Wisconsin health officials had confirmed 267 measles cases in 2026 as of Oct. 13, with local spread in four southwestern counties. Officials say the MMR vaccine is the best protection.
The Wisconsin Department of Health Services (DHS) said that, as of Oct. 13, it had confirmed 267 measles cases in the state in 2026. Officials say the disease is still spreading locally and that cases keep appearing in several counties.
According to DHS, the outbreak in Grant, Iowa, Lafayette and Vernon counties includes 237 confirmed cases and six probable cases. Elsewhere in the state, the department reported five probable cases in Rock County, six confirmed cases in Marathon County and 11 confirmed cases in Chippewa County.
DHS describes measles as a highly contagious disease caused by a virus. It can spread through the air and through direct contact with infected people. Symptoms typically begin 10 to 21 days after exposure. Complications can include pneumonia, brain damage and deafness, and the disease can sometimes be fatal.
Officials say vaccination with the measles, mumps and rubella (MMR) vaccine is the best way to prevent infection. Two doses are about 97% effective, and one dose is about 93% effective. People most at risk are those who are unvaccinated or do not know their vaccination status. That includes unvaccinated young children and other adults who are not immune.
A related broadcast report said health officials in Pennsylvania are reporting four measles-related deaths since last month. It also said Wisconsin officials had confirmed two lab-tested cases in Vernon County while investigators trace potential connections.
