The number of parents opting out of having their kids vaccinated against whooping cough, also known as pertussis, is on the rise, according to a recent report. This is resulting in an increase in whooping cough cases statewide.
In 2012, New York state saw the highest number of whooping cough cases in decades, with more than 3,000 cases confirmed statewide.
The Centers for Disease Control is encouraging everyone to make sure they are vaccinated against pertussis -- commonly known as whooping cough. The CDC says New Yorkers in particular need to be protected against the disease.
