When Mai Yang is looking for a patient, she travels light. She dresses deliberately — not too formal, so she won’t be mistaken for a police officer; not too casual, so people will look past her tiny 4-foot-10 stature and youthful face and trust her with sensitive health information. Always, she wears closed-toed shoes, “just in case I need to run.”
Yang carries a stack of cards issued by the Centers for Disease Control and Prevention that show what happens when the Treponema pallidum bacteria invades a patient’s body. There’s a photo of an angry red sore on a penis. There’s one of a tongue, marred by mucus-lined lesions. And there’s one of a newborn baby, its belly, torso and thighs dotted in a rash, its mouth open, as if caught midcry.
It was because of the prospect of one such baby that Yang found herself walking through a homeless encampment on a blazing July day in Huron, Calif., an hour’s drive southwest of her office at the Fresno County Department of Public Health. She was looking for a pregnant woman named Angelica, whose visit to a community clinic had triggered a report to the health department’s sexually transmitted disease program. Angelica had tested positive for syphilis. If she was not treated, her baby could end up like the one in the picture or worse — there was a 40% chance the baby would die.
Ms. Yang knew, though, that if she helped Angelica get treated with three weekly shots of penicillin at least 30 days before she gave birth, it was likely that the infection would be wiped out and her baby would be born without any symptoms at all. Every case of congenital syphilis, when a baby is born with the disease, is avoidable. Each is considered a “sentinel event,” a warning that the public health system is failing.
The alarms are now clamoring. In the United States, more than 129,800 syphilis cases were recorded in 2019, double the case count of five years prior. In the same time period, cases of congenital syphilis quadrupled: 1,870 babies were born with the disease; 128 died. Case counts from 2020 are still being finalized, but the CDC has said that reported cases of congenital syphilis have already exceeded the prior year. Black, Hispanic, and Native American babies are disproportionately at risk.
There was a time, not too long ago, when CDC officials thought they could eliminate the centuries-old scourge from the United States, for adults and babies. But the effort lost steam and cases soon crept up again. Syphilis is not an outlier. The United States goes through what former CDC director Dr. Tom Frieden calls “a deadly cycle of panic and neglect” in which emergencies propel officials to scramble and throw money at a problem — whether that’s Ebola, Zika, or COVID-19. Then, as fear ebbs, so does the attention and motivation to finish the task.
The last fraction of cases can be the hardest to solve, whether that’s eradicating a bug or getting vaccines into arms, yet too often, that’s exactly when political attention gets diverted to the next alarm. The result: The hardest to reach and most vulnerable populations are the ones left suffering, after everyone else looks away.
Ms. Yang first received Angelica’s lab report on June 17. The address listed was a P.O. box, and the phone number belonged to her sister, who said Angelica was living in Huron. That was a piece of luck: Huron is tiny; the city spans just 1.6 square miles. On her first visit, a worker at the Alamo Motel said she knew Angelica and directed Ms. Yang to a nearby homeless encampment. Angelica wasn’t there, so Ms. Yang returned a second time, bringing one of the health department nurses who could serve as an interpreter.
They made their way to the barren patch of land behind Huron Valley Foods, the local grocery store, where people took shelter in makeshift lean-tos composed of cardboard boxes, scrap wood ,and scavenged furniture, draped with sheets that served as ceilings and curtains. Yang stopped outside one of the structures, calling a greeting.
“Hi, I’m from the health department, I’m looking for Angelica.”
The nurse echoed her in Spanish.
Angelica emerged, squinting in the sunlight. Ms. Yang couldn’t tell if she was visibly pregnant yet, as her body was obscured by an oversized shirt. The two women were about the same age: Ms. Yang 26 and Angelica 27. Ms. Yang led her away from the tent, so they could speak privately. Angelica seemed reticent, surprised by the sudden appearance of the two health officers. “You’re not in trouble,” Ms. Yang said, before revealing the results of her blood test.
Angelica had never heard of syphilis.
“Have you been to prenatal care?”
Angelica shook her head. The local clinic had referred her to an obstetrician in Hanford, a 30-minute drive away. She had no car. She also mentioned that she didn’t intend to raise her baby; her two oldest children lived with her mother, and this one likely would, too.
Ms. Yang pulled out the CDC cards, showing them to Angelica and asking if she had experienced any of the symptoms illustrated. No, Angelica said, her lips pursed with disgust.
“Right now you still feel healthy, but this bacteria is still in your body,” Ms. Yang pressed. “You need to get the infection treated to prevent further health complications to yourself and your baby.”
The community clinic was just across the street. “Can we walk you over to the clinic and make sure you get seen so we can get this taken care of?”
Angelica demurred. She said she hadn’t showered for a week and wanted to wash up first. She said she’d go later.
Ms. Yang tried once more to extract a promise: “What time do you think you’ll go?”
“Today, for sure.”
