A staff member and a student at Norwell High School have reported they have the pandemic H1N1 influenza, commonly called swine flu, Superintendent Scott Mills said.
The staff member and student said they were treated by a physician who made the diagnosis, Mills said.
Upon hearing the reports, Mills sent a letter to parents saying the H1N1 outbreak has so far resulted in a mild flu. He emphasized flu-prevention measures such as frequent hand-washing and covering your mouth when coughing or sneezing.
Students in the Northern Wells district returned to school Aug. 13, and Mills said he has seen no increases in reported absences because of illness.
As of Thursday, the Indiana State Department of Health has confirmed that 317 people in Indiana have contracted H1N1, and four have died this year.
The states 50 volunteer sites provide the Indiana Department of Health with weekly reports and swab samples for testing.
Officials believe more people have unconfirmed cases of H1N1 because that is the only flu strain circulating.
