This paper analyzes the impact that the Covid-19 pandemic has had on corrections and crime in the southern region of Europe formed by Spain and Portugal. The main mechanisms of transmission of Covid-19 are the physical proximity between people and the fact of sharing eventually infected targets. In prisons and other correctional contexts people live in close proximity and share the same facilities. As a result, the correctional context has proven to be a critical "hot spot" for the transmission of the Covid-19 pandemic in inmates and correctional staff. First, the magnitude of the infection and their associated health and psychosocial problems (prison incidents, social isolation.. .) are described. Second, the main sanitary, social, and correctional measures applied to prevent contagion and their related damages are presented (lockdown, use of communication technologies with families, etc.). Third, it is analyzed whether there has been a relationship between the confinement caused by the pandemic and the crime rates observed in Spain and Portugal during this same period. Finally, from the impact in corrections of pandemic and the actions taken to fight it, several important lessons are derived for the future improvement of correctional systems.
