(CNN) As an Indiana school district welcomed students to the 2020-21 academic year, one of their students tested positive for Covid-19 on the first day of class, according to a letter sent to parents.
The Hancock County Health Department notified Greenfield-Central Junior High School Thursday afternoon that one of their students, who had attended part of the school day, tested positive for Covid-19, Superintendent Harold Olin said in a letter.
Olin said the school enacted its "Positive COVID-19 Test Protocol" once school officials became aware of the positive result.
School officials immediately isolated the student within the school's clinic, and they examined the student's schedule, including transportation and extracurricular activities, to determine who had come in close contact.
As part of the district's return to in-person learning, "all areas of all schools" are already being disinfected professionally each evening, according to Olin's letter. But the superintendent noted that special attention would be given to areas and classrooms that the infected student had visited.
"We understand that this information will cause concern for some of you. It was very evident today that nearly all of our families and students were prepared to properly follow the safety protocols we have established," Olin said. "Adhering to these protocols is essential for maintaining a safe environment for all students and staff."
