Chronic Punishment: The unmet health needs of people in state prisons
This report offers the most recent national data on the health of people in U.S. state prisons, showing that prisons are continuing to ignore the plight of people in their care. People in prison suffer from several chronic illnesses and infectious diseases at disproportionate rates — such as hepatitis C, HIV, and mental illness — and prisons are failing to get many people the treatment they need. 50% of incarcerated people also lacked health insurance before prison, underscoring the reality that our criminal justice system punishes poverty.
