A new study shows the rate of HIV diagnosis in the US has reduced by a third in the past 10 years.
The survey was published today, 19 July, by the Journal of the American Medical Association.
The investigation is part of the publication's HIV research report, made public ahead of the start of the International AIDS Conference (held in Melbourne, Australia).
According to the Associated Press, the research showed '16 out of every 100,000 people ages 13 and older were newly diagnosed with HIV in 2011, a steady decline from 24 out of 100,000 people in 2002.'
One of the report's authors, Amy Lansky of the Centers for Disease Control and Prevention, told the Associated Press the information used spans more than a decade, making this a larger and longer look at HIV trends than any previous work.
Drops were seen in men, women, whites, blacks, Hispanics, heterosexuals, injection drug users, and most age groups.
The analysis did show a troubling trend of an increase in HIV diagnosis among gay and bisexual men.
There were no clear reasons for the decline. It could mean there are lesser infections happening, or those infected have been diagnosed.
