Dengue Fever Distribution, Climate and Visitors: A Study from Badung District of Bali, Indonesia

ABSTRACT As a national and international tourism destination, Badung district has recorded the highest dengue fever (DF) in Bali Province with multiple suspected influencing factors. This research presents the distribution of dengue fever (DF) incidence in Badung district and analyses its association with climate and visitors. The monthly data of DF surveillance, climate and reported number of visitors during January 2013 – December 2017 was analysed using Poisson Regression. 10689 new DF cases were notified from January 2013 to December 2017 while 2016 was recorded as the heaviest DF incidence. Monthly DF cases have positive association with average temperature, precipitation, humidity and local visitors. While negative association was shown between DF cases with foreign visitors. This study underlines the urgency to integrate climate and tourism for dengue fever control. Further study is recommended to take both factors together with population mobility at finer spatial and time unit of analysis.
