About H1N1

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.
