ADV (Adeno-associated virus) is a small, single-stranded DNA virus belonging to the Parvoviridae family that is not associated with any known disease in humans and requires a co-infection with a helper adenovirus or herpesvirus for its replication.
I'm sorry for any confusion, but "Amdovirus" is not a recognized term in medical or scientific literature. It is possible that you may have misspelled or misremembered the name of a specific virus or concept. If you have more information or context about where you encountered this term, I may be able to provide a more accurate and helpful response.
