A 2003 Centers
for Disease Control and Prevention initiative in which the
agency distributed nearly 800,000 rapid HIV antibody tests
to community groups and prisons helped bring in many
more people for testing than usual, a new report says.
The findings,
published Thursday in the CDC publication Morbidity and
Mortality Weekly Report, validate a widely
held assumption--that people are more apt to seek
testing if there is a quick and easy method, such as
OraSure's saliva test for HIV antibodies, the CDC
said. If the test results are available within a half
hour, people are more likely to wait for them than they are
to return for results a week or two later, as is
necessary for conventional blood tests. Studies show
nearly one third of people who undergo conventional
HIV testing never return for their results.
The CDC said that
at the end of 2003 about one quarter of the estimated 1
million HIV-positive Americans had not had their infections
diagnosed. That same year, the CDC began distributing
rapid tests to 230 organizations in 21 states and
Washington, D.C. Of the 372,960 tests administered,
1.2% (4,650) of them showed the patient to
be HIV-positive.
"The results
suggest that [the program] helped scale up rapid
HIV-testing programs in the United States and enabled
diagnosis of HIV in persons who might not have had
their infections diagnosed otherwise," the report
said.
"Although
follow-up client data were not collected on the 4,650
confirmed HIV-positive test results, previous research has
indicated that the majority of persons who learn they
are infected with HIV take steps to prevent
transmission to others and obtain health care that can
prolong the quality and duration of their lives," the
CDC said. (Reuters)
