Dengue fever (DF) is a vector-bore infectious disease that can infect humans, and has been recognized as a global public health threat, with significant morbidity and mortality rates.
To describe the epidemiological profile of DF in China during 2004-2016, the morbidity data of DF by age-group, season (different months) and geographic location (different provinces) were obtained from the public health science data center of China for subsequent epidemiological analysis.
The results showed that the incidence of DF shows striking annual variations, and two large outbreaks occurred in 2006-2007 and during 2012-2015. The results of the average morbidity rates (cases/100,000 population) for human DF indicated that among all dengue fever cases, Guangdong in southern area of China had the highest rates (3.8160 cases/100,000 population), followed by Yunnan (0.6614 cases/100,000 population), Fujian (0.3463 cases/100,000 population) and Guangxi (0.1474 cases/100,000 population). Epidemic peaks occurred in late June and early November, and the incidence rate among middle-aged people (30-45 years old) was relatively high, followed by rates among 15-29 and 45-59 age groups.
In this study, we demonstrated the epidemiological profile of DF circulating in China and revealed the geographic distribution, dynamic transmission, seasonal asymmetries and age distribution, which will provide guidelines on the prevention and control of DF in China. The present investigation is useful in the risk assessment of DF transmission, to predict DF outbreaks and the prevention and control strategies should be used along with surveillance to reduce the spread of DF in China.
登革热（DF）是一种由蚊子传播的传染病，可以感染人类，已被认为是全球公共卫生威胁，具有较高的发病率和死亡率。
为描述 2004-2016 年中国登革热的流行病学特征，从中国公共卫生科学数据中心获取了按年龄组、季节（不同月份）和地理位置（不同省份）划分的登革热发病率数据，进行流行病学分析。
结果表明，登革热的发病率呈明显的年度变化，2006-2007 年和 2012-2015 年发生了两次大暴发。平均发病率（每 10 万人中的病例数）结果表明，在所有登革热病例中，中国南部的广东省发病率最高（3.8160 例/10 万人），其次是云南省（0.6614 例/10 万人）、福建省（0.3463 例/10 万人）和广西壮族自治区（0.1474 例/10 万人）。流行高峰出现在 6 月底和 11 月初，发病率较高的人群为中年人（30-45 岁），其次是 15-29 岁和 45-59 岁年龄组。
本研究展示了中国流行的登革热的流行病学特征，揭示了其地理分布、动态传播、季节性不对称和年龄分布，为中国登革热的预防和控制提供了指导。本研究有助于评估登革热传播的风险，预测登革热疫情，并结合监测采取预防和控制策略，以减少中国登革热的传播。
