Why People Come to KMD Law After a Syphilis Diagnosis
Most people who call us after a syphilis diagnosis are not looking for a spectacle. They want to understand whether the law recognizes what happened to them, whether they can protect their privacy, and whether anyone will take a claim seriously when the other person has more money, more lawyers, or more influence.
We built this practice around those exact concerns.
Keith M. Davidson has spent years handling STD and civil sexual assault matters that other firms treat as too sensitive, too complicated, or too politically inconvenient. Our results in STD transmission cases, including recoveries of $9.5 million, $5 million, and $3 million in herpes and STD negligence matters, reflect a simple principle: when the evidence is there, we pursue it.
That experience matters in a syphilis case. These claims live at the intersection of medicine, privacy, and proof. Timing of tests, the difference between actual knowledge and constructive knowledge, communications that look ordinary until they are read in context, and the long medical tail of untreated infection all have to be assembled carefully.
We know how to do that work without turning your life into a public exhibit.
Syphilis in the United States: What the Public Health Data Shows
Syphilis is not a historical footnote. It is a present public health problem, and the numbers help explain why so many people only learn they were exposed after the damage has already begun.
According to the Centers for Disease Control and Prevention’s provisional Sexually Transmitted Infections Surveillance, 2024, the United States reported 190,242 syphilis cases of all stages; still a substantial national burden even after a 9.1 percent decline from 209,249 cases in 2023.
Primary and secondary syphilis, the most infectious stages, fell about 22 percent year over year, to 41,496 cases. Those declines are welcome. They are not a reason to treat a new diagnosis as minor.
Congenital syphilis remains the most urgent warning in the data. CDC reported nearly 4,000 congenital syphilis cases in 2024; 3,941, a 1.6 percent increase from 2023, and the twelfth consecutive year of increase. Congenital syphilis is roughly 700 percent higher than it was a decade earlier.
In the same reporting year, more than 2.2 million combined cases of chlamydia, gonorrhea, and syphilis were still recorded, and overall STI morbidity remained about 13 percent higher than ten years prior.
Those figures do not decide a lawsuit. They do, however, undercut a common defense posture: that syphilis is rare, that “everyone should have known the risk,” or that a diagnosis is too ordinary to justify legal accountability. A bacterial infection that can silently damage the heart, brain, eyes, and hearing, and that can be passed to a child during pregnancy, is not a private inconvenience.
When transmission happens because someone failed to disclose what they knew or should have known, the law has a place in that story.
What Is Syphilis?
Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. Public health agencies often call it “the great imitator” because its signs can look like other illnesses, or disappear for long stretches while the infection continues inside the body.
The infection moves through stages. Each stage can look different, and some people notice almost nothing at first. That quiet period is one reason syphilis is so often discovered late, and one reason a partner’s “I didn’t know” explanation deserves a careful look rather than automatic acceptance.
- Primary syphilis: Primary syphilis typically begins with one or more sores, called chancres, at the spot where the bacteria entered the body. That can be the genitals, anus, rectum, lips, or mouth. Chancres are often firm, round, and painless. They last about three to six weeks and can heal on their own. Healing is not a cure. Without treatment, the infection remains.
- Secondary syphilis: Secondary syphilis may bring a rash, including on the palms of the hands or soles of the feet, along with fever, swollen lymph nodes, sore throat, patchy hair loss, headaches, muscle aches, weight loss, or fatigue. These symptoms can also fade without treatment. The infection does not leave with them.
- Latent syphilis: In the latent stage, there are no visible signs. A person can carry syphilis for years, feel well, and still have an untreated infection. Early latent syphilis (generally within the first year) and late latent syphilis are distinguished for medical and public health purposes. From a legal standpoint, latency is often the period in which a defendant claims ignorance, even when prior symptoms, prior testing, or prior partners should have prompted them to find out.
- Tertiary syphilis and infection of the nervous system: Tertiary syphilis can appear 10 to 30 years after the original infection. It can damage the heart and blood vessels, the brain and nervous system, and other organs, and it can be fatal. Neurosyphilis, ocular syphilis, and otosyphilis — infection of the brain and spinal cord, the eyes, and the ears — can occur at any stage. Symptoms may include severe headache, muscle weakness, confusion, personality change, vision loss, hearing loss, tinnitus, or vertigo.
Syphilis is curable with the right antibiotics prescribed by a clinician. Treatment does not automatically undo injury that has already occurred. That distinction matters in a lawsuit. A course of penicillin may clear the bacteria and still leave medical bills, follow-up testing, fertility concerns, pregnancy risks, and the emotional weight of knowing the infection was avoidable.
