To analyze dengue fever outbreaks in China, Zhejiang Province, and a local region to provide a scientific basis for early warning surveillance and the prevention and control of dengue epidemics.
This retrospective study examines dengue fever data from China and Zhejiang Province over the past decade, including incidence, mortality, seasonal distribution, age characteristics, and regional distribution. Local data from the past decade were also analyzed.
Over the last ten years, the average annual incidence rate of dengue fever in China has been 0.7764 per 100,000 individuals, with a mortality rate of 0.000945 per 100,000. In the same period, the incidence rate in Zhejiang Province was 0.4546 per 100,000, with no fatalities reported. Dengue fever cases in both China and Zhejiang Province are primarily seen during the summer and autumn seasons. Between 2014 and 2020, cases were documented across all age groups in China, demonstrating an age-specific pattern in the annual average incidence rate, with rates initially increasing to peak in young adults and subsequently declining with advancing age. The highest rates were noted in the 20-29.9 and 30-39.9 age brackets. With the exception of Tibet, all regions in China have recorded cases, with Guangdong, Yunnan, Fujian and Zhejiang in the southern part of the country being the main high-incidence areas. In Cangnan County, 30 cases of dengue fever were reported over the past decade, predominantly affecting imported cases, males, and young to middle-aged adults.
Dengue fever cases are rising in China, particularly in southern regions. 15 to 50 years old people are most affected. There is a pressing need for region-specific strategies to mitigate the impact of dengue fever, particularly in high-incidence areas.
分析中国、浙江省及某局部地区的登革热疫情，为登革热疫情的早期预警监测及防控提供科学依据。
本回顾性研究调查了中国和浙江省过去十年的登革热数据，包括发病率、死亡率、季节分布、年龄特征和地区分布。还分析了过去十年的局部数据。
在过去十年中，中国登革热的年平均发病率为每10万人0.7764例，死亡率为每10万人0.000945例。同期，浙江省的发病率为每10万人0.4546例，无死亡报告。中国和浙江省的登革热病例主要出现在夏秋季节。2014年至2020年期间，中国各年龄组均有病例记录，年平均发病率呈现出特定的年龄模式，发病率最初在年轻人中上升至峰值，随后随着年龄增长而下降。发病率最高的年龄段为20 - 29.9岁和30 - 39.9岁。除西藏外，中国所有地区均有病例记录，南部的广东、云南、福建和浙江是主要的高发病区。在苍南县，过去十年报告了30例登革热病例，主要影响输入性病例、男性以及中青年成年人。
中国登革热病例呈上升趋势，尤其是在南部地区。15至50岁的人群受影响最大。迫切需要制定针对特定地区的策略来减轻登革热的影响，特别是在高发病区。
