Children's Hospital of Wisconsin is banning young visitors and at least one Milwaukee school is closing due to the flu outbreak that has ravaged the country.

The suburban Milwaukee hospital is not allowing children under 12 to visit patients beginning Thursday to prevent the flu from spreading. That doesn't include clinic appointments.

Mother of Good Counsel School in Milwaukee says it will be closed for the remainder of the week due to an increasing number of sick students and staff. School officials say 30 percent of students were absent on Tuesday.
