The possibility of contracting HPV (human papillomavirus), syphilis, or other diseases through saliva?


Hello, doctor.
I would like to ask if there is a high possibility of contracting diseases such as genital warts, syphilis, or other infections by ingesting someone else's saliva.
I wasn't paying attention and accidentally ate leftover food on the table after someone left, and I also used their utensils.
I'm really worried now and I'm not sure if I should quickly make an appointment for antibiotics or get any tests done tomorrow, Monday.

Hello, I would like to ask if the possibility of contracting warts, syphilis, or other diseases by consuming someone else's saliva is high? --> Not high (most sexually transmitted infections are transmitted through sexual contact).
I didn't pay attention and ate leftovers left on the table by someone else while dining out, and I even used their utensils.
I'm really worried now and don't know if I should quickly make an appointment for antibiotics or what tests I should do on Monday.
--> You can refer to the CDC's assessment of the risk of sexually transmitted infections related to safe sexual practices.
Wishing you good health.

More Info


When it comes to the transmission of sexually transmitted infections (STIs) such as HPV (human papillomavirus) and syphilis, it is important to understand the modes of transmission and the level of risk associated with various activities.
Firstly, HPV is primarily transmitted through direct skin-to-skin contact, particularly during sexual activities, including vaginal, anal, and oral sex. The virus can infect the genital area, mouth, and throat. However, HPV is not typically transmitted through casual contact such as sharing food or utensils. The likelihood of contracting HPV from sharing food or utensils is extremely low because the virus does not survive well outside the human body. HPV requires a conducive environment, such as moist skin or mucous membranes, to remain infectious. Therefore, eating food that has been in contact with another person's saliva does not pose a significant risk for HPV transmission.

Similarly, syphilis is primarily transmitted through direct contact with syphilis sores during sexual activity. While syphilis can be present in bodily fluids, including saliva, the transmission through sharing food or utensils is also considered highly unlikely. The bacteria that cause syphilis (Treponema pallidum) do not survive well outside the human body, and the risk of infection through casual contact is minimal.

In your specific situation, where you consumed food that may have been in contact with someone else's saliva, the risk of contracting HPV or syphilis is very low. If you are feeling anxious about potential exposure to STIs, it is always a good idea to consult with a healthcare professional. They can provide guidance based on your specific circumstances and any symptoms you may be experiencing.

If you are concerned about other STIs or have had potential exposure through sexual contact, it is advisable to get tested. Most STIs can be diagnosed through blood tests, urine tests, or swabs, depending on the infection. Regular screenings are important for sexually active individuals, especially if you have multiple partners or engage in unprotected sex.

In summary, the risk of contracting HPV or syphilis from sharing food or utensils is extremely low. The primary modes of transmission for these infections are through sexual contact. If you have concerns about your sexual health or potential exposure to STIs, seeking medical advice and testing is the best course of action. Remember, maintaining open communication with your healthcare provider about your sexual health is crucial for prevention and early detection of STIs.