Syphilis is called The Great Imitator: It can look like any number of diseases. In its first stage, the only evidence of infection is a painless sore at the bacteria’s point of entry. Weeks later, as the bacteria multiplies, skin rashes bloom on the palms of the hands and bottoms of the feet. Other traits of this stage include fever, headaches, muscle aches, sore throat, and fatigue. These symptoms eventually disappear and the patient progresses into the latent phase, which betrays no external signs. But if left untreated, after a decade or more, syphilis will reemerge in up to 30% of patients, capable of wreaking horror on a wide range of organ systems. Dr. Marion Sims, president of the American Medical Association in 1876, called it a “terrible scourge, which begins with lamb-like mildness and ends with lion-like rage that ruthlessly destroys everything in its way.”
The corkscrew-shaped bacteria can infiltrate the nervous system at any stage of the infection. Ms. Yang is haunted by her memory of interviewing a young man whose dementia was so severe that he didn’t know why he was in the hospital or how old he was. And regardless of symptoms or stage, the bacteria can penetrate the placenta to infect a fetus. Even in these cases the infection is unpredictable: Many babies are born with normal physical features, but others can have deformed bones or damaged brains, and they can struggle to hear, see, or breathe.
From its earliest days, syphilis has been shrouded in stigma. The first recorded outbreak was in the late 15th century, when Charles VIII led the French army to invade Naples. Italian physicians described French soldiers covered with pustules, dying from a sexually transmitted disease. As the affliction spread, Italians called it the French Disease. The French blamed the Neopolitans. It was also called the German, Polish, or Spanish disease, depending on which neighbor one wanted to blame. Even its name bears the taint of divine judgement: It comes from a 16th-century poem that tells of a shepherd, Syphilus, who offended the god Apollo and was punished with a hideous disease.
By 1937 in America, when former Surgeon General Thomas Parran wrote the book “Shadow on the Land,” he estimated some 680,000 people were under treatment for syphilis; about 60,000 babies were being born annually with congenital syphilis. There was no cure, and the stigma was so strong that public health officials feared even properly documenting cases.
Thanks to Dr. Parran’s ardent advocacy, Congress in 1938 passed the National Venereal Disease Control Act, which created grants for states to set up clinics and support testing and treatment. Other than a short-lived funding effort during World War I, this was the first coordinated federal push to respond to the disease.
Around the same time, the Public Health Service launched an effort to record the natural history of syphilis. Situated in Tuskegee, Ala., the infamous study recruited 600 black men. By the early 1940s, penicillin became widely available and was found to be a reliable cure, but the treatment was withheld from the study participants. Outrage over the ethical violations would cast a stain across syphilis research for decades to come and fuel generations of mistrust in the medical system among Black Americans that continues to this day.
With the introduction of penicillin, cases began to plummet. Twice, the CDC has announced efforts to wipe out the disease — once in the 1960s and again in 1999.
In the latest effort, the CDC announced that the United States had “a unique opportunity to eliminate syphilis within its borders,” thanks to historically low rates, with 80% of counties reporting zero cases. The concentration of cases in the South “identifies communities in which there is a fundamental failure of public health capacity,” the agency noted, adding that elimination — which it defined as fewer than 1,000 cases a year — would “decrease one of our most glaring racial disparities in health.”
Two years after the campaign began, cases started climbing, first among gay men and later, heterosexuals. Cases in women started accelerating in 2013, followed shortly by increasing numbers of babies born with syphilis.The reasons for failure are complex; people relaxed safer sex practices after the advent of potent HIV combination therapies, increased methamphetamine use drove riskier behavior and an explosion of online dating made it hard to track and test sexual partners, according to Dr. Ina Park, medical director of the California Prevention Training Center at the University of California San Francisco.
But federal and state public health efforts were hamstrung from the get-go. In 1999, the CDC said it would need about $35 million to $39 million in new federal funds annually for at least five years to eliminate syphilis. The agency got less than half of what it asked for, according to Jo Valentine, former program coordinator of the CDC’s Syphilis Elimination Effort. As cases rose, the CDC modified its goals in 2006 from 0.4 primary and secondary syphilis cases per 100,000 in population to 2.2 cases per 100,000. By 2013, as elimination seemed less and less viable, the CDC changed its focus to ending congenital syphilis only.
Since then, funding has remained anemic. From 2015 to 2020, the CDC’s budget for preventing sexually transmitted infections grew by 2.2%. Taking inflation into account, that’s a 7.4% reduction in purchasing power. In the same period, cases of syphilis, gonorrhea and chlamydia — the three STDs that have federally funded control programs — increased by nearly 30%.
“We have a long history of nearly eradicating something, then changing our attention, and seeing a resurgence in numbers,” said David Harvey, executive director of the National Coalition of STD Directors. “We have more congenital syphilis cases today in America than we ever had pediatric AIDS at the height of the AIDS epidemic. It’s heartbreaking.”
