The Prison Service has reduced the number of prison visits and the length of time visitors can see inmates as part of its response to the coronavirus.
Children are now prohibited from visiting the prisons and each inmate is only allowed one visitor a week for 15 minutes. Previously it was two half hour visits a week with up to three adults and no limits on children.
A number of prisoners, including 12 in the Dóchas Centre, are now in isolation but so far no case of Covid-19 has been identified in any of the country's jails.
Overall, 236 inmates have been granted temporary release because of the outbreak bringing the total on temporary release to 579.
