Herpes is a common viral infection that can cause sores and blisters on the skin and mucous membranes. There are two main types of herpes: herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2). HSV-1 is the most common type and usually causes oral herpes, while HSV-2 usually causes genital herpes.
While herpes is a lifelong infection, it can be managed with medication. People with herpes can live healthy, active lives and can donate blood if they meet certain criteria.
