Syphilis was once a fading footnote in U.S. public health. It is now one of the fastest-rising sexually transmitted infections, and Alabama sits at the leading edge. State data shows some of the steepest increases in primary, secondary, and congenital syphilis in the country. Most people who carry it do not feel sick: the first sore is usually painless, the secondary rash mimics a dozen other conditions, and only a blood test gives a reliable answer.
Is syphilis really surging in Alabama, and what should I do about it?
Yes. CDC surveillance shows U.S. syphilis cases climbing year over year, and Alabama ranks among the highest-burden states for primary, secondary, and congenital syphilis. Early infection is often painless and easy to miss. Antibody tests typically detect syphilis from about 3 weeks after exposure, with most infections detectable by 6 weeks; 12 weeks is commonly used as a clinical threshold for considering exposure ruled out. A single dose of penicillin cures most early cases. At-home rapid blood tests offer a private way to screen, with lab confirmation recommended for any positive result.
Syphilis Is Surging Again, and Alabama Is at the Center
The CDC's most recent STI surveillance data confirms what local clinicians have been seeing for years: syphilis is no longer a controlled, declining infection in the United States. National cases of primary and secondary syphilis have climbed sharply since 2017, and congenital syphilis has risen even faster (CDC STI surveillance).
Alabama sits near the top of nearly every measure. The state has consistently ranked in the top tier for primary and secondary syphilis incidence, and the Alabama Department of Public Health has issued repeated provider alerts about catching the infection earlier in pregnancy (Alabama Public Health). Reporting on Alabama's congenital syphilis trend shows a sharp rise over the past decade, with newborn infections climbing from a small handful per year in the early 2010s into the dozens by the early 2020s. Each one of those infections was preventable with a routine blood test and a course of antibiotics during pregnancy.
U.S. primary and secondary syphilis cases have reached their highest levels in decades, per <a href="https://www.cdc.gov/sti-statistics/" target="_blank" rel="noopener">CDC STI Surveillance</a> data. Alabama's congenital syphilis trend has outpaced the national average, according to the Alabama Department of Public Health. The trajectory is not slowing on its own.
What Primary Syphilis Actually Looks Like
The classic first sign is a chancre. It is a single, round, firm sore that appears at the spot where the bacteria entered the body, typically the genitals, anus, or mouth. The sore is usually painless. It can be small enough to mistake for an ingrown hair, razor bump, or pimple, and it heals on its own in three to six weeks even without treatment (CDC syphilis basics).
The self-healing is what makes syphilis so easy to underestimate: the visible sore disappears, but the infection does not. Without treatment, the bacteria spreads through the bloodstream and reaches secondary syphilis, which often arrives weeks to a few months later as a non-itchy rash on the palms, soles, trunk, or all three. Mucous patches inside the mouth or on the genitals, hair loss in patches, swollen lymph nodes, and flu-like symptoms can join the rash.
Two features explain why so many cases get missed. First, the chancre does not hurt, so people do not seek care. Second, the secondary rash mimics dozens of common skin conditions, so even experienced clinicians sometimes miss the diagnosis on first presentation, particularly in regions where syphilis was rare for decades (CDC syphilis basics).
Why Alabama Cases Are Climbing
Alabama's surge is not random. It tracks with structural factors public-health officials have flagged for years.
Rural counties carry a heavy share of the burden. More than a quarter of Alabama residents live in counties with limited primary-care access, and a majority of the state's counties are designated as Health Professional Shortage Areas by the federal government. When the nearest STI clinic is an hour's drive away, screening drops.
Funding has lagged demand. State STI program budgets across much of the South have not kept pace with rising case counts, leaving public-health staff to triage outbreaks rather than prevent them. Several walk-in clinics have closed entirely, removing low-friction screening options from communities that already had few.
History matters too. The Tuskegee Syphilis Study, conducted from 1932 to 1972 in Macon County, withheld effective treatment from hundreds of Black men under the cover of research. The legacy of that betrayal continues to shape how some communities engage with public-health institutions today, a reality public-health researchers describe as medical mistrust rather than indifference.
This article is published by stdrapidtestkits.com, which sells at-home STI testing kits; clinic-based testing through your provider or county health department is equally valid and often free. Surveys consistently find that Alabama residents want to know their STI status. The barrier is not motivation; it is access, geography, and trust. Mail-order home testing addresses two of those three (privacy and geography). Lab-based confirmation and clinical follow-up still depend on the local healthcare system, which is exactly where state and county public-health funding has the most leverage.
How Syphilis Spreads (Not Just Penetrative Sex)
Syphilis transmits through direct contact with an active sore or rash, not just through penetrative sex. That distinction matters because it changes who counts as at risk.
Vaginal, anal, and oral sex all transmit syphilis if a sore is present at the contact site. Oral sex with a partner who has a chancre on the lip, tongue, or in the mouth can transmit the infection without any genital contact. Skin-to-skin contact with a sore on the inner thigh, scrotum, or vulva can transmit it even with consistent condom use, because condoms do not cover every surface where a chancre can appear.
