New HIV cases between 2006 and 2009 remained relatively stable at about 50,000 per year, according to a Centers for Disease Control and Prevention (CDC) statement. These new data come from the CDC's first multiyear estimate from its national HIV incidence surveillance. New HIV cases among young black men who have sex with men (MSM) increased by 48 percent—from 4,400 cases in 2006 to 6,500 cases in 2009. All racial and ethnic groups of MSM and black women faced the highest HIV rates. The CDC also revised its 2006 estimate of new HIV cases down to 48,000, which previously had been 56,300. The data will be published in the scientific journal PLoS ONE.
