【摘要】：正鴨流感是由高致病性禽流感H5亞型病毒感染引起的一種鴨的烈性病,在生物安全和免疫缺失的地區(qū),其感染率和發(fā)病率均很高,尤其是2~6周齡的商品鴨極易感染,并可引起嚴(yán)重的呼吸道癥狀和神經(jīng)癥狀,再加上后期的細(xì)菌繼發(fā)感染,常常導(dǎo)致大量的死亡,死亡率往往在5%~40%,甚至全群覆沒,經(jīng)濟(jì)損失十分嚴(yán)重。為有效預(yù)防和控制鴨流感的發(fā)生,項(xiàng)目組在進(jìn)行流行病學(xué)調(diào)查
[Abstract]:Duck influenza is a severe disease of ducks caused by H5 subtype of highly pathogenic avian influenza virus. The infection rate and incidence rate of duck influenza is very high in the areas of biosafety and immune deficiency, especially in the commercial ducks of 2 to 6 weeks of age. It can cause serious respiratory symptoms and neurological symptoms, plus secondary infection of bacteria in the later stage, which often leads to a large number of deaths. The mortality rate is often at 540%, or even the whole group is destroyed, and the economic losses are very serious. To effectively prevent and control duck influenza, the project team is conducting an epidemiological survey
