Walensky, MD, MPH Director Centers for Disease Control and Prevention 1600 Clifton Road, NE Atlanta, GA 30333 Dear Dr. Walensky: We are writing on behalf of Delta Air Lines to the Centers for Disease Control and Prevention (CDC) to reconsider the current guideline for 10 days of isolation in fully vaccinated individuals who experience breakthrough COVID-19 infections. This guidance was developed in 2020 when the pandemic was in a different phase without effective vaccines and treatments. At Delta, over 90% of our workforce are fully vaccinated, and those rates are increasing daily. Our employees represent an essential workforce to enable Americans who need to travel domestically and internationally. With the rapid spread of the Omicron variant, the 10-day isolation for those who are fully vaccinated may significantly impact our workforce and operations. Alt text continued in thread

ALT archive.cdc.gov Media Statement For Immediate Release: Monday, December 27, 2021 Contact: Media Relations (404) 639-3286 Given what we currently know about COVID-19 and the Omicron variant, CDC is shortening the recommended time for isolation for the public. People with COVID-19 should isolate for 5 days and if they are asymptomatic or their symptoms are resolving (without fever for 24 hours), follow that by 5 days of wearing a mask when around others to minimize the risk of infecting people they encounter. The change is motivated by science demonstrating that the majority of SARS-CoV-2 transmission occurs early in the course of illness, generally in the 1-2 days prior to onset of symptoms and the 2-3 days after.
