Syphilis is primarily transmitted through direct contact with syphilitic sores during vaginal, anal, or oral sex. The risk of getting syphilis from sharing a drink is very low but not impossible if the infected person has active syphilitic sores in or around their mouth. In such a case, the bacteria in the sores could be present in saliva and potentially transmitted when sharing drinks or eating utensils, especially if the saliva comes into contact with another person's mucous membranes. However, casual sharing of drinks without the presence of open sores carries a minimal risk. In summary:
- Syphilis is mainly spread through sexual contact with sores.
- Transmission through sharing drinks is rare but possible if mouth sores are present.
- Normal casual contact like sharing food, drinks, or utensils without sores is generally considered safe for syphilis transmission.
It is advisable to avoid sharing drinks or utensils with someone who has visible sores in or around the mouth to minimize even the small risk.
