Rapid rise in syphilis hits Native Americans hardest

From her base in Gallup, New Mexico, Melissa Wyaco supervises about two dozen public health nurses who crisscross the sprawling Navajo Nation searching for patients who have tested positive for or been exposed to a disease once nearly eradicated in the U.S.: syphilis.

Infection rates in this region of the Southwest — the 27,000-square-mile reservation encompasses parts of Arizona, New Mexico, and Utah — are among the nation's highest. And they're far worse than anything Wyaco, who is from Zuni Pueblo (about 40 miles south of Gallup) and is the nurse consultant for the Navajo Area Indian Health Service, has seen in her 30year nursing career.

Syphilis infections nationwide have climbed rapidly in recent years, reaching a 70-year high in 2022, according to the most recent data from the Centers for Disease Control and Prevention. That rise comes amid a shortage of penicillin, the most effective treatment. Simultaneously, congenital syphilis — syphilis passed from a pregnant person to a baby — has similarly spun out of control. Untreated, congenital syphilis can cause bone deformities, severe anemia, jaundice, meningitis and even death. In 2022, the CDC recorded 231 stillbirths and 51 infant deaths caused by syphilis, out of 3,761 congenital syphilis cases reported that year.

And while infections have risen across the U.S., no demographic has been hit harder than Native Americans. The CDC data released in January shows that the rate of congenital syphilis among American Indians and Alaska Natives was triple the rate for African Americans and nearly 12 times the rate for white babies in 2022.

“This is a disease we thought we were going to eradicate not that long ago, because we have a treatment that works really well,” said Meghan Curry O'Connell, a member of the Cherokee Nation and chief public health officer at the Great Plains Tribal Leaders' Health Board, based in South Dakota.

Instead, the rate of congenital syphilis infections among Native Americans (644.7 cases per 100,000 people in 2022) is comparable to the rate for the entire U.S. population in 1941 (651.1) — before doctors began using penicillin to cure syphilis. (The rate fell to 6.6 nationally in 1983.)

O'Connell said that's why the Great Plains Tribal Leaders' Health Board and tribal leaders from North Dakota, South Dakota, Nebraska and Iowa have asked federal Health and Human Services Secretary Xavier Becerra to declare a public health emergency in their states. A declaration would expand staffing, funding and access to contact tracing data across their region.

“Syphilis is deadly to babies. It's highly infectious, and it causes very severe outcomes,” O'Connell said. “We need to have people doing boots-on-the-ground work” right now.

In 2022, New Mexico reported the highest rate of congenital syphilis among states. Primary and secondary syphilis infections, which are not passed to infants, were highest in South Dakota, which had the second-highest rate of congenital syphilis in 2022. In 2021, the most recent year for which demographic data is available, South Dakota had the second-worst rate nationwide (after the District of Columbia) — and numbers were highest among the state's large Native population.

In an October news release, the New Mexico Department of Health noted that the state had “reported a 660% increase in cases of congenital syphilis over the past five years.” A year earlier, New Mexico reported only one case — but by 2020, that number had risen to 43, then to 76 in 2022.

Starting in 2020, the COVID-19 pandemic made things worse. “Public health across the country got almost 95% diverted to doing covid care,” said Jonathan Iralu, Indian Health Service chief clinical consultant for infectious diseases, based at the Gallup Indian Medical Center. “This was a really hard-hit area.”

At one point early in the pandemic, the Navajo Nation reported the highest COVID rate in the U.S.
