Health Guidance for the Public
Health officials have provided guidance for individuals who may have been exposed:
- Unvaccinated Individuals: Those who have never received a measles-containing vaccine should contact their healthcare provider immediately. Vaccination or immune globulin can be administered shortly after exposure to prevent measles.
- Vaccinated Individuals: Those who have received two doses of the measles, mumps, and rubella (MMR) vaccine or were born before 1957 are considered protected. Individuals who received only one dose are advised to consult their healthcare provider about obtaining a second dose for complete immunity.
Symptoms of measles typically appear 7 to 14 days after exposure and include fever, cough, runny nose, red eyes, and a rash that begins on the face. The virus is highly contagious and can remain airborne for up to two hours after an infected person has left a location.
Official Statements & Responses
Dr. Sarah Kemble, state epidemiologist, emphasized the importance of vaccination, stating, “It is rare for people to get measles if they’ve had the vaccine because the vaccine works very well. However, some people can still get breakthrough measles, as is in the case with this individual who was fully vaccinated.” The DOH is actively contacting individuals who may have had close contact with the visitor and has issued notifications to relevant airlines and airports.
Criticism & Opposition
While the DOH has taken steps to alert the public, some critics argue that the response may not be sufficient given the rising number of measles cases nationally, with over 1,100 confirmed cases reported in the U.S. as of late February 2026. This situation underscores the need for ongoing public health education regarding vaccination.
What's Next
The DOH continues to monitor the situation and is urging anyone who believes they may have been exposed to contact their healthcare provider or the DOH Disease Reporting Line for further guidance.
