Climate Variability and Dengue Hemorrhagic Fever in Bandar Lampung, Lampung Province, Indonesia

Climate impacts on health through ecosystem changes, namely the increased risk of vector-borne diseases through the distribution and abundance of vector organisms. The mean incidence of DHF (IR per 100,000 population) in Bandar Lampung from 2007 to 2018 was 104.20 (40.49-245.48), far exceeding the provincial (41.70) and national average (51.36). The study aims to determine the effect of climate, namely rainfall, temperature, and humidity of the number of dengue cases. Data sources are from the Bandar Lampung Health Office and the Geophysics Climatology and Geophysics Agency of Lampung Province. In data processing, daily climate data is converted into monthly and annual data, while the monthly DHF case data becomes annual. The analysis was carried out in stages to obtain a strong relationship between climate variables and the number of dengue cases. The analysis techniques used are mean, minimum-maximum, product-moment correlation, and multiple linear regression. The results showed that the average number of monthly dengue cases in 2007-2018 was 79.19 cases (8-552 cases), rainfall 6.68 mm (0.00-24.10 mm), temperature 28.120C (24.00- 29,300C), and humidity 79.71% (73.90-86.30%), while the climate factor associated with the incidence of DHF was rainfall (p-value = 0.022), with an effect of 19.0%. This research provides preliminary evidence about the influence of climate factors on dengue transmission
