Syphilis

Syphilis is a sexually transmitted infection that is triggered by the bacterium Treponema pallidum. The infection can be transmitted during the primary, secondary and early latent stages by direct contact with lesions of the skin or mucosa which can appear primarily in the genital and anal region but also in the mouth. It can be treated with antibiotics.
