Can syphilis be transmitted through saliva?

Hello doctor, my job is to care for patients, and I am currently taking care of an elderly man who has syphilis.
Today, while feeding him, he accidentally choked and sprayed food, which ended up in my eyes.
I would like to know if I could be infected with syphilis this way.
Do I need to get tested?

Hello: First, let's confirm whether your grandfather's syphilis has been treated.
Generally, once it is known that someone has syphilis, treatment is usually initiated immediately.
If he has already been treated, he is effectively cured and cannot transmit the infection.
If he has not been treated yet, most elderly individuals with syphilis have latent syphilis, meaning they have had it for a long time and it is not very infectious.
Additionally, the cornea of the eye is not a common site for syphilis to manifest, and the bacteria are not typically found in saliva, so there is minimal risk if saliva comes into contact with the eyes.
There is no need to worry too much.

More Info

Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. It is primarily transmitted through direct contact with syphilitic sores, which are typically found on the genitals, anus, or mouth. The question of whether syphilis can be transmitted through saliva is a common concern, especially in situations where there is potential exposure to bodily fluids.

While syphilis is not commonly transmitted through saliva, it is theoretically possible if there are active sores in the mouth of an infected person. However, the risk of transmission through saliva is significantly lower compared to sexual contact. The primary modes of transmission for syphilis include sexual intercourse (vaginal, anal, or oral) with an infected person, and less commonly, from mother to child during pregnancy or childbirth.

In your specific situation, where you were feeding an elderly person with syphilis and experienced saliva exposure to your eyes, the risk of transmission is still considered low. The bacteria that cause syphilis are not typically present in high concentrations in saliva, and the mucous membranes of the eyes are not the primary route of infection. However, if there were any sores or lesions in the mouth of the infected individual, there could be a slight risk.

Given your concern, it is advisable to take the following steps:
1. Consult a Healthcare Provider: It is essential to discuss your exposure with a healthcare professional. They can provide personalized advice based on your specific situation and medical history.

2. Consider Testing: While the risk of transmission in this scenario is low, if you are feeling anxious or if there are any symptoms (such as sores, rashes, or unusual discharge), it may be prudent to undergo testing for syphilis and other sexually transmitted infections (STIs). Testing can provide peace of mind and ensure that any potential infections are detected early.

3. Monitor for Symptoms: Keep an eye out for any signs of syphilis, which can include sores, rashes, fever, or swollen lymph nodes. If you notice any of these symptoms, seek medical attention promptly.

4. Practice Safe Hygiene: In the future, ensure that you practice good hygiene when caring for individuals with known infections. This includes wearing gloves when handling bodily fluids and avoiding direct contact with sores.

5. Educate Yourself: Understanding how syphilis and other STIs are transmitted can help reduce anxiety and improve your ability to protect yourself and others. Resources from public health organizations can provide valuable information.

In summary, while the risk of contracting syphilis through saliva is low, it is not entirely absent, especially if there are active lesions present. Consulting with a healthcare provider and considering testing can help address your concerns and ensure your health and safety.
