新流感二次危机 传播迷雾

　　

生物通报道，据Science Insider消息，猪流感H1N1再度袭击动物，阿根廷Buenos Aires省的一个猪场发现猪群感染新流感（H1N1）。

 

这是继加拿大Alberta传出有猪群感染新流感后，又一个爆出有动物群感染新流感的国家。

 

据Argentina食品安全委员会SENASA的发言人在6月25号的发言中表示，猪群中至少有5个以上的个体感染新流感，检测结果为阳性。目前，病毒的感染源的调查工作还在继续，暂时不清楚猪群是如何感染的新流感。

 

SENASA主任Jorge Amaya在接受电视访问时表示，事发的猪场已经有超过60天没有从其他猪场引进猪只了，所以可以排除猪—猪传播的可能性。SENASA的工作人员强烈怀疑该病毒由人—猪途径传播。

 

到26号为止，阿根廷的新流感感染人数不断上升，有1391人感染，22人死亡。

 

这也让人不得不担忧，如果流感疫情在人群和动物群相继爆发，其可能带来什么样的后果。笔者记起，采访香港大学管轶教授时，管轶表示，目前加紧监控动物流感势在必行。

 

可以说，目前国内流感疫情已经开始进入社区传播的阶段，形势严峻。当所有的资源和关注的目光都集中在人群的疫情时，是时候要关注动物的疫情，更要关注动物疫情以确保人的安全。

Swine Flu Strikes Hog Farm in Argentina

 

The A(H1N1) swine flu virus has struck a pig farm in Buenos Aires province in Argentina—the second known instance of the pandemic virus infecting pigs.

 

The outbreak was announced in a statement by Argentina’s food safety agency SENASA on Wednesday; yesterday, Dow Jones Newswires reported that at least five animals have tested positive for the virus so far. It’s not clear where the virus came from, but  “we have a very strong hypothesis” that the pigs were infected by a human, SENASA Director Jorge Amaya said in a television interview, since no pigs had been introduced to the farm for at least 60 days. The number of reported human cases in Argentina is rising rapidly, and now stands at 1391, with 22 deaths.

 

The only previously known case of swine infection with the new A(H1N1) occurred at a farm in Alberta, Canada; how the pigs caught the virus is still unclear.
