Surge in syphilis cases leads some providers to ration penicillin

For decades, rates of the sexually transmitted infection were low. But the Hamilton County Health Department in Chattanooga — a midsize city surrounded by national forests and nestled into the Appalachian foothills of Tennessee — was seeing several syphilis patients a day, Miller said. A nurse who had worked at the clinic for decades told Miller the wave of patients was a radical change from the norm.

What Miller observed in Chattanooga is reflective of a trend that is raising alarm bells for health departments across the country.

Nationwide, syphilis rates are at a 70-year high. The Centers for Disease Control and Prevention said Jan. 30 that 207,255 cases were reported in 2022, continuing a steep increase over five years. Between 2018 and 2022, syphilis rates rose about 80%. The epidemic of sexually transmitted infections — especially syphilis — is “out of control,” said the National Coalition of STD Directors.

The surge has been even more pronounced in Tennessee, where infection rates for the first two stages of syphilis grew 86% between 2017 and 2021.

But this already difficult situation was complicated last spring by a shortage of a specific penicillin injection that is the go-to treatment for syphilis. The ongoing shortage is so severe that public health agencies have recommended that providers ration the drug — prioritizing pregnant patients, since it is the only syphilis treatment considered safe for them. Congenital syphilis, which happens when the mom spreads the disease to the fetus, can cause birth defects, miscarriages, and stillbirths.

Across the country, 3,755 cases of congenital syphilis were reported to the CDC in 2022 — that’s 10 times as high as the number a decade before, the recent data shows. Of those cases, 231…
