A campground in Polk County becomes the center of a possible flu outbreak.

1,200 people from a middle Tennessee church group recently attended a camp at Horns Creek Cabins and Retreat in Ocoee.

The group reportedly cut its camp short after 15-young people came down with the fly.

A Goodlettsville doctor told the Associated Press the church members tested positive for Type-A influenza, a broad category of viruses that include swine flu.

The doctor had to quarantine part of her clinic after making the discovery.

Horns Creek remains open.
