Basics
Description
A sexually or vertically transmitted bacterial infection caused by Neisseria gonorrhoeae:
- Asymptomatic carrier states occur in men and women.
- System(s) affected: cardiovascular, musculoskeletal, nervous, reproductive, skin/exocrine
- Synonym(s): gonococcal infection; clap
Epidemiology
- Predominant age: 15 to 44 year olds account for 92% of cases; highest rate among those ages 20 to 24 years
- Predominant sex: men 213/100,000; women 146/100,000
Incidence
Centers for Disease Control and Prevention (CDC) 2018: 583,405 reported cases
Prevalence
Etiology and Pathophysiology
Infection requires four steps: (i) mucosal attachment—bacterial proteins bind to receptors on host cells, (ii) local penetration/invasion, (iii) local proliferation, (iv) inflammatory response or dissemination. N. gonorrhoeae spreads most commonly through sexual contact.
Genetics
Deficiency of late components of complement cascade (C7–C9) predisposes to disseminated disease.
Risk Factors
- History of previous gonorrhea infection or other STIs
- Sexual exposure to an infected individual without appropriate use of barrier protection (condom)
- New/multiple sexual partners
- Inconsistent condom use
- Commercial sex work or drug use
- Infants: infected mother
- Children: sexual abuse by infected individual
- Autoinoculation (finger to eye)
General Prevention
- Condoms offer partial protection and must be used appropriately during oral, anal, and vaginal sex.
