What is Syphilis and How to Avoid it

  • April 8, 2023

Sexually transmitted infections (STIs) are a growing global health concern, with millions of new infections occurring annually. One such infection is syphilis, which has impacted human health for centuries. Despite advances in medical knowledge and available treatments, syphilis remains a common and dangerous infection across the world. This article will provide professional guidance on understanding what syphilis is, its symptoms in men and women, its effects, prevention strategies, and available treatments.

What is Syphilis?

Syphilis is a sexually transmitted bacterial infection caused by the bacterium Treponema pallidum. Although primarily transmitted through sexual contact, it can also spread from a pregnant woman to her fetus or occasionally through blood transfusions. If left untreated, this infection can progress through four distinct stages, with each stage presenting its unique set of symptoms and complications.

Symptoms in Men and Women

The symptoms of syphilis are not always obvious, and many individuals may not realize they are infected. There are four stages of syphilis infection: primary, secondary, latent, and tertiary. The symptoms vary across the four stages, and as the infection progresses, they tend to become more severe.

Primary Syphilis: The first sign of infection is typically a small, painless sore called a chancre. In men, this sore typically appears on the penis, while in women, it is usually within the vagina or on the cervix. The chancre eventually heals itself without treatment, but the infection progresses if left untreated.

Secondary Syphilis: A few weeks after the chancre has healed, individuals may experience symptoms such as fever, muscle aches, fatigue, enlarged lymph nodes, and a rash. The rash, which does not itch, typically appears on the palms of the hands or soles of the feet but can occur elsewhere on the body.

Latent Syphilis: At this stage, the infection becomes “dormant,” meaning there might be no visible symptoms. However, the infection continues to progress.

Tertiary Syphilis: If not treated, syphilis can cause severe, even life-threatening complications. Tertiary syphilis can result in damage to the heart, brain, blood vessels, nervous system, bones, and joints.

Effects on Men and Women

The effects of syphilis on both men and women can be severe if left untreated. These effects include:

Neurosyphilis: This refers to neurological complications caused by the infection, including dementia, meningitis, or stroke.

Cardiovascular syphilis: Untreated syphilis can lead to inflammation and damage of the blood vessels, increasing the risk of aneurysms or heart failure.

Pregnancy complications: Pregnant women infected with syphilis have an increased risk of miscarriage, stillbirth, premature birth, and passing the infection to their newborn, which can cause severe health issues for the baby.


The best way to avoid syphilis is by taking preventive measures, such as:

Practicing safe sex: Using condoms and dental dams consistently and correctly can significantly reduce the risk of contracting syphilis.

Regular testing: Routine STI screenings, especially for sexually active individuals with multiple partners, can help identify syphilis in its early stages.

Communication: Being open with sexual partners about STI testing and status is essential for maintaining a mutually healthy sexual relationship.

Limiting the number of sexual partners: Reducing the number of sexual partners can lower the risk of contracting syphilis.


If diagnosed early, syphilis can be cured using appropriate antibiotics, such as penicillin. It is important to follow the prescribed treatment plan and complete the entire course of antibiotics, even if symptoms have subsided. However, these treatments cannot reverse any damage already caused by syphilis. Regular follow-up tests are necessary to ensure the infection is entirely gone and prevent reinfection.


Syphilis is a dangerous infection that can cause severe health issues in both men and women. By understanding its symptoms, and effects, and practicing prevention methods, individuals can protect themselves and their partners from this potentially debilitating infection. Early diagnosis and treatment are essential to prevent irreversible damage and complications from syphilis.
