BACKGROUND: Globally, dengue, Zika virus, and chikungunya are important viral mosquito-borne diseases that infect millions of people annually. Their geographic range includes not only tropical areas but also sub-tropical and temperate zones such as Japan and Italy. The relative severity of these arboviral disease outbreaks can vary depending on the setting. In this study we explore variation in the epidemiologic potential of outbreaks amongst these climatic zones and arboviruses in order to elucidate potential reasons behind such differences. METHODOLOGY: We reviewed the peer-reviewed literature (PubMed) to obtain basic reproduction number (R(0)) estimates for dengue, Zika virus, and chikungunya from tropical, sub-tropical and temperate regions. We also computed R(0) estimates for temperate and sub-tropical climate zones, based on the outbreak curves in the initial outbreak phase. Lastly we compared these estimates across climate zones, defined by latitude. RESULTS: Of 2115 studies, we reviewed the full text of 128 studies and included 65 studies in our analysis. Our results suggest that the R(0) of an arboviral outbreak depends on climate zone, with lower R(0) estimates, on average, in temperate zones (R(0) = 2.03) compared to tropical (R(0) = 3.44) and sub-tropical zones (R(0) = 10.29). The variation in R(0) was considerable, ranging from 0.16 to 65. The largest R(0) was for dengue (65) and was estimated by the Ross-Macdonald model in the tropical zone, whereas the smallest R(0) (0.16) was for Zika virus and was estimated statistically from an outbreak curve in the sub-tropical zone. CONCLUSIONS: The results indicate climate zone to be an important determinant of the basic reproduction number, R(0), for dengue, Zika virus, and chikungunya. The role of other factors as determinants of R(0), such as methods, environmental and social conditions, and disease control, should be further investigated. The results suggest that R(0) may increase in temperate regions in response to global warming, and highlight the increasing need for strengthening preparedness and control activities.
