Question: i have hsv 1 what does that mean?
Answer: HSV-1 is a subtype of the herpes virus that typically causes oral herpes. This is also known as cold sores. HSV-1 can also cause genital blisters that appear very similar to the genital blisters associated with HSV-2 virus. Any herpes sore or blister — regardless of its subtype — can burn, itch, or tingle.
