Wisconsin health officials reported the death of an infant from measles on November 5, 2026, marking the state's first death from the virus since 1990. The Wisconsin Department of Health Services confirmed that a coroner listed measles as the immediate cause of death for the infant, who resided in southwestern Wisconsin. This incident is part of a larger trend, with at least eight measles-related deaths reported by states across the U.S. in 2026, including six in Pennsylvania and one in New York.
