Covid news live: WHO declares 2022 to be the year ‘we end the pandemic’ as US

On Monday morning, a mid-level staff member, who does not regularly have contact with the President, received a positive result for a Covid-19 test.

Three days earlier, on Friday, that staff member had spent approximately 30 minutes in proximity to the President on Air Force One, on the way from Orangeburg, South Carolina to Philadelphia, Pennsylvania.

This staff member is fully vaccinated and boosted, and tested negative prior to boarding Air Force One, as is required for everyone traveling with the President.

This staff member did not begin to experience symptoms until Sunday, and was tested on Monday.”
