Almost 1000 Pennsylvania state prisoners have HIV. About 75 of those infected are women. Of those infected, about 250 actually have AIDS. Except for so-called natural causes, AIDS kills more prisoners than all other causes combined. About 125 Pennsylvania prisoners have already died from the disease. These numbers are significant because some infected persons are intimately sharing double cells with other prisoners. All the infected prisoners have daily contact with non-medical prison staff. In addition to those in state prisons, about 950 prisoners in Pennsylvania's county jails have HIV including 220 in Philadelphia County. About 50 prisoners in county jails have already died from the disease. The great majority of those who are infected are blacks. While the disease was most frequently contacted through homosexual and sexual contacts, some cases are traced to intervenus drug use and even tattooing. All the 1900 infected prisoners are expected to die.
