👉 Syphilis is a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum. It can be contracted through sexual contact, but it can also be acquired from blood transfusions or contaminated equipment. Symptoms of syphilis include redness and swelling at the site of injection, pain during urination, and sometimes a feeling of unease or discomfort. Treatment for syphilis usually involves antibiotics, which may require several weeks to fully resolve the infection.
