More Info


Syphilis is a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum. It is primarily transmitted through direct contact with syphilis sores, which can occur during sexual activity, including vaginal, anal, and oral sex. However, it is important to understand the nuances of transmission and the conditions under which syphilis can be contracted.

To answer your question directly: No, you cannot get syphilis without some form of sexual activity or direct contact with an infected person's sores. The bacterium that causes syphilis is not airborne and does not spread through casual contact, such as hugging or sharing utensils. The primary mode of transmission is through intimate sexual contact where there is direct exposure to the sores or lesions associated with syphilis.

Regarding the risk of contracting syphilis, it is generally considered low for individuals who do not engage in sexual activity. However, if you have had any form of sexual contact, even if it was not penetrative, there is still a risk if one of the partners is infected. It’s crucial to be aware of your partner's sexual health status and to engage in safe sex practices, such as using condoms, to reduce the risk of STIs.

As for the symptoms of syphilis, they can vary depending on the stage of the infection:
1. Primary Stage: The first sign of syphilis is usually a small, painless sore called a chancre, which appears at the site of infection (often on the genitals, anus, or mouth). This sore typically heals on its own within a few weeks.

2. Secondary Stage: If left untreated, syphilis can progress to the secondary stage, which may involve skin rashes, mucous membrane lesions, and flu-like symptoms. The rashes can appear as rough, red, or reddish-brown spots and may cover large areas of the body.

3. Latent Stage: After the secondary stage, the infection can enter a latent phase where there are no visible symptoms. However, the bacteria remain in the body.

4. Tertiary Stage: If syphilis is still untreated, it can progress to the tertiary stage, which can occur years later and may cause severe damage to organs such as the heart, brain, and nerves.

The "black spots" you mentioned on the genitals could be a concern, but they are not definitive indicators of syphilis. It is essential to consult a healthcare professional for an accurate diagnosis. They may perform a physical examination and recommend blood tests to check for syphilis and other STIs.

In summary, syphilis cannot be contracted without sexual activity or direct contact with an infected sore. If you have concerns about potential exposure or symptoms, it is advisable to seek medical attention promptly. Regular STI screenings are also recommended for sexually active individuals to ensure early detection and treatment of any infections.
