Syphilis

Syphilis is a bacterial sexually transmitted infection (STI) caused by the bacterium Treponema pallidum. It can affect both men and women and is primarily spread through sexual contact, including vaginal, anal, and oral sex.

Syphilis is characterized by a series of stages, each with different symptoms. In the early stages, the most common symptoms are small, painless sores called chancres, which can appear on the genital area, anus, mouth, or lips. If left untreated, syphilis can progress to later stages, which can cause a range of symptoms, including rashes, fever, joint pain, and problems with the nervous system.

If left untreated, syphilis can cause serious health problems, including brain damage, blindness, and death. In addition, pregnant women with syphilis can pass the infection to their babies, which can cause serious health problems or death in newborns.

Syphilis can be treated with antibiotics, and early treatment is important to prevent serious health problems. Regular testing and prompt treatment are important for maintaining sexual health and preventing the spread of STIs. If you have had unprotected sex or suspect you may have an STI, it is important to get tested.
