Syphilis: Symptoms, Causes, Treatment

What are the symptoms of syphilis?

Syphilis is a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum. The symptoms of syphilis vary depending on the stage of the infection. Syphilis progresses through several stages, each with its own set of symptoms:

  1. Primary syphilis: The first symptom of syphilis is usually a small, painless sore called a chancre. Chancres can appear on the genitals, anus, mouth, or other parts of the body. The chancre is usually firm, round, and small, and it heals on its own within a few weeks.
  2. Secondary syphilis: If the primary stage is not treated, the infection progresses to the secondary stage, which typically occurs 2-10 weeks after the chancre appears. Symptoms of secondary syphilis can include:
  • Skin rash, often on the palms of the hands and soles of the feet
  • Mucous membrane lesions (such as in the mouth or genitals)
  • Fever
  • Swollen lymph nodes
  • Sore throat
  • Patchy hair loss
  • Headaches
  • Weight loss
  • Muscle aches
  • Fatigue

These symptoms may come and go over the course of a few weeks or months.

  1. Latent syphilis: After the secondary stage, syphilis enters a latent (hidden) stage where there are no visible symptoms, but the bacteria remain in the body. Latent syphilis is divided into early latent (less than one year since secondary syphilis) and late latent (more than one year since secondary syphilis) stages.
  2. Tertiary syphilis: In some cases, syphilis can progress to the tertiary stage, which can occur years or even decades after the initial infection. Tertiary syphilis can cause severe complications such as damage to the heart, brain, nerves, eyes, liver, bones, and joints. This stage can be life-threatening.

It’s important to note that not everyone with syphilis will progress to the tertiary stage, and the infection can be effectively treated with antibiotics, especially in the early stages. Regular testing and early treatment by your healthcare provider are crucial to prevent complications and reduce the risk of transmitting the infection to others.

What are the causes of syphilis?

Syphilis is caused by infection with the bacterium Treponema pallidum. The bacterium is usually transmitted through sexual contact with an infected person, including vaginal, anal, or oral sex. It can also be transmitted from a pregnant woman to her unborn child during pregnancy or childbirth, which is known as congenital syphilis.

Syphilis is highly contagious during its primary and secondary stages when sores or rash are present. The infection can be spread through direct contact with these sores or rash, even if the infected person does not have symptoms. Syphilis cannot be spread through casual contact such as hugging, kissing, sharing utensils, or using the same toilet.

In rare cases, syphilis can be transmitted through blood transfusions or by using contaminated needles, such as those used for injecting drugs. However, these modes of transmission are uncommon due to strict screening and sterilization procedures in healthcare settings.

It’s important to practice safe sex and get tested regularly for sexually transmitted infections, including syphilis, to prevent the spread of the disease and receive early treatment if needed.

What is the treatment for syphilis?

Syphilis is a bacterial infection caused by the bacterium Treponema pallidum. It is treated with antibiotics, primarily penicillin. The type and duration of treatment depend on the stage of syphilis and the presence of any complications. Here is an overview of the treatment for syphilis:

  1. Primary, secondary, and early latent syphilis: The recommended treatment for these stages of syphilis is a single intramuscular injection of benzathine penicillin G. The dose and frequency depend on the stage of the infection. For those allergic to penicillin, alternative antibiotics such as doxycycline, tetracycline, or ceftriaxone may be used.
  2. Late latent syphilis or syphilis of unknown duration: Treatment for late latent syphilis or syphilis of unknown duration typically involves three weekly doses of benzathine penicillin G.
  3. Neurosyphilis: For syphilis that involves the nervous system (neurosyphilis), treatment usually involves intravenous (IV) penicillin G every 4 hours for 10-14 days. Other antibiotics such as ceftriaxone may be used in cases of penicillin allergy.
  4. Congenital syphilis: Infants born with syphilis may be treated with penicillin, depending on the stage of the disease. Treatment is typically administered intravenously.

It’s important to undergo regular follow-up testing to monitor the effectiveness of treatment. In some cases, additional treatment may be necessary if the infection does not respond to initial therapy or if there are complications. It’s also important for sexual partners of individuals with syphilis to be tested and treated if necessary to prevent reinfection and further transmission.
