Gonorrhea is a sexually transmitted infection caused by the bacteria Neisseria gonorrhoeae, which can infect the genital tract and other areas through sexual contact. Common symptoms include painful urination and abnormal discharge. If left untreated, gonorrhea can lead to complications like pelvic inflammatory disease and infertility. It is diagnosed through laboratory testing of samples from infected areas and treated with antibiotics. Consistent condom use and getting tested are effective ways to prevent the spread of this STI.
