The secondary stage of syphilis typically lasts for a variable period, generally ranging from 3 to 12 weeks or up to several months. During this phase, the skin lesions associated with the infection eventually disappear spontaneously.12
It is important to note that syphilis is a serious, infectious condition that requires professional medical intervention. If you suspect you have been exposed to or are experiencing symptoms of syphilis, you should seek medical attention immediately. Penicillin and other antibiotics are highly effective at treating the disease and preventing its progression to more severe, potentially fatal stages.3
