Common sexually transmitted diseases include gonorrhea, syphilis, genital warts, AIDS, genital herpes, etc. When a sexually transmitted disease occurs, there are usually some special symptoms. In women, there are often purulent secretions in the vagina and local swelling and pain; men may experience burning, itching, and swelling at the urethral opening, along with some sticky secretions, often accompanied by frequent urination, urgent urination, and painful urination. If it's syphilis, there is usually a hard lump in the genital area with superficial ulcers, which is a manifestation of primary chancre. In patients with genital warts, there typically appear nipple-like or cauliflower-like growths around the genitals and anus. If infected with HIV, the early stages usually involve fever, as well as symptoms like nausea, vomiting, whole-body rash, and swollen lymph nodes.
