About H1N1
2009 H1N1 viruses are not spread by food. You cannot get infected with H1N1 virus from eating pork or pork products. Eating properly handled and cooked pork products is safe.
Spread of H1N1 virus is thought to occur in the same way that seasonal flu does, Viruses are transmitted mainly through droplets（小滴）from coughing or sneezing of an infected person. Keeping a safe distance is recommended. Studies have also shown that flu virus can survive on object surfaces for 2 to 8 hours. Sometimes viruses can be spread when a person touches something like the surface of a desk that is polluted with droplets, and then touches his or her eyes, nose, or mouth before washing their hands.
The symptoms of H1N1 flu virus in people include fever, cough, sore throat, runny or stuffy nose and body aches. Severe illnesses and death have occurred as a result of illness associated with this virus.
