CLIMATE AND MOSQUITO-BORNE DISEASES IN BANJARNEGARA: PROSPECT FOR AN EARLY WARNING SYSTEM

Abstract

Dengue and malaria are mosquito-borne diseases that are transmitted through the bites of Aedes aegypti and Anopheles mosquitoes. Climate change may have an impact on the development of these mosquito vectors because weather conditions have an impact on metabolism, growth, development, and population. This study aimed to examine the relationship between climate with dengue and malaria incidence in Banjarnegara Regency. This research used secondary data with a cross-sectional approach. The research variables were climate data (temperature, humidity, rainfall, and wind velocity) recorded at the Banjarnegara Class III Meteorology, Climatology and Geophysics Agency (BMKG), while data on dengue and malaria cases during 2010-2019 were obtained from the Banjarnegara Health Office. Data analyses were univariate and bivariate, which were preceded by a data normality test. The results showed that the incidence of dengue and malaria in Banjarnegara tended to decrease during the period 2010 to 2019. Temperature and rainfall were correlated with the incidence of dengue (11.9%), while humidity and wind velocity were correlated with malaria (28.6%). Linear regression analysis shows that the climatic factor that can be used to predict the dynamics of dengue transmission is temperature, while that of malaria is wind velocity. This model can be used to help mitigate dengue and malaria transmission by determining the timing of prevention and providing infrastructure for dengue and malaria control.
