Understanding how syphilis spreads helps explain why it remains a public health concern despite being easily curable. The bacterium Treponema pallidum enters the body through tiny breaks in the skin or mucous membranes during sexual contact. Its infectivity is tied to the presence of active lesions, which contain high concentrations of the bacteria. As the disease progresses through stages, the number of visible lesions and the amount of bacteria decrease, reducing transmissibility. However, the infection does not disappear on its own; without treatment, it can persist silently and later cause severe health problems. This guide explains each stage's infectiousness, how syphilis is diagnosed, and how it differs from similar conditions.
