Health officials in Minnesota are expressing concern after preliminary data on syphilis among women in the state last year reveals a significant rise over the prior year.

Preliminary data for 2015 show syphilis cases in women were up 63 percent compared to 2014. The increase is occurring primarily among women of child-bearing age in all racial and ethnic groups, including pregnant women.

“Minnesota has not seen this many reported cases of syphilis in women in more than 20 years,” said Dr. Ed Ehlinger, Minnesota Commissioner of Health. Eighty-seven percent of all female syphilis cases in 2015 were concentrated in the Twin Cities metropolitan area and 13 percent in Greater Minnesota.

“We are working with our public health partners to address this significant increase and are taking the steps needed to curb it,” Ehlinger said.

MDH preliminary data show half of the pregnant women with syphilis were from Greater Minnesota and half from the Twin Cities area. Within the past six months, three infants born to mothers with syphilis during their pregnancy were reported to the department. There were no reported cases among infants in the prior four years.

“The good news is that there is a test to detect syphilis and the disease can be cured with medication,” said Ehlinger. “The key is to get more people at risk of infection to get tested and for health care providers to do more screenings. Sexual partners of infected patients need to be tested and treated as well.”

Health officials noted it is important for health care providers to take a complete sexual history and test women with risk factors for syphilis. Risk factors include drug use, multiple sex partners, infection with other sexually transmitted diseases and prior syphilis infection. All pregnant women should be tested at three points during their pregnancy: the first visit with their doctor, the 28th week of pregnancy and at delivery.

“All women and their sexual partners can play a vital role in lowering the chances of getting or spreading syphilis,” said Ehlinger. “Learning about the symptoms and practicing prevention will make a difference.”

Syphilis is a sexually transmitted disease that can be a serious health threat if left untreated, particularly among pregnant women. In the most severe cases, untreated syphilis can lead to blindness, brain damage, heart problems and even death. Pregnant women, when infected and untreated, can pass syphilis onto their babies, leading to severe and life-threatening conditions in infants. Syphilis in pregnancy can also lead to stillbirth or premature birth.
