Vermont reports rise in whooping cough cases

State officials in Vermont say that nine cases of whooping cough have been confirmed, with five of the cases found in the past two weeks alone.

Vermont has become the latest in a series of states that has become concerned about pertussis, also known as whooping cough, according to, leading the Vermont Department of Public Health has issued an alert to health care providers about the rising number of pertussis cases in the state.

Vermont Health Commissioner Wendy Davis told that, while pertussis is common during this time of year, it needs to be taken seriously, especially by parents of school aged children.

"The number of cases of pertussis is not unusually high for this time of year, but it is a good reminder for parents, providers and school health officials to make sure children are fully vaccinated, and to look for symptoms of the disease," Davis said to "Teenagers and adults should also check their records, since they are a frequent source of exposure to infection for infants and young children."

Vermont state law requires that all students be administered at least four doses of a pertussis-containing vaccine. If a pertussis case is confirmed in school, letters are usually sent to inform the parents about the illness, to describe the symptoms and to urge parent to have children displaying symptoms seek medical care.
