Scientists are monitoring the H5N1 bird flu virus for potential human-to-human transmission, specifically the risk of the virus trading genetic material with the H1N1 seasonal flu. Canada has already purchased 500,000 doses of a human bird flu vaccine for high-risk workers. In the U.S., local authorities in New Jersey have used police tape to block off parks where dead geese tested positive for the virus, a move critics label as "terrorism" through fear.
