The HSE has announced new arrangements to protect older people and those with disabilities.
The arrangements relate to closures of all day services and day hospitals, and the visiting of older people in nursing units and homes.
The HSE has announced the closure, with immediate effect, of all day services and day hospitals for both older persons and for disability services in Donegal, Sligo, Leitrim, Cavan and Monaghan.
The HSE says all service users and family members have been contacted and provided with a named contact person who will respond to any queries.
Daily contact will be made with people at risk by day service personnel.
Also, no visiting is allowed in older persons community hospitals or nursing units across the region.
People with queries should contact the nurse manager of such units.
There are also visiting restrictions in all community group homes and residential centres for persons with a disability. Again, the HSE says all service users and family members have been contacted.
John Hayes, chief officer of the Community Health Organisation that covers Donegal, Sligo, Leitrim, Cavan and Monaghan, says the priority is to protect service users, residents, staff, those with disabilities and older persons who are vulnerable to infection.
