摘要/Abstract

摘要： 目的分析2020－2021年我国12个省（自治区、直辖市）媒介伊蚊生态学监测结果，为媒介伊蚊传播疾病风险评估、预测预警及控制提供科学依据。方法收集我国12个省（自治区、直辖市）媒介伊蚊专项调查点媒介伊蚊幼蚊及成蚊密度调查资料，利用SPSS 18.0软件进行统计分析。结果 2020－2021年海南、浙江和湖南省平均布雷图指数（BI）>10.00，广西壮族自治区（广西）、云南、河南和山东省平均BI>5.00；广西、广东、海南和山东省（自治区）平均诱蚊诱卵指数（MOI）>5.00；河南、湖北和山东省平均帐诱指数≥2.00只/（顶·h），广西、广东、海南、云南、福建和湖南省（自治区）平均帐诱指数>1.00只/（顶·h）。Ⅰ类省份［广东、海南、广西、福建、云南和浙江省（自治区）］与其他类型省份平均BI、MOI和帐诱指数比较差别无统计学意义（t=0.766、1.030、-0.745，均P>0.05）。2020－2021年，除广东、广西、云南、山东省（自治区）平均BI高于2017－2019三年平均水平外，其他省份BI均低于这3年的平均水平。媒介伊蚊在广东、海南、广西、云南4省（自治区）调查点全年有活动，在福建、浙江和湖北等省（自治区）3－12月有活动，在重庆、山东和河南等省（直辖市）4－11月有活动，在江西省4－12月有活动。BI和MOI研究结果在云南、广西和湖北省（自治区）存在一定差别。研究期内，发生登革热暴发和本地病例的地区媒介伊蚊BI均>5.00，云南省瑞丽市、广西梧州市岑溪市及广东省中山市三角镇BI>10.00；广西岑溪市帐诱指数>2.00只/（顶·h）。结论 2020－2021年我国出现登革热本地病例省份媒介伊蚊平均密度较高，不同地区媒介伊蚊密度差异存在时空异质性。建议我国登革热本地传播地区适当调整媒介伊蚊监测时间，继续加强媒介伊蚊监测和风险评估，系统梳理媒介伊蚊生态学调查结果，为我国媒介伊蚊监测方案修订完善及媒介伊蚊传播疾病暴发控制提供科学依据。

Abstract: Objective To analyze the ecological surveillance results of Aedes vector in 12 provinces (autonomous regions or municipalities) in China in 2020-2021, and to provide a scientific basis for risk assessment, prediction, early warning, and control of Aedes-borne diseases. Methods The surveillance data of larval and adult Aedes densities at the special investigation sites of Aedes vector in 12 provinces (autonomous regions or municipalities) in China were collected and statistically analyzed by SPSS 18.0 software. Results In 2020-2021, the mean Breteau index (BI) was >10.00 in Hainan, Zhejiang, and Hunan provinces and >5.00 in Guangxi Zhuang Autonomous Region (Guangxi) and Yunnan, Henan, and Shandong provinces. The mean mosq-ovitrap index (MOI) was >5.00 in Guangxi, Guangdong, Hainan, and Shandong. The mean net trap index was ≥2.00 mosquitoes/net·hour in Henan, Hubei, and Shandong and >1.00 mosquito/net·hour in Guangxi, Guangdong, Hainan, Yunnan, Fujian, and Hunan. There were no statistical differences in BI, MOI, and net trap index between class I provinces (Guangdong, Hainan, Guangxi, Fujian, Yunnan, and Zhejiang) and other classes of provinces (t=0.766, 1.030, and -0.745, all P>0.05). The mean BI in 2020-2021 was higher than that in 2017-2019 in Guangdong, Guangxi, Yunnan, and Shandong, but lower than that in the three years in other provinces. The Aedes vector was found to be active throughout the year at the investigation sites in Guangdong, Hainan, Guangxi and Yunnan, from March to December in Fujian, Zhejiang, and Hubei, and from April to November in Chongqing municipality, Shandong and Henan, and from April to December in Jiangxi. The results of BI and MOI were inconsistent in Yunnan, Guangxi, and Hubei. During the study period, the BI of Aedes vector was >5.00 in areas where dengue outbreaks and local cases occurred, and >10.00 in Ruili city in Yunnan, Cenxi city of Wuzhou in Guangxi, and Sanjiao town of Zhongshan in Guangdong; the net trap index in Cenxi city of Guangxi was >2.00 mosquitoes/net·hour. Conclusion In 2020-2021, the mean Aedes density in the provinces with local cases of dengue fever in China was high, with spatio-temporal heterogeneity among different regions. It is suggested that in the local transmission areas of dengue in China, it is necessary to adjust moderately annual surveillance periods, to continuously strengthen Aedes vector surveillance and risk assessment, and to systematically sort out the ecological investigation results of Aedes vector, so as to provide a scientific basis for the revision and improvement of Aedes vector surveillance scheme and the outbreak control of Aedes-borne diseases in China.
