25.1 Epidemiologic Review

25.1.1 Disease Information

Early Stage Syphilis: The ‘early’ definition includes primary, secondary & early non-primary non-secondary syphilis conditions. These are the first stages of syphilis that indicate a recent infection. Primary syphilis has a single or multiple sores at the point of infection, or where syphilis entered the body. The secondary stage causes skin rashes across the body, and more sores. More information can be found on the CDC syphilis fact sheet.

Overview: Syphilis is a bacterial infection caused by the bacterium Treponema pallidum. The disease is comprised of several stages depending on the length of infection. It is highly pathogenic when exposure occurs at the earliest stage of disease.

Symptoms: Symptoms may include painless lesions or chancres in the genital area or mouth, body rash, rash on the palms or hands or soles of the feet, patchy hair loss, and flu-like symptoms.

Transmission: The disease is spread through sexual contact, usually with a partner that has a syphilitic chancre (lesion or sore). Syphilis may also be transmitted during injection drug use when needles are shared with an infected person.

Treatment: Antibiotics are the recommended form of treatment.

Prevention Use of condoms, reducing the number of sexual partners, and getting tested every 3-6 months for high risk populations can help prevent the spread of disease.
