Measles Outbreak in Florida: Cases Rise in Collier County, Ave Maria University Monitoring Situation
As of February 20, 2026, Florida is experiencing a measles outbreak, with a notable concentration of cases in Collier County, particularly around Ave Maria University. Health officials are closely monitoring the situation and emphasizing the importance of vaccination.
Current Case Numbers
The Florida Department of Health (DOH) reports 66 confirmed cases of measles statewide as of February 7, 2026, with 46 of those cases located in Collier County. This figure differs from reports initially provided by Ave Maria University, which had identified 50 treated students and seven additional students in quarantine as of February 13, 2026.
Ave Maria University Response
Ave Maria University, a private Catholic university near Naples with approximately 1,300 students, initially tracked and reported its own case numbers. Although, the university has now shifted to referencing the state DOH dashboard for official updates. According to the university, the vast majority of its community is vaccinated, with approximately 98% protection against measles for those with a history of infection or who have received the full MMR immunization series, as per the Florida DOH.
Contagious Period and Quarantine
The DOH defines the contagious period for measles as including the four days before a rash appears and the four days after the rash begins. All students assessed by the university’s nursing staff and found to be within this contagious period are currently in quarantine.
Broader Florida Outbreak
Beyond Collier County, there is at least one confirmed case of measles in Lee County. The University of Florida in Gainesville also reported investigating exposures in two classrooms, with two confirmed cases in Alachua County reported by the state as of February 7, 2026.
Expert Perspectives on Outbreak Trajectory
Medical professionals offer differing opinions on the future course of the outbreak. Anthony Musingo, lead clinician at Ave Maria South Health clinic, suggests a second wave of cases is likely, stating, “Measles always has a second wave so more is likely to come.” However, Dr. Raul Enad with Cadenza Medical believes the outbreak may have already peaked in the university community and anticipates it will subside.
Resources and Prevention
The Florida Department of Health is providing resources to monitor for suspected measles cases and minimize further transmission, including offering free vaccination clinics. Individuals with concerns about exposure or seeking preventive measures are encouraged to contact DOH-Collier or their healthcare provider.
