A prison officer in Cork Prison is one of two officers in the prison system who have been diagnosed with Covid-19.
Both are currently off work.
It is understood that up to a dozen colleagues in Cork Prison are in self-isolation following the diagnosis.
The officer is doing well, according to prison sources.
Efforts are being made throughout the prison system to free up space to allow for the isolation of inmates in case of an outbreak among the prison population.
This morning, there are 112 inmates on temporary release from Cork Prison. There are 266 in the prison itself, which has a capacity for 296 inmates.
A spokesman for the Irish Prison Service said: “Like all organisations across the civil and public service, the Irish Prison Service currently has a number of staff on leave owing to the need to self-isolate. The Prison Service at all times ensures that up to date public health advice is followed by all of our staff, ensuring the need to self-isolate where appropriate, and on foot of medical/public health advice.
“The Irish Prison Service is an organisation of almost 3,500 employees. Accordingly, it can only be expected that out of a staffing cohort of that size, there will be a certain number of staff who have been advised to self-isolate at any given time. However, the vast majority of staff continue to report for duty as normal.”
