Michigan agriculture and health officials announced that have identified ten pigs at the Jackson County Fair have tested positive for swine influenza, or swine flu.
The fair, that began on Aug. 4, ends today. All the pigs were removed and pig barns have been closed.
No human illness have been reported to date, but Jackson County health officials urge health providers to be on the lookout for patients with respiratory symptoms who may of had exposure to swine or attended the fair.
Swine flu viruses do not normally infect humans. However, sporadic human infections with influenza viruses that normally circulate in swine and not people have occurred.
Most commonly, human infections with variant viruses occur in people with exposure to infected pigs (e.g., children near pigs at a fair or workers in the swine industry).
Illness associated with variant virus infection has been mostly mild with symptoms similar to those of seasonal flu.
