50 years ago, it was discovered that the United States Public Health Service and the CDC–the federal government–had left nearly 400 Black men with syphilis untreated for 30 years to study the long term consequences of the disease. They told these men that they were providing them free healthcare. The consequences of this inhumane, disgusting study still echoes among Black Americans today–leaving many deeply mistrustful of the healthcare institutions that are supposed to provide treatment. Worse still, the same attitudes about Black people continue to shape medical and public health interactions. Abdul sits down with Dr. Rueben C. Warren, Director of the National Center for Bioethics in Research and Healthcare at Tuskegee University and former Associate Director of Minority Health at the CDC, to talk about the history of the study and its lasting implications for health inequities.
