I hope it doesn't get to that point. Please don't think selfishly in terms of your own desires about sales fares to Asia. As somebody who lived through SARS in Beijing in 2003 and was working for a (US) small business at the time, I can tell you that we had no human casualties, but the terrible effect on business for those few months, put us on a downslope that eventually led to the company's demise (and loss of jobs). And even that pales in significance to the sickness and loss of life among those directly affected by the illness....many of whom were health care workers themselves.
Red herring. Check history. As long as southern China remains a crowded hotbed of filthy animal husbandry, slaughtering, food sales practices, and lousy human hygiene, it's going to remain ground zero for many of the world's evolving strains of terrible flus. They don't need an artificial lab to wreak havoc.
