Acute conjunctivitis in children is not very different from acute conjunctivitis in adults. The course of acute conjunctivitis is usually 7-14 days, usually with simultaneous or sequential onset in both eyes, and the sequential onset is usually about 1-2 days apart. The disease progresses to a peak 3-4 days after the acute conjunctivitis infection and then gradually decreases and gradually improves or heals after 7-14 days. If a child has acute conjunctivitis, he or she should actively seek medical attention. Also, care should be taken to avoid the affected child rubbing his or her eyes with his or her hands to avoid transmission to other children. After acute conjunctivitis, care should be taken to isolate the child during the acute infectious period.
