Viral conjunctivitis basic overview
Viral conjunctivitis, commonly known as pink eye, is an inflammation of the outer membrane of the eye caused by various viruses including adenovirus and herpes simplex. Symptoms include redness, burning sensations, and watery discharge, with diagnosis typically made at home or medically through a history of contact and assessment of discharge. Preventive measures focus on hygiene and avoiding contact with infected individuals, while treatment often involves home care, including compresses and artificial tears, as antibiotics are not effective.
