Public Health Sauk County confirmed 10 measles cases Friday, all in county residents who were unvaccinated and linked to another confirmed case elsewhere in Wisconsin.
Known exposures were limited to private gatherings, with no public exposure sites identified as of Friday morning, while county officials continue tracing contacts and notifying anyone exposed.
Symptoms typically appear 10 to 12 days after exposure and can include fever above 104°F, cough, red watery eyes and a rash; officials told people with symptoms to stay home and call a provider first.
The county update came less than 24 hours after Wisconsin reported an infant measles death—the state's first since 1990—as confirmed cases statewide had already passed 400 earlier this week.
