Wisconsin measles outbreak reaches 431 cases; infant death reported, six cases in Marathon County

Wisconsin’s measles outbreak has claimed the life of an infant, marking the state’s first measles-related death of this kind since 1990. The Wisconsin Department of Health Services says the infant’s immediate cause of death was measles. Officials are withholding additional information to protect the family’s privacy.

As of November 3rd, Wisconsin had reported 431 measles cases across 13 counties—the highest number in the state in more than 35 years. Nine people have required hospitalization. Marathon County has reported six confirmed cases. To date, there have been no reported cases in Lincoln County or its neighboring counties across the Northwoods.

Health officials say measles can cause serious complications, particularly for children under five, pregnant women and those with weakened immune systems. The MMR vaccine remains the best protection against the disease. Two doses are approximately 97 percent effective at preventing measles.

Anyone who develops a fever and rash, especially after possible exposure, should contact their healthcare provider by phone before visiting a clinic or hospital.
