There is an area of intense confusion! 'Pink eye' refers to viral conjunctivitis;usually the child has a minimally itchy but very watery red eye. A thick discharge is not a part of classic pink eye. Often you can feel a swelling of the lymph node that lies on the side of the face between the eye and ear (just in front of the ear, actually). I don't think anyone knows for sure how long the kid is contagious but a good rule of thumb is about a week after onset, but once the redness and tearing go away, they are ok to go to school as long as they wash their hands (yeah, right). There is no need for any medication.
Lots of times people will call bacterial conjunctivitis 'pink eye', but it is not the same thing. This is the condition where you see the goopy stuff on the eye lashes of the red eye. I always give these kids an antibacterial ointment. There is no need to keep them out of school!
Good luck
