City of Jacksonville confirms 5th measles case in Duval County in 2026

DUVAL COUNTY, Fla. – The City of Jacksonville confirmed a 5th measles case in Duval County in 2026.

Dr. Sunil Joshi, the Chief Health Officer of Jacksonville, gave recommendations for health care providers and facilities in light of this “outbreak.”

In light of this outbreak, we remind you that healthcare facilities should recommend that all healthcare personnel, regardless of birth year, who are unvaccinated and who lack laboratory evidence of measles immunity or laboratory confirmation of disease receive two doses of MMR vaccine at the appropriate interval.

During this outbreak, facilities are strongly encouraged to place signage outside emergency departments, urgent care facilities and clinic entrances advising patients with rash and febrile illness to remain outside and request initial medical evaluation prior to entering the facility. This measure can help reduce potential exposure within healthcare settings.

Patients concerned that they may have measles should obtain appropriate diagnostic testing at a local laboratory with a healthcare provider’s order.

At least two of the five cases involve pediatric patients from the same home and details have not been released on the other three.
