There is actually. Many of us have heard about it (who have employees and family members in Hong Kong and China). They are stopping shipments and it is a big fuss (they evacuated co-workers of mine). Local US news never covers these things- international news is all over it. But I was in asia during the SARS outbreak...I don't think there would be any issues with importing like that we would have heard about it by now surly. Now if you live in or around China that might be different but if there was any issues with imported items we would be hearing about it.
I did see something about the US possibly stopping all flights from China in a video or something the other day though.
