Symptoms of pertussis, also known as whooping cough, begin like a cold, with a runny nose, sneezing, a mild fever and a cough that slowly gets worse. The second stage includes uncontrolled coughing spells and a whooping noise when the person inhales.
Anyone who thinks they or their child may have pertussis should stay home and not attend school or work, and make arrangements to be seen by a health care provider, health district officials said.
Anyone who thinks they may have been exposed to someone with pertussis should call the health district at 766-7960 and speak to a public health nurse.
