What is herpes 6 virus? i was told when i was younger that i had tested positive? what does that virus have to do with hiv?

Childhood herpes: Let me start by saying this has NOTHING to do with HIV. Human Herpesvirus 6 (HHV-6) is a set of two closely related herpes viruses known as HHV-6A and HHV-6B that infect nearly all human beings, typically before the age of two. The acquisition of HHV-6 in infancy is often symptomatic, resulting in childhood fever, diarrhea, and exanthem subitum rash (commonly known as roseola).
