Wisconsin remained free of swine flu Monday, but the state health officer said he wouldnâ??t be surprised if cases hit here.
“Itâ??s possible the outbreak could grow to affect many people in this state,” said Dr. Seth Foldy of the state Department of Health Services.
A Mexico-based outbreak of the disease, which erupted last week, has expanded to five U.S states and other countries, with school closures in New York and other states.
