Syphilis, a disease caused by the Treponema pallidum bacterium continues to be an important public health problem. Syphilis is a sexually transmitted infection (STI) and can be transmitted by all types of intimate contact including genital, oral, and anal sex. Use of a condom during all sexual activity can reduce the risk of infection.
