The Council of Europe, EuroPris and other international organizations have also expressed their position on the principles of treatment of people convicted to deprivation of freedom concerning the COVID pandemic, as well as the rules for operation of prisons. The Hungarian Prison Service has acted quickly, efficiently and effectively when the epidemic broke out. As a result of the successful protection, no serious virus outbreaks or mass illnesses happened.
