Prisons are the places where human rights are at risk. Since 1989, the European Committee for the Prevention of Torture (CPT) visits all 47 member states of the Council of Europe on a regular basis. The work aims the prevention of ill treatment and aims generally to improve the conditions of detention. Health care plays an important role either for the identification and reporting of ill treatment but generally also in regards to public health as almost all prisoners come back to the society and represent a vulnerable, underserved population which is highly affected by illness.
