ASTORIA - As a result of several recent cases of pertussis locally, the Clatsop County Public Health Department is encouraging everyone in the county ages 2 months and above to be vaccinated against the illness, also known as whooping cough.

The department is reporting a total of six positive reports of pertussis – a 2-year-old child, four school-age children and a 31-year-old adult. On Tuesday the health department sent out a memo to parents of schoolchildren describing the disease’s symptoms and means of spreading, and tips for prevention and treatment.
