Syphilis is a disease that belongs to the STI (Sexually Transmitted Infection) group. It occurs when the bacterium called Treponema pallidum enters the body through mucous membranes. Located at openings in the body, mucous membranes are also found on the genitals, which is typically where a disease of this type is contracted. Damaged skin (e.g. cuts, burns, open sores, etc.) is also susceptible to letting the bacterium through.
There are three stages of development when it comes to syphilis. Stage one (primary syphilis) and stage two (secondary syphilis) aren’t lethal nor do they present with particularly dangerous symptoms. Treating syphilis is typically done with penicillin, and there’s a favorable success rate that follows it. However, due to the variety of symptoms and the fact that syphilis can lay dormant for extended periods, it is often hard to detect.