A handful of non-sexual routes also exist. Sharing needles transmits syphilis along with other bloodborne infections. Healthcare workers have rarely been infected through accidental needlestick injuries. And vertical transmission from a pregnant person to a fetus is the most consequential non-sexual route by case count, accounting for the rise in congenital syphilis (WHO syphilis fact sheet).
What does not transmit syphilis: toilet seats, shared utensils, hugging, swimming pools, or doorknobs. Casual contact is not a transmission route, and framing the infection as something you can catch from a public surface mostly serves to add stigma without protecting anyone.
- Sexual contact with an active sore: vaginal, anal, or oral sex when a chancre or rash is present.
- Skin-to-skin contact: direct contact with a sore on the genitals, mouth, or surrounding skin, even outside areas a condom covers.
- Vertical transmission: from a pregnant person to the fetus during pregnancy or birth (congenital syphilis).
- Shared needles: blood-to-blood exposure through injection drug use or rare healthcare needlestick injuries.
- Not transmitted by: toilet seats, shared utensils, hugging, swimming pools, or doorknobs.
The Stages: Primary, Secondary, Latent, Late
Syphilis progresses in distinct stages. Treatment works at every stage, but earlier treatment prevents more damage. The table below summarizes what each stage looks like and how curability changes over time.
| Stage | Typical timing | Common signs | Curability |
|---|---|---|---|
| Primary | 10 to 90 days after exposure (avg ~3 weeks) | Painless single sore (chancre) at the infection site, often unnoticed | Yes, with one penicillin dose |
| Secondary | Weeks to a few months after primary | Non-itchy rash on palms, soles, or trunk; mucous patches; fever; swollen lymph nodes | Yes, with one penicillin dose |
| Early latent | Within first year of infection | No symptoms, but bacteria still detectable in blood | Yes, with one penicillin dose |
| Late latent / unknown duration | More than one year after exposure, asymptomatic | No symptoms; ongoing risk of progression | Yes, with three weekly penicillin doses |
| Tertiary / late | Years to decades later, untreated | Cardiovascular damage, neurosyphilis, gummas; possible permanent organ damage | Bacteria can be cleared, but existing damage is permanent |
Why Routine Testing in Pregnancy Matters Most
Congenital syphilis, where a pregnant person passes the infection to the fetus, is the single most preventable tragedy in this surge. CDC analyses of recent congenital syphilis cases consistently find that a majority involved a pregnant person who either was not screened in time or was screened but did not receive treatment before delivery (CDC STI surveillance).
Current CDC guidance recommends syphilis screening at the first prenatal visit for everyone, with repeat testing at 28 weeks and at delivery for people in higher-incidence areas, which includes much of Alabama. The blood test itself is inexpensive and routine. What proves harder in practice is timing the visit, getting the result back quickly, and completing treatment before delivery.
If you are pregnant or planning pregnancy in Alabama, ask your provider directly which trimester they screen in and whether they will retest later. Both questions matter. A single early-pregnancy negative is not enough on its own in a state where exposure risk during pregnancy is elevated.
The CDC's STI surveillance reporting describes the U.S. STI epidemic as ongoing and characterizes reversing the syphilis surge as dependent on sustained investment in testing access, partner services, and prenatal screening (<a href="https://www.cdc.gov/sti-statistics/" target="_blank" rel="noopener">CDC STI Surveillance</a>). Translation for an individual reader: do not wait for someone else to fix this. Routine personal testing is the part of the response you can control.
Testing Windows: When Is the Result Trustworthy?
A common worry after a possible exposure is timing. Test too early and a negative result is meaningless. Test too late and you have spent weeks anxious for no reason.
Most syphilis tests look for antibodies the immune system makes in response to the infection, not the bacteria itself. Antibodies typically become detectable about 3 weeks after exposure, with the great majority of infections detected by 6 weeks. A small fraction of people take longer, up to about 90 days, to seroconvert. In clinical practice, 12 weeks after a possible exposure is commonly used as the threshold for considering a negative antibody test reassuring. Worth knowing: CDC treatment guidelines specifically recommend that anyone whose sex partner had primary, secondary, or early latent syphilis within the past 90 days be treated presumptively, even if their own initial test is negative, because seroconversion may not yet have occurred (CDC STI Treatment Guidelines).
Rapid lateral-flow blood tests at home use the same antibody-based chemistry as the screening blood draw a clinic would order. They detect antibodies. They do not replace lab-based confirmatory testing, which is the regulatory gold standard. Any positive result on a home rapid test should be followed up with a clinic visit for confirmation and treatment.
Treatment Is Simple When Caught Early
For uncomplicated primary, secondary, or early latent syphilis, the CDC recommends a single intramuscular injection of long-acting penicillin G benzathine (CDC STI treatment guidelines). One shot. Most people become non-infectious within a few weeks, and follow-up blood tests track the antibody response over the months that follow.
