The measures will remain in place at Peterborough City, Hinchingbrooke and Stamford Hospitals, following any government guidance changes on that date.
Patients, visitors and staff will all still be required to wear a mask or visor, maintain the two-metre social distancing rule and utilise the hand sanitisation stations when entering or exiting each area of the hospital.
The measures are also in place to reduce footfall at the three hospitals, and Jo Bennis, chief nurse for North West Anglia NHS Foundation Trust, said: “While many areas across the country may be easing Covid restrictions, I would like to reiterate that this will not be the case within our hospitals.
“We ask that anyone visiting or working in our hospital sites will continue to wear a face mask, remain two metres apart, observe hand washing guidelines and sanitise their hands upon entering and exiting our buildings.
“I would like to thank everyone for adhering to our safety advice and doing their bit to continue to protect our patients and themselves. These measures really do make a difference to help minimise the spread of the virus.”