How Syphilis Is Transmitted
Syphilis spreads through direct contact with an infectious sore during vaginal, anal, or oral sex. A sore may be hidden inside the vagina, rectum, or mouth, which means a person can transmit the infection even when nothing is visible to a partner. Women can also pass syphilis to a baby during pregnancy. That is congenital syphilis.
Syphilis is not spread by sitting on a toilet seat, sharing clothes, using the same utensils, or casual contact with objects. Those myths still circulate, and they are sometimes used to muddy a claim. The medically relevant route, in the cases we see, is intimate contact with an infectious lesion or, in pregnancy, transmission to a child.
A few points are especially important if you are considering a claim:
- A condom reduces risk. It does not erase a duty to disclose a known or suspected infection, and it does not make transmission impossible if a sore is outside the covered area.
- Consent to sexual activity is not consent to an undisclosed infection. Courts have recognized that distinction for decades.
- A partner does not need a formal lab result in hand to be responsible. In many jurisdictions, including California, liability can attach when a person knew or had reason to know they were infected; for example, because of symptoms, a prior diagnosis, a doctor’s warning, or a recent partner who tested positive.
- You can get syphilis more than once. Prior treatment does not create immunity. Reinfection is medically possible and is sometimes used, unfairly, to attack a plaintiff’s credibility.
If the person who exposed you held power over you, transmission can occur in a setting where saying “no,” insisting on testing, or asking hard questions did not feel safe. The law can still examine what that person knew and what they chose not to say.
The Impact of Syphilis
A syphilis diagnosis is not only a lab result. It changes how you move through medical appointments, relationships, pregnancy planning, and, for many people, trust. The harm we document in these cases is both physical and personal.
Short-term impacts:
- Painful or painless sores that require medical evaluation and can be mistaken for other conditions.
- Rash, fever, swollen glands, fatigue, hair loss, and other flu-like symptoms during secondary infection.
- Urgent testing, antibiotic treatment, and follow-up bloodwork to confirm the infection is responding.
- The need to notify other partners, which can expose private details you never intended to share.
- Anxiety while waiting for results, repeating tests, and learning whether the infection has already involved the eyes, ears, or nervous system.
- Disruption of work, intimacy, and daily life during diagnosis and early treatment.
Long-term impacts:
- Neurosyphilis, with possible headache, cognitive change, difficulty walking, or dementia-like symptoms.
- Ocular syphilis and vision damage, including the risk of blindness.
- Otosyphilis, with hearing loss, tinnitus, or vertigo.
- Cardiovascular syphilis years later, including aortitis, aortic aneurysm, and valve disease.
- Gummatous disease that can destroy tissue in skin, bone, or organs.
- In pregnancy, miscarriage, stillbirth, preterm birth, low birth weight, or a baby born with congenital syphilis, which can cause cataracts, deafness, seizures, developmental injury, or death.
- Increased vulnerability to other infections, including HIV, because sores can make transmission easier.
- Ongoing medical monitoring, specialist visits, and the knowledge that some injury may not fully reverse even after the bacteria are cleared.
There is also the harm that does not show up on an MRI. People in these cases often describe shame they did not earn, fear of dating again, strain in a marriage, and the particular isolation that comes from being infected by someone others still treat as respectable
If that person has a public profile or control over your livelihood, the emotional injury is frequently compounded by the sense that speaking up will cost you more than staying quiet. We take that injury seriously.
Can You Sue Someone for Giving You Syphilis?
Yes. In many states, including California, you may bring a civil claim against a person who transmitted syphilis to you if they knew, or reasonably should have known, that they had a sexually transmitted infection and failed to disclose it or take reasonable steps to prevent transmission.
The principle is straightforward: a person who knows or has reason to know they are infected owes a duty of care to a sexual partner.
Model jury instructions in California address negligent sexual transmission of disease. Other states reach similar results under ordinary negligence, battery, fraud or misrepresentation, and, in some facts, intentional infliction of emotional distress.
A syphilis transmission lawsuit is typically considered a personal injury case. It is not the same thing as a criminal prosecution. Willful exposure can, in some places and for some infections, also raise criminal issues, but you do not need a prosecutor to file charges in order to seek compensation. You can pursue a civil claim on your own with your own lawyer and with privacy protections that a criminal file often cannot offer.
Consent to sex is not a complete defense. The question is whether you consented to the risk that was actually present. If the other person concealed a diagnosis, lied about testing, ignored symptoms, or used their authority to discourage questions, the fact that the encounter itself was not a stranger assault does not end the analysis.
What Damages Can You Recover in a Syphilis Transmission Lawsuit?
