The only drug that treats syphilis during pregnancy is in short supply. Untreated, the disease can pass to newborns, killing them or leaving them with disabilities. As cases rise sharply, the government isn’t doing much to prevent shortages.

Last June, Pfizer, the lone U.S. manufacturer of the injections, notified the Food and Drug Administration of an “impending stock out” that it anticipated would last a year. The company blamed “an increase in syphilis infection rates as well as competitive shortages.”

Across the country, physicians, clinic staff and public health experts say that the shortage is preventing them from reining in a surge of syphilis and that the federal government is downplaying the crisis. State and local public health authorities, which by law are responsible for controlling the spread of infectious diseases, report delays getting medicine to pregnant people with syphilis. This emergency was predictable: There have been shortages of this drug in eight of the last 20 years.

Yet federal health authorities have not prevented the drug shortages in the past and aren’t doing much to prevent them in the future.

Syphilis, which is typically spread during sex, can be devastating if it goes untreated in pregnancy: About 40% of babies born to women with untreated syphilis can be stillborn or die as newborns, according to the CDC. Infants that survive can suffer from deformed bones, excruciating pain or brain damage, and some struggle to hear, see or breathe. Since this is entirely preventable, a baby born with syphilis is a shameful sign of a failing public health system.
