COLUMBUS — State health officials say Ohio whooping cough cases are up more than 40 percent this year, mirroring a trend seen elsewhere.
State Health Department spokeswoman Jen House told The Columbus Dispatch that 1,345 cases had been reported statewide by the end of October, about 400 more than during the first 10 months of 2009.
More than half of this year’s infections have been in Franklin County, which includes Columbus. The city’s health commissioner is encouraging residents to be vaccinated.
House says central Ohio’s Union County and Northwest Ohio’s Allen and Henry counties also are seeing relatively high caseloads.
Whooping cough tends to run in cycles. California is now seeing twice as many cases as in the last peak year, 2005.
