Chlamydial Conjunctivitis: Transmission, Prevention, and Towel Safety

Chlamydial conjunctivitis is an eye infection caused by Chlamydia trachomatis (serovars D-K). It spreads through direct contact with infected genital secretions (semen, vaginal fluid) or ocular discharge, often via hands or shared items.

Transmission Routes

• Autoinoculation: Touching infected genitals then rubbing eyes.
• Partner-to-eye: Direct contact during sexual activity.
• Fomites: Shared towels, washcloths, eye makeup, or contact lenses contaminated with infected secretions.
• Neonatal: Passage through infected birth canal (ophthalmia neonatorum).

Symptoms

• Redness, irritation, watery or mucopurulent discharge.
• Often unilateral initially; may become bilateral.
• Follicular reaction on tarsal conjunctiva.
• Preauricular lymphadenopathy (unlike viral conjunctivitis).

Prevention & Hygiene

• Do not share towels, washcloths, pillows, or eye cosmetics.
• Wash hands thoroughly after toileting or genital contact.
• Use clean towel daily; launder in hot water (≥60°C / 140°F).
• Complete antibiotic treatment (oral azithromycin 1g single dose OR doxycycline 100mg BID × 7 days) for both patient and sexual partner(s).
• Abstain from sex until treatment completed and symptoms resolved.
• Screen for other STIs (gonorrhea, syphilis, HIV).

Important

Chlamydial conjunctivitis in adults almost always implies concurrent genital infection. Both ocular and genital sites must be treated to prevent reinfection and complications (e.g., pelvic inflammatory disease, epididymitis).
