The clinical features of syphilis, yaws, and bejel occur in multiple stages that affect the skin. The skin lesions observed in the early stage last for weeks or months. The skin lesions are highly infectious, and the spirochetes in the lesions are transmitted by direct contact. The lesions regress as the immune response develops against T ...
With nontreponemal tests, false-positive reactions can occur for a large number of reasons, the most common of which is other infections, both viral and bacterial. Additionally these tests may show false-negative when the patient's antibody titer is very high due to a hook effect (also called a prozone effect).

Bejel, or endemic syphilis, is a chronic skin and tissue disease caused by infection by the endemicum subspecies of the spirochete Treponema pallidum. Bejel is one of the "endemic treponematoses" ( endemic infections caused by spiral-shaped bacteria called treponemes ), a group that also includes yaws and pinta .
A new proven protocol in which doxycycline is used to prevent sexually transmitted infections — called doxyPEP — has been an apparent sleeper hit among gay and bisexual men.
