Health officials in Marin County are putting parent's on alert as cases of whooping cough are up over the past two months.

During April and May, 36 cases of pertussis were reported in Marin County. That compares to five cases for the same time last year.

Most of the recent cases have been among school-age children, but infants are at the greatest risk for severe complications.

No hospitalizations or deaths have been reported.
