-8D. Immediate observations under Article 8, paragraph 5, of the Convention 11. During the end-of-visit talks with the Greek authorities, on 1 December 2021, the CPT’s delegation made three immediate observations under Article 8, paragraph 5, of the Convention. The Greek authorities were requested to ensure that: - at Kos Prison, persons who are tested positive for the SARS-CoV-2 virus are held separately from other prisoners to reduce the risk of transmission and subsequent illness. More generally, overcrowded and unhygienic dormitory-style accommodation is not conducive to reducing the risk of infection. - at Corfu Prison, the three cells in K Wing used for disciplinary/protection purposes be taken out of service immediately. Further, the remaining cells in K Wing should, within one month, be either completely renovated or permanently taken out of use. The transgender women held on K Wing should also be moved to alternative accommodation within one month. - at Korydallos Special Health Centre for Prisoners, the patient HH be provided with new prostheses for his arms and that, in the meantime, he be offered the necessary around the clock care to provide for his needs. These observations were confirmed by letter of 6 December 2021 when transmitting the delegation’s preliminary observations to the Greek authorities. On 7 January 2022, the Greek authorities informed the CPT on the actions taken in response to these immediate observations and on other matters raised by the delegation at the end-of-visit talks. This response has been taken into account in the relevant sections of the present report.
