摘要

目的 分析航空旅客数、气象因素对广东省登革热本地病例数的影响,为登革热的精准防控提供科学依据。方法 收集2015-2020年登革热逐月发病数及同期的气象因素、以广东省为目的地的东南亚航空旅客数,拟合广义相加模型分析气象因素及航空旅客数对广东省本地登革热传播的影响。结果 登革热本地病例的发生呈现明显的时间趋势(F=74.651,P<0.001),高发月份为9-11月;直达航空旅客数、前1个月的月平均最低气温与登革热本地病例数之间呈近似线性的正向关系(F=651.121,P<0.001;F=8.297,P<0.001);前3个月的月降水量、前3个月的月平均相对湿度与登革热本地病例数之间呈现倒“U”形关系(F=100.567,P<0.001;F=55.938,P<0.001),阈值分别为295 mm和70.93%。结论 直达航空旅客数、月平均最低温度、月降水量、月平均相对湿度均对登革热本地传播有调节作用。在登革热防控策略中加强对东南亚入境旅客的监测并考虑季节性气象变化,以提高防控措施的针对性和有效性。

Abstract

Objective To analyze the impact of the volume of airline travelers and meteorological factors on the scale of local cases of dengue fever in Guangdong Province, China, so as to provide scientific evidence for targeted prevention and control of the disease. Methods The monthly data of dengue cases, meteorological factors, and the volume of air passengers from Southeast Asia to Guangdong from 2015 to 2020 were collected. Generalized additive model was utilized to analyze the effects of meteorological factors and the volume of air passengers on the local transmission of dengue fever in Guangdong. Results The occurrence of local dengue cases exhibited significant temporal variations (F=74.651, P<0.001), with the highest number of cases occurring from September to November. The volume of no-stop air passengers and the one-month lagged average minimum temperature generally showed linear positive correlations with local dengue cases (F=651.121, P<0.001; F=8.297, P<0.001). Additionally, the three-month lagged monthly precipitation and average relative humidity demonstrated an inverted U-shaped relationship with local dengue cases (F=100.567, P<0.001; F=55.938, P<0.001), with thresholds of 295 mm and 70.93%, respectively. Conclusions The volume of no-stop air passengers, average monthly minimum temperature, monthly precipitation, and monthly average relative humidity all play a regulatory role in the transmission of local dengue fever. Strengthening the surveillance of inbound passengers from Southeast Asia and considering seasonal meteorological variations can enhance the specificity and effectiveness of dengue prevention and control strategies.
