Notes from the field: increase in gonorrhea cases in counties associated with American Indian Reservations -- Montana, January 2012-August 2014.

In May 2012, the Montana Department of Public Health and Human Services noted that 23 cases of gonorrhea were reported in Roosevelt County during October 2011-March 2012, compared with only three cases during January-September 2011. An analysis of surveillance data for Roosevelt County and the six other Montana counties most closely associated with American Indian (AI) reservations showed that, during 2000-2011, the annual incidence rates in the seven counties ranged from 9-43 cases per 100,000, compared with 4-19 cases per 100,000 for all the remaining 49 Montana counties, and 98-129 cases per 100,000 for the United States. Since May 2012, the rates have continued to increase in the seven counties.
