What is the primary route of transmission for gonococcal conjunctivitis in adults?

• A. Autoinoculation from a genital infection or direct sexual contact
• B. Airborne transmission
• C. Waterborne transmission
• D. Fomite-mediated transmission

Answer: (A)

Autoinoculation from a genital infection or direct sexual contact is the primary route because Neisseria gonorrhoeae rests on mucous membranes and is transmitted through close mucosal contact with infected secretions. In adults, the eye becomes involved when someone touches infected genital secretions and then rubs or otherwise contacts the ocular surface, or through direct contact with an infected partner during sexual activity. This organism is not typically spread through the air, contaminated water, or fomites, since it requires direct mucosal exposure to infectious secretions rather than environmental routes. Clinically, gonococcal conjunctivitis in adults often presents with rapid onset and copious purulent discharge, underscoring the need to address the mucosal source and prevent further transmission.
