HIV seroprevalence and the acceptance of voluntary HIV testing among newly incarcerated male prison inmates in Wisconsin.

In 1986-88, voluntary and blinded HIV testing was conducted among Wisconsin male prison entrants. The HIV seroprevalence was 0.30 percent in 1986, 0.53 percent in 1987, and 0.56 percent in 1988. The seroprevalence rates among entrants tested voluntarily did not differ from those tested blindly. Voluntary HIV testing was accepted by 71 percent of male prison entrants in 1988; among entrants reporting intravenous drug use 83 percent consented to voluntary HIV testing. Voluntary HIV testing of entrants appears to be an effective screening strategy in Wisconsin prisons.
