What causes syphilis?
-
Syphilis is caused by the bacteria called Treponema pallidum. This infection is most commonly spread through sexual contact. Bacteria leave the open sore of the infected person and enter through the mucous membranes or skin of the other person. Sometimes, syphilis may spread through other kinds of close contact, like kissing, or it can spread from a mother to her baby during birth or pregnancy. However, the bacteria can't live long outside of the body, so you can't get syphilis from things like toilets or swimming pools.

Transmission
Transmission of the bacteria usually occurs during vaginal, anal or oral sex. The syphilis bacteria are passed from person to person through direct contact with:
- The open sore (chancre) that appears during the primary stage.
- Mucous membrane or other sores during the secondary stage and sometimes during the latent stage.
Sores mainly occur on the external genitals, vagina, anus or rectum. Sores can also occur on the lips and in or around the mouth. The bacteria most commonly enter the body through mucous membranes, usually in the area around the genitals and urinary system.
In rare cases, syphilis enters the body through openings in the skin, such as cuts and scrapes or even through wet kisses, if the infected person has a sore on the mouth or lips. Syphilis may also be transmitted by using a needle previously used by an infected person. Syphilis can be transmitted through a blood transfusion. But this is very rare, because all donated blood in the United States and Canada is screened for some sexually transmitted infections (STIs). And syphilis bacteria cannot survive more than 24 to 48 hours in blood stored using modern blood-banking methods.
A pregnant woman with syphilis can pass the infection through the placenta and infect her baby any time during pregnancy or delivery ( congenital syphilis ).
Syphilis cannot be spread through casual contact with toilet seats, door knobs, swimming pools, hot tubs, bathtubs, shared clothing or eating utensils.
Having been infected with syphilis in the past does not protect a person from becoming infected again.
Incubation period
An incubation period is the time between exposure to a disease and the first symptom. A skin sore called a chancre is usually the first symptom of sexually transmitted syphilis. A chancre appears between 3 weeks to 3 months after a person has been infected with syphilis.
Contagious period
A person with syphilis can easily pass the infection (is contagious) to physically intimate partners when primary- or secondary-stage sores are present. But the person may be contagious for years, off and on and is always contagious whenever an open sore or skin rash from syphilis is present.
