This means the infection can be transmitted through sexual contact, including kissing and intercourse, or through the use of unclean needles. Unfortunately there is no cure, but in most cases the infection clears within 4-8 weeks. Some people remain contagious for the rest of their lives. Hep B can be prevented with a vaccine, and many health professionals recommend that college students be inoculated as a matter of course. Condoms during vaginal, oral and anal sex can help prevent the spread of Hep B, but it can also be passed through kissing and other sexual touching.
Syphilis goes through several stages and for most of the time has no symptoms.
Symptoms include painless sores or open ulcers on the genitals or mouth and body rashes. The final stages of syphilis can result in severe damage to the nervous system and major organs. If left untreated the syphilis organism can stay in the body for life, causing disfigurement, neurological disorders, or death. Syphilis can be transmitted through anal, oral, and vaginal intercourse and kissing. Fluid from open syphilis sores is incredibly infectious, but syphilis is less contagious during latent stages where symptoms are not present.
