PORTLAND, Maine — Maine health officials say the state had nearly four times more cases of whooping cough last year than in 2010.
State epidemiologist Stephen Sears says 204 cases of the disease, also known as pertussis, were reported last year. That’s up from the 53 cases a year earlier.
Sears tells Maine Public Broadcasting Network that whooping cough is a cyclical disease and that cases tend to go up every three to five years.
He says many of the cases were concentrated in the period from September through November and that activity has since died down.
