If your child’s eyes are mildly red and water and no other symptoms are present, this may indicate irritation or allergy. However, if your child’s eyes are markedly red (including under the eyelids) and accompanied by thick, yellow or green drainage, he/she may have pink eye or conjunctivitis. The condition can be caused by virus, bacteria or allergies – only a doctor can determine the cause. Bacterial conjunctivitis is contagious if a child rubs his/her eyes and then touches another student or an object that another student uses and that student then rubs his/her eyes. For this reason, your child should remain home until treatment has begun or the symptoms are gone.
