脓疱疮是一种常见的急性化脓性皮肤病,因流黄水、结黄痂故叫黄水疮。初起皮肤上有红斑,后转变为水泡,再发展为脓疱疮。脓疱疮可如米粒大或黄豆大小不等。泡破后露出鲜红的糜烂面,自觉瘙痒,常因搔抓而把病菌带到身体其他部位,凡是黄水流到处,即发新 Impetigo is a common acute suppurative skin disease. It is called yellow water sore due to yellowish water and yellow knots. There were red spots on the skin at the beginning, and later it turned into blisters and developed into impetigo. Impetigo can be as large as rice or beans. After the bubble breaks, it reveals a bright red erosion surface. It feels itchy and often brings germs to other parts of the body because of scratching.
