Syphilis is a complex sexually transmitted disease (STD) caused by the bacterium Treponema pallidum (spp. pallidum). The initial
stage (primary syphilis) is characterized by a highly infectious painless open sore, called a chancre, at the site of infection.
Chancres occur mainly on the external genitals, vagina, anus, or in the rectum. Syphilis is passed from person to person through
direct contact with the chancre. Sexual transmission can also occur during the secondary stage of syphilis. An infant can
acquire syphilis through the placenta if the mother is infected. In later stages of the disease, the bacteria move throughout
the body, damaging many organs over time. The open nature of the syphilitic sores makes it easier to acquire HIV, if exposed,
or to transmit the virus, if infected. Public health intervention and education measures are crucial in eliminating syphilis.
