Viral conjunctivitis
Viral conjunctivitis (pronounced: vahy-ruhl kuhn-jungk-tuh-vahy-tis), also known as pink eye, is a common, highly contagious infection of the conjunctiva - the clear layer that covers the white part of the eye and the inner surface of the eyelids.
Etymology
The term "viral conjunctivitis" is derived from the Latin virus meaning "poison" and conjunctiva, referring to the eye's outermost layer. The suffix "-itis" is from Greek -itis denoting diseases characterized by inflammation.
Symptoms
The primary symptoms of viral conjunctivitis include redness, itching, and watering of the eyes. Other symptoms may include a feeling of grittiness in the eyes, sensitivity to light (photophobia), and a sticky coating on the eyelashes (especially upon waking).
Causes
Viral conjunctivitis is most commonly caused by adenovirus, a type of virus that is often associated with the common cold. Other viruses that can cause conjunctivitis include herpes simplex virus, varicella-zoster virus, and picornavirus.
Treatment
There is no specific treatment for viral conjunctivitis; most cases will clear up on their own without treatment. However, symptomatic relief can be achieved through the use of lubricating eye drops and cold compresses. In severe cases, antiviral medication may be prescribed.
Prevention
Prevention of viral conjunctivitis involves good hygiene practices such as regular hand washing, not sharing personal items like towels or makeup, and avoiding close contact with people who have the infection.
