Viral conjunctivitis, also known as "pink eye," is a contagious infection of the conjunctiva, the thin membrane that covers the surface of the eyeball and inner lining of the eyelids. It is characterized by redness, swelling, irritation, and a watery or discharge-filled discharge from the eyes.
Viral conjunctivitis is primarily caused by a variety of common viruses, including adenovirus, herpes simplex virus, and enterovirus. The infection is easily spread through direct contact with the discharge from an infected person's eyes or by touching contaminated surfaces and then touching the eyes. It can also be transmitted through respiratory droplets from a cough or sneeze.
The condition typically begins with one eye and may spread to the other eye within a few days. Symptoms usually emerge within 1 to 3 days of exposure and can last up to 2 weeks. While viral conjunctivitis is generally a self-limiting condition and resolves on its own, it can cause significant discomfort and temporary vision impairment.
Treatment for viral conjunctivitis focuses on alleviating symptoms and preventing the spread of infection. This often involves the use of lubricating eye drops to relieve dryness and irritation, as well as antiviral medications in specific cases caused by the herpes simplex virus. It is important for individuals with viral conjunctivitis to practice good hand hygiene, avoid touching their eyes, and to avoid close contact with others to prevent the spread of the infection.
Overall, viral conjunctivitis is a common and contagious eye infection characterized by redness, discharge, and irritation. Prompt attention and appropriate precautions are necessary to manage the condition effectively and minimize its transmission.
The word "viral" comes from the Latin word "vīrus", which means "poison" or "slime". It was originally used to describe a toxic substance.
The term "conjunctivitis" can be traced back to the Latin word "conjunctīvus", which means "relating to a joining together". In medicine, it refers to the inflammation of the conjunctiva, the transparent membrane that covers the white part of the eye and the inner surface of the eyelids.
The plural form "conjunctivitides" is derived from the classical Latin plural suffix "-idēs" appended to the end of "conjunctivitis".
Therefore, "viral conjunctivitides" refers to multiple instances of inflammation of the conjunctiva caused by a viral infection.
