More than 40 measles cases have been documented at Ave Maria University in southwest Florida, making this the largest outbreak on a U.S. college campus in recent years.

As of February 7, 2026, the Florida Department of Health reported 46 confirmed measles cases in Collier County, with the university identified as the main location of the outbreak. The cluster has led to health and operational measures on campus to limit further spread.

University officials stated that all students assessed by nurses and identified as being within the four-day contagious period after rash onset are currently in quarantine. This step follows guidance from the Florida Department of Health regarding the management of contagious diseases.

Since the semester began, 48 students who were assessed by campus nurses have completed the contagious period and now possess natural immunity to measles. The university has continued to monitor the health status of affected students and update protocols as needed.

What the numbers show

  • 46 confirmed measles cases in Collier County as of February 7, 2026
  • More than 40 cases reported on the Ave Maria University campus
  • 48 students have progressed beyond the contagious period and gained natural immunity

The contagious period for measles, according to Florida Department of Health guidance, includes the four days before and four days after the appearance of a rash. This information has been used to determine quarantine timing and campus health protocols.

The university stated that the majority of its community is vaccinated, and individuals with either prior infection or full MMR immunization are about 98% protected from measles. This level of protection has influenced the university's approach to campus operations during the outbreak.

Campus activities, including in-person classes and religious services, continue to operate in accordance with Department of Health recommendations. The university has indicated that it will maintain these procedures while monitoring guidance from health authorities.
