Patient EducationClinical

Gonorrhea

Gonorrhea is a sexually transmitted infection (STI). It is most common in young adults. The bacteria that cause gonorrhea can infect the genital tract, mouth, or anus. You can get gonorrhea during vaginal, oral, or anal sex with an infected partner. A pregnant woman can pass it to her baby during childbirth.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
