Conjunctivitis (pink eye) is a viral or bacterial infection of the conjunctiva (the filmy membrane that covers the inside of the eyelids and whites of the eyes). Symptoms include red, inflamed eyes that are itchy and watery. If accompanied by a viral infection, a runny nose and sore throat may also be present.
Conjunctivitis is extremely contagious, keep your child at home if they have symptoms to avoid infecting others. Conjunctivitis usually goes away after a few days, but your child may need medication if it lasts longer than a week.
