Whooping cough cases continue to rise in Michigan, and have now been identified in Berrien County.

There have been three lab-confirmed cases in the county, according to Health department epidemiologist Sara Palmer. She told WSJM this week that the cases have been reported since September, but the actual number is higher and above the average for the last five to six years.

Whooping cough introduces as a normal cold, but after two weeks it gets worse instead of better and can lead to violent coughing fits, nausea, and difficulty breathing. The disease is especially severe in children, infants, and people with underlying health conditions. The best way to avoid infection is to get vaccinated and stay home if you’re not well.
