The cases were traces back to children who attend Millicoma and Blossom Gulch schools.
Whooping cough is a contagious respiratory infection spread by droplets produced from a cough or sneeze, the department said. Early symptoms include a mild cold with an occasional cough and then progresses to severe coughing fits and sometimes vomiting.
The health department advises parents of Millicoma students 10 years and older to make sure their children are up-to-date on their Pertussis booster shot, also known as the Tdap. The department also recommends Blossom Gulch students become up-to-date with their vaccinations.
The health department offers the Tdap vaccination at a reduced cost. Call 541-751-2419 for more information.
