ST. PAUL  — Minnesota health officials said the number of HIV diagnoses dropped slight in 2013.

The Minnesota Department of Health said Tuesday 301 cases were reported last year, compared to 314 in 2012. The department’s report says there are about 7,700 people living with HIV or AIDS in Minnesota.

The report shows most of the cases, 82 percent, are concentrated in the Twin Cities metro area. Nearly one in three HIV cases are among 20- to 29-year-olds.

Health Commissioner Dr. Ed Ehlinger said among people living with HIV/AIDS in Minnesota, communities of color and men who have sex with men continue to be overrepresented.
