The U.S. Centers for Disease Control and Prevention recently estimated that 47,500 Americans were newly infected with HIV in 2010.
In the newly released CDC report, entitled "Estimated HIV incidence among adults and adolescents in the United States, 2007-2010," the agency says that HIV remains a serious public health problem.
Since 2007, the HIV incidence rate has remained fairly stable at approximately 50,000 new infections per year. According to the report, African Americans, Latinos, and gay and bisexual men of all ethnicities continue to be infected at a rate disproportionate to their overall numbers.
The analysis also found two noteworthy trends. There are early signs of a decrease in HIV infections among black women and a troubling and continued increase in infections of young gay and bisexual men.
Homosexual men continue to remain the population most affected by HIV. Although estimates place the number of homosexual men at four percent of the U.S. male population, they accounted for more than 75 percent of new HIV cases in 2010.
Heterosexuals accounted for nearly 25 percent of new HIV cases in 2010. Women accounted for approximately 66 percent of new HIV cases among heterosexuals, although that portion has decreased since 2007.
