependent variable. The unit of analysis was dengue infection incidence in Palembang City between 2021 and 2023.
Results: In 2021, the highest number of cases was recorded in November and the lowest in July. In 2022, the highest number of cases was recorded in January, while the lowest number was recorded in February. In 2023, the highest number of cases occurred in February and December, while the lowest number of cases was recorded in September.
Conclusion: There is no similar pattern between total cases and temperature and humidity in the same month. There is a similar pattern between rainfall and total cases in the following month, known as Lag-1.
