OTSEGO, MI (WHTC) - Otsego Baptist Academy will not hold classes today 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.” Allegan County Health Department staffers haven’t yet determined if a norovirus outbreak is behind the rash of illnesses. The building will get a thorough cleaning through the weekend before classes resume on Monday.
