This report points out the impediments to AIDS prevention efforts currently being encountered by the Centers for Disase Control's Center for Prevention Services (CPS), which works through cooperative agreements with state and local health departments. As a result of the alarming growth of the HIV (human immunodeficiency virus) epidemic, funding for programs targeted to persons at increased risk almost doubled annually between 1985 and 1989, while the responsibilities of the CPS were also greatly enlarged. A review of the objectives, scope, and methodology of the CPS is presented, and difficulties in meeting staffing targets are discussed. It is noted that the growing need for staff with highly specalized skills, compounded by various funding problems, have resulted in staffing shortages that have hindered key technical assistance and monitoring activities in the CPS. A chart, accompanied by narrative clarification, presents information on the flow of AIDS funds from the Center for Disease Control to state and local health agencies. (JD)
