2009－2021年安徽省马鞍山市禽流感监测与分析

Surveillance for avian influenza in Maanshan, Anhui, 2009−2021

摘要

摘要:
目的通过分析2009—2021年马鞍山市禽流感外环境监测数据，提高禽流感监测效率，为人感染禽流感有效防控提供科学依据。
方法 2009—2021年分别对全市城乡活禽交易市场、规模养殖户、家禽散养户、家禽屠宰加工厂4类场所采集1602份外环境样本，运用实时荧光定量（RT-PCR）方法对样本进行禽流感病毒检测，对数据进行统计分析。
结果检测外环境标本1602份，禽流感阳性率为17.92%，阳性标本集中在冬季，主要来自城乡活禽市场样本，阳性率最高的是清洗禽类污水，阳性样本亚型以H9居多。
结论 2009—2021年马鞍山市活禽交易市场是人感染禽流感的高风险场所，冬春季尤需加强重点地区重点样本监测，落实市场各项卫生措施。

Abstract:
Objective To analyze the surveillance data of avian influenza virus in external environment in Maanshan from 2009 to 2021 and provide scientific evidence for the improvement of avian influenza surveillance and the prevention and control of human infection with avian influenza virus.
Methods A total of 1602 environment samples from 2009 to 2021 were collected from live poultry markets, large poultry farms, free range poultry farms and poultry processing plants, respectively, for the detection of the nucleic acid of avian influenza virus by real-time fluorescence quantitative PCR, and the results were analyzed statistically.
Results The positive rate of the nucleic acid of avian influenza virus was 17.92% in 1602 samples in external environment surveillance . The positive samples were mostly detected in winter and in live poultry markets. The positive rate was highest in poultry sewage samples. The main sub-type of influenza A virus was H9.
Conclusion Live poultry market is still the high risk place for human infection with avian influenza virus from 2009 to 2021. It is necessary to strengthen the surveillance for avian influenza virus in live poultry markets in key areas during winter-spring, and implement fully the hygiene managements measures in live poultry markets.
