Since the beginning of the pandemic, TSA has cumulatively had 10,392 federal employees test positive for COVID-19. Of those, 9,932 employees have recovered, and 28 have died after contracting the virus. More than 50,000 TSA officers work at the country's airports.
The TSA has extended a mask mandate for airports and planes until at least January 2022.
Under an executive order signed by President Joe Biden earlier this month, all federal workers are required to be vaccinated for COVID-19 by Nov. 22 unless they receive an exemption.
