Overview
- The county confirmed that a traveler infected with measles was infectious in Los Angeles County after arriving at Hollywood Burbank Airport on June 17 on Southwest Flight 4245 and passing through Gate A4.
- Officials identified specific exposure windows at Gate A4 on June 17 and at the Thrifty rental car location in Burbank on June 17 and June 18 and said they are working with the CDC and other local health departments to notify passengers who sat near the traveler.
- Local outlets report that people exposed on June 17 should monitor for symptoms through July 8 and those exposed on June 18 should monitor through July 9, and the county noted anyone who remains symptom-free after the 21-day period is no longer considered at risk.
- Los Angeles County Health Officer Dr. Muntu Davis urged residents to confirm MMR vaccination because two doses are about 97% effective and most U.S. cases this year have been in people who were unvaccinated or unsure of their status.
- Public health said the investigation is ongoing and warned that high summer travel and large events raise importation risks as the United States has reported more than 2,100 cases this year and Mexico is experiencing a large outbreak.
