OTSEGO (WKZO) -- Classes at Otsego Baptist Academy resumed Monday morning after officials said that around 28-percent of its 43 students in Kindergarten through seventh grade came down with what was described as a "stomach bug."  The school was closed on Friday.

Allegan County Health Department staffers haven’t yet determined if a norovirus outbreak is behind the rash of illnesses.  The building was given a thorough cleaning over the weekend.
