The number of new cases of HIV reported on the Navajo Nation has increased nearly five-fold since 1999, when there were 10 reported cases, The Daily Times in Farmington reported.
Forty-seven new cases of HIV, the virus that causes AIDS, were reported to the Navajo Area Indian Health Service in 2012, the agency reported recently.
That marked a 20 percent increase over the 39 new cases reported in 2011, according to The Daily Times.
The annual report released in mid-April marked the 25th year the Indian Health Service began treating HIV, or human immunodeficiency virus, The Daily Times said.
Since 1987, 436 cases of HIV and AIDS have been treated on the Navajo Nation, the paper reported. About 82 percent of the cases were in men and 18 percent in women.
