flu epidemics

• While there is no evidence that it is possible to catch bird flu from eating chicken , consumers in asia stayed away from chicken when the bird flu epidemic spread across several asian countries
  当禽流感在几个亚洲的国家大恣司虐，但还没有证据来证明食用鸡肉可感染禽流感时，亚洲里的消费者已经停止食用鸡肉了。
• It has only emerged when chickens and turkeys are infected by strains of h5n1 of low pathogenicity from waterfowl , and that strain mutates into the highly pathogenic form within the poultry host , leading to an avian flu epidemic
  鸡只和火鸡从水鸟身上感染致命性低的h5n1病毒，病毒在家禽宿主体内变种成高致病性病毒，引致禽流感疫症爆发。
