What to know

  • Wisconsin's measles outbreak has expanded to Marathon County as of September 15, with a case linked to out-of-state travel, signaling geographic spread beyond the initial cluster.
  • The state has 164 confirmed measles cases, with Lafayette County—where vaccination coverage among toddlers is only 60%—serving as the outbreak's largest cluster.
  • The outbreak represents Wisconsin's largest in recent years, driven partly by lower-than-optimal MMR vaccination rates in affected counties.
