The number of new cases of HIV or AIDS declined by 12 percent in Minnesota last year, the Minnesota Department of Health reported Monday.

In all, 292 cases were reported in 2011, compared with 331 the year before.

But officials said they're still concerned that numbers are rising among African-born men, who reported a 31 percent increase, as well as minority women.

"While the overall drop in cases is encouraging, it's concerning that we continue to see increases and higher rates among some of our communities," Peter Carr, HIV section manager of the Health Department, said in a statement released by the department.

Overall, the department reported a 9 percent increase in HIV infections or AIDS cases among Minnesota women who were African-born, African-American, Latina and Asian.

The vast majority of new cases (86 percent) were reported in the Twin Cities metropolitan area.

A total of 9,785 HIV/AIDS cases have been reported since the state began tracking AIDS in 1982 and HIV in 1985. There are an estimated 7,136 persons living with HIV in the state.
