What is the Rule of 8 for EKC?

Explanation:
The Rule of 8 for EKC points to the adenovirus serotype most classically linked with epidemic keratoconjunctivitis—serotype 8. EKC is a severe, highly contagious conjunctivitis caused by adenoviruses, and while several serotypes can cause EKC, type 8 is the one most historically associated with outbreaks, which is why this rule is remembered. The other options don’t describe a real, widely taught rule for EKC: the incubation isn’t a fixed eight days, subepithelial infiltrates don’t appear on a strict eight-day timeline, and there aren’t eight standardized stages of disease progression.
