**6. Syphilis**

Syphilis is one of the most prevalent bacterial STDs caused by the *Treponema pallidum T. pallidum) bacterium*. It infects the genital area, lips, mouth, or anus of both men and women. Syphilis is transmitted between people by direct contact with a syphilis sore during vaginal, anal, or oral sex and can spread from a mother with syphilis to her unborn baby during pregnancy and childbirth. It is not transmitted through the use of the same toilet; wearing the patient's clothes, or even using food utensils [12].

It is a contagious disease that can cause serious health problems, such as arthritis, brain damage, dementia, and blindness, and may lead to death if left untreated. Syphilis is often difficult to diagnose, and the patient may not have any symptoms for years [1].
