Cascade County has confirmed its first case of pertussis, also known as whooping cough, in 2026. While only one case has been confirmed, the Cascade City-County Health Department says there are "multiple other suspected" pertussis infections that have not yet been confirmed through laboratory testing.
Why it matters
Pertussis is a highly contagious respiratory infection that can be especially dangerous for infants, pregnant women, and those with weakened immune systems. Prompt identification and treatment of cases, as well as ensuring proper vaccination, are crucial to containing the spread of this illness.
The details
Pertussis symptoms typically appear 7-10 days after infection and include malaise, mild fever, runny nose, and a cough that can develop into a high-pitched "whoop." The disease can lead to complications like pneumonia and seizures. Anyone experiencing these symptoms should seek testing and care, and those in close contact with infected individuals should also wear masks and get tested.
