Two possible cases of swine flu in Allegheny County have returned negative. However, County Executive Dan Onorato says there is a possibility that could change. Dr. Bruce Dixon says it is such a huge concern because there are variables with the swine flu, like how contagious it is and how fast it can spread. However, Dr. Dixon says it's best to be careful and use common sense rather than go overboard. He says the outbreak of the swine flu in 1976 ended in more deaths from the vaccine than the flu itself.
Next flu season is completely unpredictable, Dr. Dixon says. The swine flu could possibly stay at bay through the summer and then return in the winter months, but there is no way know for sure.
