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.
When pink eye is caused by certain bacteria or viruses, the infected person can be contagious for several days to several weeks or more. Fortunately, people do not appear to be contagious during the incubation period  the time between when they are exposed and when pink eye symptoms begin. Schools and day care centers often require a child diagnosed with pink eye to stay home until the condition is resolved.
