"It's been on the increase for the last two to three years. But this past year was significant," said Lynn Meinor, manager of communicable disease prevention for the state Department of Health.
Over the past five years gonorrhea has been diagnosed primarily among homosexual men and other males considered high risk. But this latest increase has been in women, said Meinor. "It appears to have shifted to the heterosexual population," she said.
Only 27 percent of cases were among females in 2012, compared to 40 percent in 2013, health department data show.
"We're trying to get the word out to family practice doctors and OB-GYNs that they should be screening regularly and taking thorough sexual health histories," said Meinor.
Most at risk are middle-aged men and women living along the Wasatch Front. Two-thirds of the cases were among non-Hispanic whites.
As with most communicable diseases, densely populated Salt Lake County accounted for the lion's share of cases 72 percent, said Lynn Beltran, epidemiology supervisor for the Salt Lake County Health Department.
"Everyone is at risk," said Beltran, who stressed that 50 percent of those who are infected don't have symptoms.
Gonorrhea is treatable, though the bacteria have become resistant to many antibiotics over the years. As a result, the U.S. Centers for Disease Control and Prevention (CDC) revised treatment guidelines.
There is no evidence of bacterial resistance in Utah, Meinor said. But the new CDC guidelines still hold: a single-dose injection plus oral antibiotics taken either as a single dose or twice a day for seven days is now required.
