目的了解涉禽场所外环境甲型H7N9禽流感病毒分布情况,为防控工作提供依据。方法采集永嘉县活禽养殖场和农贸交易市场鸡(鸭)的不同种类标本,检测甲型H7N9禽流感病毒。结果 2013年8—12月共检测955标本,检出甲型H7N9禽流感病毒阳性13份,阳性率为1.36%;其中检测鸡标本631份,阳性率2.06%;鸭标本324份,阳性率0.00%;两者差异有统计学意义(P<0.05)。53家涉禽场所甲型H7N9禽流感病毒阳性率为9.43%。活禽养殖场和农贸市场鸡标本阳性率分别为2.17%和1.85%,两者差异无统计学意义(P>0.05)。不同月份鸡标本阳性率比较,差异有统计学意义(P<0.05)。结论永嘉县涉禽环境中存在H7N9禽流感病毒,可能对人存在潜在感染的危险。
Objective To understand the distribution of influenza A (H7N9) virus in the environment outside wading birds and provide basis for prevention and control. Methods Different types of samples of chicken (duck) from live poultry farms and farmers markets in Yongjia County were collected to detect the H7N9 influenza A virus. Results A total of 955 specimens were detected from August to December in 2013, and 13 positive samples were obtained from the H7N9 strain of avian influenza virus, the positive rate was 1.36%. Among them 631 chicken samples were detected, the positive rate was 2.06%. The positive rate was 0.00 %; The difference between the two was statistically significant (P <0.05). The positive rate of type A H7N9 bird flu in 53 Wading Habitat sites was 9.43%. The positive rates of chicken samples in live poultry farm and farmer’s market were 2.17% and 1.85%, respectively, with no significant difference (P> 0.05). The positive rates of chicken samples in different months were significantly different (P <0.05). Conclusion There is H7N9 avian influenza virus in Wading environment of Yongjia County, which may pose a potential risk of infection to humans.
