BILLINGS, Mont. (AP) — Federal health officials have trained tribal officials in Montana and Wyoming to use software to track population health data.

The Rocky Mountain Tribal Epidemiology Center brought in a trainer from the U.S. Centers for Disease Control and Prevention to teach the Epi Info 7 software in mid-August.

RMTEC epidemiologist Jordan Vandjelovic says the tribes can now develop their own surveys and track and analyze the data collected by them. The five-day training was attended by members of Montana's Blackfeet, Crow, Northern Cheyenne and Fort Belknap reservations and Wyoming's Eastern Shoshone and Northern Arapaho tribes.

The CDC did not respond to an interview request.
