Overview
- The Louisiana Department of Health said an adult exposed during international travel was infectious at MSY on Nov. 9 from 5:00 to 8:30 p.m. in Concourse B and beyond the security checkpoint.
- The patient is isolating, was not hospitalized, and the individual's vaccination status is unknown.
- Officials will directly notify passengers who were on the same flight as the confirmed case.
- This is Louisiana’s third measles case of 2025, with the earlier two cases also linked to travel in the New Orleans region.
- Measles can remain airborne for up to two hours and infects about 90% of unvaccinated people exposed, so residents are advised to watch for symptoms for up to 21 days and alert providers before in‑person visits if exposed.
