The prevalence of all cutaneous manifestations directly associated with COVID-19 infection is unknown, but the number of reports is rapidly increasing and provisional knowledge is rapidly evolving. Skin manifestations reported can be classified into (1) manifestations unspecifically indicating possible infectious diseases, i.e. maculopapular exanthem, urticaria and erythema multiforme, and (2) manifestations more specifically indicating COVID-19 infection, i.e. varicella-like, livedo reticularis or chilblain-like eruptions. The latter appear to be associated with thrombovascular events and vascular pathologies.
COVID-19 感染直接相关的所有皮肤表现的流行率尚不清楚，但报告数量正在迅速增加，临时知识也在迅速发展。已报告的皮肤表现可分为 (1) 提示可能传染病的非特异性表现，即斑丘疹性出疹、荨麻疹和多形红斑，和 (2) 更特异性提示 COVID-19 感染的表现，即水痘样、网状青斑或冻疮样疹。后者似乎与血栓血管事件和血管病变有关。
