What type of virus is equine herpesvirus classified as?

Equine herpesvirus is classified as a double-stranded DNA virus, which is why the answer is correct. This classification is based on the structure of the virus's genetic material, which consists of double-stranded DNA rather than RNA.

Double-stranded DNA viruses have distinct mechanisms for replication and interaction with host cells, leading to specific disease processes in equines, such as respiratory disease, abortion in pregnant mares, and neurological disease. Understanding the classification of equine herpesvirus is crucial for developing vaccines and treatments, as well as for managing outbreaks and understanding transmission dynamics within horse populations.
