Acute Hemorrhagic Conjunctivitis

Acute Hemorrhagic Conjunctivitis is a human viral disease characterized by inflammation of the conjunctiva accompanied by subconjunctival hemorrhage. It represents a specific clinical presentation within the broader spectrum of viral conjunctivitis, distinguished by its hemorrhagic features. The condition is formally classified in international disease coding systems as B30.3 (ICD-10) and 9A60.1 (ICD-11).

Source-backed clinical detail specific to the hemorrhagic presentation is not yet available. General viral conjunctivitis features include redness of the affected eye, swelling of the conjunctiva, excessive tearing, and a watery discharge. The condition may affect one or both eyes and typically presents with irritation, burning, or scratchiness. Pre-auricular lymph node swelling may occur, and the infection usually begins in one eye before potentially spreading to the other. Visual acuity is typically preserved, and pupils remain normally reactive.

Source-backed epidemiological detail specific to Acute Hemorrhagic Conjunctivitis is not yet available. General viral conjunctivitis accounts for approximately 80% of adult conjunctivitis cases, with adenoviruses responsible for 65% to 90% of viral cases. Viral conjunctivitis frequently occurs alongside upper respiratory tract infections, common cold symptoms, or sore throat. The condition spreads readily among individuals in close contact.

Source-backed transmission detail specific to Acute Hemorrhagic Conjunctivitis is not yet available. General viral conjunctivitis is easily spread among people through direct contact with infected individuals or contaminated surfaces. The infection may accompany other symptoms of upper respiratory illness.

Source-backed risk group detail specific to Acute Hemorrhagic Conjunctivitis is not yet available. For general viral conjunctivitis, adults represent the primary demographic affected by viral causes, whereas bacterial conjunctivitis predominates in pediatric populations.

Source-backed prevention detail specific to Acute Hemorrhagic Conjunctivitis is not yet available. For general viral conjunctivitis, prevention is partly achieved through handwashing, consistent with measures for other contact-transmitted viral infections.

Acute Hemorrhagic Conjunctivitis should be monitored as a distinct viral conjunctivitis entity with hemorrhagic features. The available sources provide general viral conjunctivitis epidemiology (approximately 80% of adult cases, adenoviral predominance) but lack AHC-specific transmission dynamics, outbreak patterns, or geographic distribution data. Surveillance systems should note this condition separately from other conjunctivitis etiologies while recognizing that detailed epidemiological characterization requires specialized clinical or microbiological confirmation sources.
