North West Anglia NHS Foundation Trust confirmed that 533 patients have been successfully treated across Peterborough, Hinchingbrooke and Stamford Hospitals.
Patients were given the green light to continue their recovery process from their own home instead of the hospital.
The trust wrote: "Thank you to all of our amazing staff for your ongoing commitment, dedication and bravery in helping to fight this pandemic. You are our heroes."
They added: "We are continuing to see and treat patients with Covid-19 and we send our thoughts and prayers to all those who have lost their lives to the virus."
Changes have started to be implemented across the hospital, with outpatient appointments resuming and visiting policies being reviewed.
