Gonorrhea
Reporting Obligations
Individuals who have or may have gonorrhea shall be reported to the local Health Unit. For community health professionals testing and treating gonorrhea infections, please review the following memo.
Epidemiology
Aetiologic Agent
The causative agent for gonorrhea is a gram-negative diplococcus, Neisseria gonorrhoeae.
Clinical Presentation
Many cases are asymptomatic. If symptoms do occur, they usually appear two to seven days after infection. Presentation and severity differs in males and females. In males, the most common presenting symptom is a painful, purulent urethral discharge usually with dysuria and increased frequency of urination as well as redness, itching and urethral swelling. Up to 10% of urogenital infections in men are asymptomatic.
Females present with initial urethritis or cervicitis which is frequently mild and can go unnoticed. Abnormal vaginal discharge and post-coital bleeding may occur and infection can progress to pelvic inflammatory disease. Up to 50% of urogenital infections in women are asymptomatic.
Pharyngeal and rectal infections can occur among those engaging in oral and anal sex. Most rectal and pharyngeal gonococcal infections are asymptomatic.
Modes of Transmission
Sexual contact via oral, vaginal, cervical, urethral or anal routes; in children, consider the possibility of sexual abuse; newborns: during delivery from infected mother.
Incubation Period
In individuals who display symptoms, the incubation period is usually 1–14 days.
Period of Communicability
Can extend for months if untreated. Effective treatment usually ends communicability within hours.
Risk Factors/Susceptibility
General susceptibility. Risk factors for transmission include:
- Sexually active youth under 25 years of age
- Men who have sex with men
- Those who have had contact with a person with proven gonorrhea infection or a compatible syndrome
- Sex workers and their sexual partners
- Street-involved youth
- Individuals with a history of gonorrhea or other STI infection
Diagnosis and Laboratory Testing
Neisseria gonorrhoeae is confirmed when detected in an appropriate clinical specimen (e.g., urogenital, rectal or throat (pharyngeal) swab, urine).
See Gonorrhea guide: Screening and diagnostic testing.
Treatment and Case Management
Treatment is under the direction of the attending health care provider. See Gonorrhea guide: Treatment and follow-up.
Regardless of test results, sex partners of a case should receive empiric treatment as soon as possible, as per the above treatment recommendations.
Patients and their contact can receive first-line treatment at no cost at a Sexual Health clinic.
