The whooping cough outbreak in Barrington appears to be over.

A RI Department of Health spokesman said that the number of cases peaked at 28 about two weeks ago, according to a story on eastbayri.com. More than two dozen of those cases involved students in the Barrington schools. There has not been a reported case since then.

Peter Hanney, the public information officer for the Department of Health, credits the clinic held at Barrington High School over two days for halting the spread of whooping cough, also known as pertussis.

Patricia Raymond, an RN who manages the immunization program for the health department, said at the clinic, though, that no vaccination is 100 percent effective. The town's "community immunity" level was raised, Raymond said, even though she expected new cases of pertussis to spring up.

On the final day of the clinic, there were 16 confirmed cases. A dozen more showed up as anticipated by Raymond over the next two weeks.