Late latent syphilis or syphilis of unknown duration requires three weekly penicillin doses. Neurosyphilis, the rare late-stage involvement of the brain or spinal cord, requires intravenous penicillin in a hospital. Penicillin allergy can be managed with desensitization rather than alternative antibiotics, because no other antibiotic is as reliable for syphilis, particularly in pregnancy.
Treatment does not undo damage already done. The gap between exposure and treatment is the only variable an individual can control.
| Stage at treatment | CDC-recommended regimen |
|---|---|
| Primary, secondary, or early latent | Single intramuscular dose of penicillin G benzathine |
| Late latent or unknown duration | Three weekly intramuscular doses of penicillin G benzathine |
| Neurosyphilis (brain or spinal cord involvement) | Intravenous aqueous penicillin G, inpatient |
| Penicillin allergy (especially in pregnancy) | Desensitization to penicillin rather than substitute antibiotics |
Practical Next Steps If You're Worried
If you are reading this because something on your body looks off, or because a partner shared a positive test, the path forward has a few concrete steps.
1. Calendar the exposure. If it has been less than 3 weeks, an antibody test now will likely miss an early infection; testing at 6 weeks is reasonable, with a follow-up at 12 weeks if you want certainty. If it has been more than 3 weeks, test now.
2. Choose your testing channel. Public-health clinics offer free or low-cost STI testing in most Alabama counties; the Alabama Department of Public Health maintains a directory. Primary-care offices order syphilis blood tests routinely (records there are protected by federal HIPAA rules). At-home rapid antibody tests offer a private screen for people who cannot or will not visit a clinic, with lab confirmation for any positive.
3. If you test positive, do not panic and do not delay. Schedule treatment promptly. Notify recent partners; many county health departments offer anonymous partner-notification services. Plan to retest at standard clinical follow-up intervals (typically several months out, then again about a year later) to confirm the infection has cleared. The screen-confirm-treat-retest model is used internationally (NHS syphilis); your treating clinician will set the exact retest schedule based on the stage at treatment.
Less than 3 weeks since possible exposure: wait, then test at 6 weeks. Between 3 and 12 weeks: test now, and retest at 12 weeks if the first result is negative. More than 12 weeks with a negative antibody test is commonly considered reassuring in clinical practice. Symptoms at any point: test or see a clinician right away, regardless of timing.
FAQs
- How can I tell a syphilis sore apart from an ingrown hair or razor bump?
- By appearance alone, you often cannot. The chancre is firm and painless, while ingrown hairs and razor bumps tend to be tender or itchy. If a sore appears in the weeks after a possible exposure and feels nothing like a pimple usually does, treat that as a reason to test rather than a reason to wait it out.
- Can I get syphilis from oral sex?
- Yes. Oral sex transmits syphilis if either partner has a chancre on or in the mouth, on the lip, on the tongue, or on the genitals at the contact site. Because the chancre is painless and often hidden, partners may not realize a sore is present.
- How long after exposure can I get a reliable test result?
- Antibody tests typically detect syphilis from about 3 weeks after exposure, with the majority of infections detected by 6 weeks. In clinical practice, 12 weeks is commonly used as the threshold for considering a negative antibody test reassuring. Separately, CDC treatment guidelines recommend that sex partners of someone with primary, secondary, or early latent syphilis within the past 90 days be treated presumptively even if their own test is negative.
- Is at-home rapid syphilis testing accurate?
- Home rapid blood tests use lateral-flow antibody chemistry, the same general approach as a screening blood draw at a clinic. They are useful for screening. A positive result on a home test should always be confirmed at a clinic with a lab-based test before treatment, because confirmatory testing is the regulatory gold standard.
- What does the treatment actually involve?
- Early-stage syphilis: one penicillin shot. Late latent or unknown-duration: three weekly shots. Neurosyphilis: intravenous penicillin in a hospital. Treatment is highly effective when started early.
- Why is congenital syphilis rising so fast in Alabama?
- The dominant cause is missed or mistimed prenatal screening. Many people who pass syphilis to a fetus did receive prenatal care but were either not tested at the right point in pregnancy or did not complete treatment before delivery. CDC and state-level reviews of recent cases consistently find this pattern, not lack of effort from patients.
- Can syphilis go away on its own?
- The visible sore and the secondary rash both fade on their own. The infection itself does not. Untreated syphilis enters a latent stage that can persist for years before causing tertiary complications such as cardiovascular damage or neurosyphilis.
- How often should I get tested?
- CDC recommends annual STI screening for sexually active adults, more frequent screening (every 3 to 6 months) for people with multiple partners or other risk factors, and immediate testing for anyone with symptoms or a recent known exposure. Pregnant people in higher-incidence areas like Alabama should be screened at the first prenatal visit, at 28 weeks, and at delivery.
