Syphilis

Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. It is spread through contact with the mucous membranes, such as during intercourse, or through direct contact with an open sore or lesion of an infected person. Syphilis is an important public health issue because it increases the risk of HIV infection, newborn infections, and other sexually transmitted infections. Early symptoms include a fever, swollen lymph nodes, and a rash. If left untreated, it can lead to serious and permanent damage to the heart, brain, nerves, and other organs. Treatment with antibiotics can eliminate the infection and prevent long-term complications.
