St. Luke School will be closed Friday, apparently because so many students and staff have been sick this week.

“We’re looking at all our options and that is one we are considering,” Principal Leslie Vondrell said earlier Thursday. The school posted an announcement to whiotv.com about the closing.

On Thursday, 34 students and two teachers at the school, 1442 N. Fairfield Road, were out sick. The school has an enrollment of 424. Vondrell said the unusual number of absences “have been pretty continuous throughout the week.”

Illness forced the closing of Mother Brunner Catholic School in Trotwood on Thursday after as many as 50 students were out sick the day before. Five teachers also did not report to classes because of illness.

The school on Denlinger Road, with an enrollment of 335, will remain closed Friday as part of a previously scheduled closure, school officials said.

Jenny Birtle, spokeswoman for Mad River Local Schools, said that attendance has been normal this week with a 91 or 92 percent rate at all its schools.

The previous two weeks, though, Birtle said the district was “hit pretty hard” with students dealing with abdominal issues and headaches. There were 30 to 65 students absent in some buildings during that stretch, “but nothing where we had to close a building down,” she said.

Sue Gunnell, Huber Heights City Schools superintendent, said the district is not experiencing an increase in absence rates at its buildings.
