In August 2008, CDC published the first
national HIV incidence (new infections)
estimates using new technology and
methodology that more directly measure the
number of new HIV infections in the United
States. The first analyses, published in the
August 6, 2008 issue of the Journal of the
American Medical Association (JAMA), showed that in
2006, an estimated 56,300 new HIV infections
occurred - a number that is substantially
higher than the previous estimate of 40,000
annual new infections.
It should be noted that the new incidence
estimate does not represent an actual
increase in the numbers of HIV infections,
but reflects a more accurate way of
measuring new infections. A separate CDC
historical trend analysis published as part
of this first analysis suggests that the
annual number of new infections was never as
low as 40,000 and that it has been roughly
stable since the late 1990s.
The analyses published in the JAMA article
are the first of many that will be published
using data from this new system.
