Rockland officials say there are now 12 cases of whooping cough in the county.      

News 12 is told that nine kids are under the age of five, and the rest are between five and 10-years-old.

Only one of the children has a record of being vaccinated.

County health officials do not consider this a "pertussis – outbreak," saying there are no links between the different households.

Symptoms of pertussis include fever, runny nose and a violent cough.
