Are herpes viruses retroviruses?

Therefore, although retrovirus and herpesvirus determine chronic infections, you see that the mechanisms are very different. In the case of retroviruses, they are due to their ability to remain integrated in the genome and to the low level of expression, while herpesvirus can hide from the immune system.

Is herpes 2 an RNA virus?

HSV is a nonenveloped virus that is 160 nm in diameter and has a linear, double-stranded DNA genome. HSV-1 and HSV-2 have approximately 50% homology, and homologous sequences are distributed throughout the genome map.

What are the 9 herpes viruses?
