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.
It appears people are not contagious during the incubation period of pink eye â the time of up to a few days between when they are exposed and when the symptoms begin. If your pink eye is caused by a common viral infection and no other complications occur, then your eyes should clear up within a few days to two weeks. Pink eye also can be caused by bacterial conjunctivitis, which â even with treatment such as prescription antibiotic eye drops â can last up to a month or longer. However, with this type of pink eye, people should no longer be contagious 24 hours after antibiotic treatment begins.
