![]() ![]() The effects of typhoons were stronger than those of tropical storms among various subpopulations. Men and the elderly were more vulnerable to the effects of tropical cyclones than the others. ![]() The attributable fraction was 6.31% (95% empirical confidence interval 1.96–10.16%). Tropical cyclones were associated with an increased number of dengue cases with the maximum risk ratio of 1.41 (95% confidence interval 1.17–1.69) in lag 0 week and cumulative risk ratio of 2.13 (95% confidence interval 1.28–3.56) in lag 0–4 weeks. The tropical cyclones were classified into two levels to compare the effects of different grades of tropical cyclones on the dengue incidence. The effect difference by sex and age groups was calculated to identify vulnerable populations. Proportion of dengue cases attributable to tropical cyclone exposure was calculated. A quasi-Poisson generalized linear model combined with a distributed lag non-linear model was conducted to quantify the association between tropical cyclones and dengue, controlling for meteorological factors, seasonality, and long-term trend. Weekly dengue case data, tropical cyclone and meteorological data during the tropical cyclones season (June to October) from 2015 to 2019 were collected for the study. This study aimed to examine the effects of tropical cyclones on the incidence of dengue and to explore the vulnerable populations in Guangzhou, China. Limited evidence is available about the association between tropical cyclones and dengue incidence. ![]()
