Clinical Epidemiological Investigation of Canine Influenza in Guangxi from 2013 to 2015

针对2013年-2015年广西11个地级市的宠物犬群进行犬流感调查，发现钦州犬流感感染的阳性率高达40％，除百色和玉林外，其余的阳性率在14．29％～34．29％之间，结果表明犬流感在广西呈普遍流行态势。此外，对不同品种、性别和生长阶段的宠物犬感染CIVs进行了调查分析。结果发现，任何品种和性别的宠物犬都可以感染犬流感病毒，其中青年阶段（6月龄～2岁）的犬最为易感。2015年的调查中，成年犬（2岁～7岁）成为潜在的易感群体。结果为更好地指导宠物医生采取有效的措施控制疾病发生，从而切断宠物犬作为中间传播者的作用，为防控人类大流感的暴发提供了间接帮助。
