Two inmates of the prison at Alhaurín de la Torre near Malaga have tested positive for Covid-19 and a member of the medical staff has also been confirmed to have the virus.
Prisoners on two wings are now being isolated after prison managers activated virus containment protocols this Thursday.
Authorities have confirmed to SUR that the two prisoners tested positive on Wednesday, the day on which their preventative isolation ended after returning to the prison from leave.
Two wings, each with more than 130 inmates in them, have been isolated. Tighter virus containment protocols - which allow for the total confinement of prisoners in their cells - are available although this has not been deemed necessary yet.
