Dengue is transmitted in the Caribbean primarily through a mosquito vector called Aedes aegypti. Past studies have found that climate factors such as higher temperatures and increased precipitation affect the lifecycle and habitat of these mosquitoes. Likewise, changes in the Aedes lifecycle cause changes in dengue transmissions. Therefore, a thorough analysis of those climate factors would aid in understanding dengue transmissions. This study focused on how air temperature, humidity, precipitation, and sea-surface temperature (SST) affected the dengue epidemics of 1994 and 1998. Each climate factor was correlated with dengue outbreaks on a weekly basis. Precipitation, air temperature, and humidity showed weak relationships with dengue outbreaks. SST, however, showed an exponential relationship. A good exponential model was found for 1994, but was not appropriate for 1998. Instead, a regression tree was used to analyze 1998 SST and air temperature thresholds. The thresholds were around 27 - 30?C, which agreed with past studies. Qualitative analyses of tropical storm systems showed that storms did not have a strong impact on dengue transmissions. In general, the results demonstrated that except for SST, climate factors did not have a large effect on dengue transmissions, rather key social factors could be at play. Thus, for dengue prevention, the public health infrastructures should focus more on social problems and less on climate factors. Show less
