Poster summary

PURPOSE The impact of climate change on the distribution of dengue rises controversy and debate; despite the existence of evidence about the effect of changes in certain environmental variables have on its epidemiology. MATERIAL & METHODS We performed a systematic review. The study area was Africa. The disease under study was dengue and its vector Aedes. Standard terms for climate change and/or environmental factors were included in the search. The review protocol was registered in PROSPERO. RESULTS 19 studies met the inclusion criteria. 47% concluded that climate change is affecting the prevalence and/or incidence of dengue, compared to 42% that did not find such a relationship. According to 37%, the prevalence of dengue will increase in the coming decades, while it will decrease according to 11%. 63% showed an increase in the spread of dengue. Temperature and rainfall were the most frequently analyzed environmental factors.
