The high-risk groups for AIDS are homosexual and bisexual males, intravenous drug users, and hemophiliacs. A recent study of 80 percent of the national inmate population revealed that only 750 out of 800,000 inmates have AIDS. Most cases result from drug abuse rather than sexual contact. No transmission was found among inmates or guards. Thus, risks on the job are low. AIDS is known to be transmitted through semen and blood, but it is not transmitted through casual contact. To protect themselves during searches and shakedowns, guards should avoid sharp objects. They should also avoid being cut or scratched during emergencies and should use gloves if in contact with blood. Washing after contact with others and cleaning and disinfecting surfaces on which body fluids have spilled are also important. They also need to respect the rights of infected individuals and avoid discrimination and intimidation. Details on other precautions to avoid infection, diagrams and illustrations showing the stages of the disease and biological processes involved. A leader's manual gives lesson plans and instructions for using the film and a companion film (see NCJ 104047) for inmates.
