There’s an outbreak of whooping cough in Iqaluit and Pond Inlet, Nunavut, according to the territory’s chief public health officer.

The Department of Health announced the outbreaks in a pair of news releases Saturday. It said anyone can get the respiratory disease — also known as pertussis — but that the most severe cases are in children under the age of one.

Though it spreads easily from person to person, the department says it’s preventable by getting vaccinated.
