Oakland County health officials say they’re seeing a spike in whooping cough (AKA pertussis), largely among kids in day care and preschool. That’s likely because the disease is contagious and spreads easily, but kids that age aren’t old enough to have had all their pertussis vaccinations yet.
Since November, the county health department says it's seen 56 confirmed cases of whooping cough, compared with 10 this time last year. The county saw just 59 cases for all of last year. None of those cases has been fatal.
