Two more cases of presumptive swine flu have been linked to the Minnesota State Fair. The Minnesota Department of Health says this is the first human infection of the H3n2v strain linked to the fair. The other cases involving the same strain were linked to a live animal market in Dakota County.

Wisconsin health officials report two cases of people infected with a new strain of swine flu. Both people are connected to the Wisconsin State Fair — a worker and a swine exhibitor, the Associated Press is reporting. This news comes on the heels of a report from a University of Minnesota scientist who found swine flu in a significant number of pigs at the Minnesota State Fair in 2009.

The health department reported two Twin Cities area children were the first Minnesotans confirmed to have contracted a new strain of the swine flu, just a few days before the Minnesota State Fair. But fair officials say the swine barn is safe and it will be open as usual this year.

Another case of a new strain of swine flu has has been linked to a live animal market in Dakota County. The second case involves a man in his twenties that recently purchased a pig from that market.

Opening day at the fair started off a little bumpy with a brief ride malfunction and lower attendance at the pig barn after the Swine Flu virus raised cause for concern. Day two kicks of with the Governor's Fire Prevention Day and Alan Jackson performs at the Grandstand tonight.

A University of Minnesota veterinarian, Dr. Jeff Bender, is releasing the results of his study and it comes with a warning for anyone planning to visit the Minnesota State Fair -- which starts one week from Thursday. Scientists found 19 percent of the 57 pigs tested at the Minnesota State Fair in 2009 had the H1N1 flu virus -- compared to none of the 47 samples the year before. Fair officials tell the Star Tribune they've stepped up precautions for both fairgoers and livestock.

The Minnesota Department of Heath says a fourth case of fungal meningitis has been identified in the state. The patient is a woman in her 70s. Two other Minnesota women, both in their forties, with the infection were released from the hospital last week and are being treated on an outpatient basis.
