1 The HIV/AIDS data through 10/31/2004 show substantially fewer reported AIDS cases than in previous months. This is because
Washington and King County completed a national AIDS case de-duplication project in October. AIDS cases have always been
counted for the geographic area where they were first diagnosed with AIDS. If a PWA is reported as a new diagnosis in King
County but is known to have moved from another State, we confirm with that State where the AIDS diagnosis FIRST occurred.
However, if we are unaware of the prior residence, we have no routine way to confirm with another State and would count the case
as King County. This is how duplicates are created in the national data set. During the past year, we have participated in a national
project to identify duplicates. CDC (which does not have names) provided us with a list of potential matches to cases in other
States. We then consulted with each State to determine which were duplicates, and which State should appropriately count the
case. Nationally, about 5% of all cases were found to be duplicated in more than one State. We discovered that 405 Washington
State Cases (225 in King County) were previously diagnosed while residing in other States. Therefore, we have removed those
cases from our counts. All the data are accurate according to the revised tallies.
2 These cases were diagnosed with HIV infection between July 2001 and June 2004, and reported to Public Health–Seattle & King
County or the Washington Department of Health as of 11/30/2004.
3 United States HIV data are not currently available in a format consistent with the Washington data. In addition, U.S. AIDS data do
not include age distributions by year of diagnosis. The most current available national AIDS data are through December 2002.
TECHNICAL NOTE: The U.S. data do not show specific incidence estimates for hemophilia or transfusion cases for 2000–2002;
these numbers were interpolated from earlier incidence data.
