Comments and suggestions: Pearl rash is not contagious, does not hinder health, and does not need treatment. But in order to prevent the disease from getting worse, we should pay attention to prevention and nursing. If the foreskin is too long, treat the foreskin as soon as possible; If it is stimulated by local secretion, Qin Ying will clean penis and perineum and change underwear frequently. I wish you the best of health!
