What makes EKC different from other kinds of pink eye?
Affects cornea
One of the biggest differentiators of EKC is that it causes inflammation of your cornea, also known as keratitis. This usually happens around the fourth day after “pink eye” symptoms begin.
Viral source
EKC is specifically caused by adenoviruses, whereas bacterial conjunctivitis is caused by bacteria and allergic conjunctivitis is caused by allergens like pollen or dust.
More contagious
Unlike bacterial conjunctivitis, which can also spread but is less likely to cause widespread outbreaks, EKC spreads fast, especially in crowded settings. This is crucial to remember during school outbreaks when children might come into close contact with each other.
Medications not typically prescribed
While bacterial conjunctivitis may be treated with antibiotics, epidemic keratoconjunctivitis typically resolves on its own and does not benefit from antibiotic treatment since it's caused by a virus.
Longer lasting
While bacterial or allergic conjunctivitis may clear up quickly with treatment, EKC often persists, with symptoms going on for about two weeks or possibly longer.
