Gonorrhea is a sexually transmitted disease (STD) that causes septic infection of the urinary and genital systems in men or women due to infection with the gonococcus bacteria, which can be transmitted in many ways. Gonorrhea is caused by the entry of the gonococcus bacteria into the body, causing infection and inflammation in the urinary and genital areas, with the gonococcus bacteria being the main causative agent. The gonococcus is a bacterium produced in the natural environment, but it is parasitic in the human body and can be easily killed after leaving the body, so the gonococcus that causes gonorrhea is mostly spread from person to person. Sexual intercourse is one of the main ways of its transmission. If an uninfected person has unprotected sex with an infected person, he or she is likely to be infected. In addition, since gonococcus causes symptoms in the genital and urinary areas, gonococcus is easily left on the patient’s underwear or when using the toilet, and if an uninfected person accidentally comes into contact with it, he or she may also become infected. After entering the body, gonococci mainly invade the genitourinary system. In men, the urethra becomes red, swollen, itchy, and painful, and there may be mucus-like or pus-like discharge from the urethra. In women, there are symptoms such as redness, swelling or erosion in the vulva and anus, pus-like discharge from the vagina and pain in the lower abdomen. Gonorrhea needs to be treated promptly with effective antibiotic-like medications. Gonorrhea is caused by infection with the gonococcus bacteria, which can be transmitted through sexual intercourse and direct contact, etc. Careful prevention is needed, and the disease should be treated with medication in a timely manner.
