Twelve scientific teams in more than a dozen states will receive National Institutes of Health grants to study effective ways to prevent and treat HIV/AIDS among people in the criminal justice system. The grants, announced today, will be awarded primarily by the National Institute on Drug Abuse (NIDA), with additional support from the National Institute of Mental Health (NIMH) and the National Institute of Allergy and Infectious Diseases (NIAID), all components of NIH. The research will take place over a five-year period.
