Dengue Hemorrhagic Fever and Its Correlation with The Weather Factor In Bandar Lampung City: Study From 2009-2018

Dengue Hemorrhagic Fever (DHF) is the most serious vector-borne disease in Bandar Lampung. Dengue virus and its vector Aedes Aegypti are sensitive to weather changes, especially rainfall, temperature and humidity. This research objective was to determine the correlation between weather factors and dengue cases using the period 2009-2018. Data obtained from reports on the number of monthly cases of the in Health Office of Bandar Lampung City and daily climate reports from the Meteorology, Climatology and Geophysics Agency, which are converted into monthly averages. We found that the highest DHF cases were in January, February and March. Rainfall has a positive correlation with the number of dengue cases in 2011 (p-value = 0.012) and 2015 (p-value = 0.020). Each year, the rainy period precedes the start of the increase in dengue cases. Temperature has a negative correlation in 2014 (p-value = 0.036). Humidity has a positive correlation in 2014 (p-value = 0.024) and 2015 (p-value = 0.018). Rainfall has the greatest influence in relation to DHF cases in Bandar Lampung City (36.9%). These findings provide empirical evidence regarding the correlation between weather factors and DHF transmission and are expected to provide a scientific basis for the prevention and control of DHF.
