The number of new HIV infections in Minnesota rose 13 percent in 2009, the biggest increase in 17 years, signaling the return of a health scourge that public health experts had hoped was under control.
After holding steady for several years, the number of new HIV cases in the state rose from 326 in 2008 to 368 last year.
The largest cluster of new cases was among gay and bisexual men aged 15 to 24 -- 77 cases, compared to 42 in the previous year.
In an unusual move, the Minnesota Department of Health released the annual numbers more than two months ahead of schedule, a reflection of officials' concern about the unexpected increase.
"This tells us that HIV/AIDS remains a significant health threat in Minnesota, and we need to take steps to strengthen our prevention efforts," said Dr. Sanne Magnan, Minnesota Commissioner of Health.
Peter Carr, manager of HIV and Sexually Transmitted Diseases for the Health Department, said the causes are complex. But they appear to include a growing complacency and ignorance about the disease among teenagers and young adults, combined with the efficiency of the Internet and social networking sites as a means for connecting gay men who are seeking casual sex. He said the increase was not the result of increased testing.
"It could be that people are not taking it seriously," Carr said.
That's what Darin Rowles hears from teenagers and young adults when he teaches the HIV 101 class for the Minnesota AIDS Project (MAP), an advocacy group.
