"syphilis" 的定义和意义

What is "syphilis"?

Syphilis is a sexually transmitted infection (STI) caused by a bacterium called Treponema pallidum. It can be transmitted through sexual contact, including vaginal, anal, or oral sex, as well as through sharing contaminated needles. Syphilis progresses in stages and can cause symptoms like painless lumps, called chancres, on the genitals, mouth, or rectum during the primary stage, followed by a rash, fever, and flu-like symptoms in the secondary stage. If left untreated, syphilis can progress to more serious stages, affecting the heart, brain, and other organs, leading to severe complications. However, syphilis is treatable with antibiotics, especially in its early stages. Regular STI testing and practicing safe sex are crucial for prevention.
