Wards at West Suffolk Hospital which were struck by the highly contagious norovirus are due to fully reopen by tomorrow.
Wards G3 and G8 at the Bury St Edmunds hospital are being cleaned after bays were affected by the sickness bug.
Ward G5 also reopened earlier this week.
Patients first showed symptoms of norovirus about two weeks ago.
Hospital bosses have urged anyone showing symptoms to stay away from the hospital for at least 72 hours.
