FAIRBANKS - Health officials say the Interior is the only region in the state to avoid a large increase in the number of gonorrhea cases.
The State of Alaska Epidemiology Bulletin reports that cases of the sexually transmitted disease dropped in the Interior - from 76 in 2008 to 75 in 2009.
The rates doubled or tripled elsewhere as the state saw its biggest spike since the 1970s.
Health officials in Fairbanks say it's unclear why the trend missed the Interior.
The pattern also didn't hold true for chlamydia - another common STD. Infection rates rose both statewide and in Fairbanks, where the numbers climbed from 665 infections to 768.
