We developed predictions of HIV/AIDS caseloads and costs for the North
ern Virginia Planning District Commission as input to its continuing e
valuation of the economic welfare of northern Virginia's cities and co
unties. We developed a series of procedures beginning with US case and
cost estimates for the period 1990 to 2000 and leading to estimates o
f state and local HIV/AIDS cases and costs. As a result, we estimate t
hat the annual incidence of AIDS in northern Virginia will increase fr
om 391 in 1990 to 643 by 2000, while pre-AIDS prevalence will decline
from a peak of about 6,900 in 1993 to about 4,400 in 2000. We estimate
the medical costs to the region of AIDS (excluding pre-AIDS cases) wi
ll reach $65 million annually (1992 $) by the turn of the century.