Compensation in a syphilis case is meant to address the full reach of the harm: the medical course you are now on, the work you missed, the relationships that changed, and the fear that does not resolve when the first antibiotic injection is over.
Every case is different. The categories below are the ones we most often evaluate.
- Past and future medical expenses. Testing, treatment, specialist care, imaging, pregnancy-related care, and long-term monitoring if the infection involved the nervous system, eyes, heart, or hearing.
- Lost income and diminished earning capacity. Time away from work for appointments and illness, and, in severe cases, a lasting effect on your ability to work.
- Pain and suffering. Physical symptoms, invasive treatment, and the bodily experience of an infection you did not choose.
- Emotional distress and mental anguish. Anxiety, depression, loss of trust, humiliation, and the particular distress of being infected by someone who had power over you.
- Loss of enjoyment of life and intimate relationships. Including strain on a marriage or partnership and the difficulty of rebuilding a private life after a diagnosis.
- Loss of consortium. A spouse or partner may have a related claim for the impact on the relationship.
- Harm related to pregnancy and children. If syphilis affected a pregnancy or a newborn, the damages analysis expands to that medical and human cost.
- Punitive damages. Available in some cases when the conduct was reckless, fraudulent, or intentional; for example, a known diagnosis that was actively concealed. Punitive damages exist to punish and to deter, not merely to reimburse bills.
No ethical lawyer can promise a number before the records are in. What we can say is this: the seriousness of syphilis, the duration of medical follow-up, and the quality of proof about what the other person knew are the facts that move compensation.
What Must Be Proven to Win a Syphilis Transmission Lawsuit?
A strong syphilis claim is built on evidence. The precise elements depend on the legal theory and the jurisdiction, but most successful cases answer the same core questions.
- The defendant had syphilis at the relevant time. Medical records, test dates, treatment history, and, when available, expert review of staging help establish that the infection predated your exposure.
- You acquired syphilis from that person. Causation is often the most contested issue. Timing of your negative and positive tests, the absence of other plausible sources during the window of infection, communications about exclusivity, and medical expert testimony all matter. You do not need a confession, but you do need a coherent medical and factual timeline.
- The defendant knew or should have known. Actual knowledge includes a prior diagnosis, a positive test, or a clinician’s warning. Constructive knowledge can include visible sores, a rash on the palms or soles, a partner who notified them, or circumstances that would have led a reasonable person to get tested before exposing someone else.
- The defendant failed to disclose or failed to take reasonable precautions. Silence, a false claim of recent negative tests, pressure not to use protection, or the use of status to shut down questions can all be part of the breach.
- You did not knowingly accept that risk. If you were told the person was “clean,” if testing was misrepresented, or if you had no reason to know, that supports the claim. Prior knowledge of the specific infection is different from general awareness that sex carries some risk.
- You suffered legally recognizable harm. A documented diagnosis, treatment, complications, and the personal consequences that followed.
Evidence in these files is often quieter than people expect. Text messages about testing. A photo of a rash a defendant asked you not to mention. Pharmacy records. An old diagnosis the person told friends about but not you. Calendar records that fix dates. We gather that material carefully, and we do it in a way that is meant to keep your name from becoming the story.
There is also a clock. Statutes of limitation for personal injury claims are often two years from the date you discovered, or reasonably should have discovered, the infection and its likely source; though the exact rule depends on the state.
Waiting because the other person is powerful is understandable. It can also put the claim at risk.
How a KMD Law STD Lawyer Can Help After Syphilis Transmission
You do not have to arrive with a completed investigation. You do not have to know the name of the legal theory that fits. You have to be willing to tell us what happened, as you remember it.
When we take on a syphilis transmission case, our work typically includes:
- A confidential consultation in which we listen to the full context: the relationship, the power imbalance, the medical timeline, and what you want the case to achieve.
- A clear-eyed assessment of liability, causation, damages, and the statute of limitations in the relevant jurisdiction.
- Collection of medical records, laboratory results, and, where appropriate, consultation with medical experts who can speak to staging, transmission windows, and long-term risk.
- Preservation of communications, financial records, and other evidence before it disappears.
- Strategic decisions about how the case is filed, including privacy protections available in the court where the claim belongs.
- Negotiation aimed at a discreet resolution when that serves you, and trial preparation when it does not.
- A willingness to proceed against defendants who expect their status to end the conversation.
We work on a contingency fee in these matters, which means our fee comes from a recovery, not from a retainer. Discretion is not a slogan on our site. It is how the work gets done. High-profile and high-net-worth defendants often have public relations teams and lawyers whose first move is to make the injured person feel small.
Our first move is to make the record complete. You will not be asked to minimize what happened in order to keep the other person comfortable.
