ST. JOSEPH -- Parents with kids in the Kennedy school in St. Joseph have been warned about an outbreak of whooping cough.

Elisabeth Lodge Rogers is the Executive Director of Student Services and Special Education for District 742.  She says there have been three confirmed cases, and another suspected case.

She says they contacted the Minnesota Department of Health, which directed them to send a letter home with students.

Whooping cough can be highly contagious.  Lodge Rogers says they also had a couple of isolated cases in other schools in the district earlier this school year.
