Wisconsin Reports First Measles Death Since 1990

Health officials in Wisconsin confirmed that an infant died of measles, the state’s first measles-related death since 1990. The death occurred as part of a broader increase in measles cases across the United States, where three measles-related deaths have been reported within the same week. Pennsylvania also reported a measles-associated death, bringing the national total for the year to eight. All individuals who died were unvaccinated, with some ineligible due to age or health conditions. The measles vaccine is typically administered around a child’s first birthday. In Wisconsin, health officials noted that some transmission chains began with residents traveling out of state to attend events such as funerals and weddings. The U.S. has not recorded a measles death in more than 30 years in most states before the current outbreaks. Health departments continue to monitor the situation and update counts as additional information becomes available and relevant reviews are completed.

The measles vaccine is typically administered around a child’s first birthday, but health officials emphasize that some individuals are ineligible due to age or underlying health conditions. In Wisconsin, investigators traced some transmission chains to residents who traveled out of state for events such as funerals and weddings. Nationally, the current outbreak has resulted in eight measles-associated deaths, the highest toll since 1991. Health departments continue to update case counts as additional information becomes available and relevant reviews are completed. The virus remains highly contagious, and public health authorities stress that vaccination is the most effective way to prevent severe outcomes and further spread within communities.
