HIV/AIDS in Prison, 2005
"In each year since 1991, the rate of confirmed AIDS has been higher among prison inmates than in the U.S. general population, but the gap has been narrowing. At yearend 2005, the estimated rate of confirmed AIDS in State and Federal prisons was more than 21?2 times higher than in the general population (table 3). In 1999 it was nearly 5 times higher.
"The shrinking difference between the rate of confirmed AIDS cases in prisons and the general population between 1999 and 2005 resulted from a decrease in the number of confirmed AIDS cases in prisons (down 20%) and an increase in cases (up 44%) among the general population."
