Answer by finette (157) Pink eye can be caused by fecal bacteria getting into the eye, but there are a lot of other possible causes as well. The most common cause of pink eye (also called conjunctivitis) is a viral infection, which can be spread from person to person just like a cold. Pink eye can also be caused by an allergic reaction.
Incubation period for pink eye caused by virus is around 12 hours to 3 days and a person can go back to work or school when the symptoms improve. That would be in 3 to 5 days. For bacterial infection, the person can go back to work 24 hours after antibiotic has been administered and symptoms start improving.
