Biden rolled out 15 orders and two other action points at the Resolute Desk of the Oval Office.
Biden made the wearing of masks obligatory in all federal buildings and during interstate travel.
“It’s requiring, as I said all along, where I have authority, mandating masks be worn, social distancing be kept on federal property,” he told reporters.
He also signed orders for America to formally rejoin the World Health Organisation (WHO) and the Paris climate agreement.
