There are 9 types of Human Herpesviruses (HHV). Herpesviruses have some of the largest genomes among human viruses, often encoding hundreds of proteins. Their genomes are linear and nonsegmented, around 200 kb.
Here are the most common ones:
HHV-1 (alpha), is also HSV-1, Herpes Simplex Virus 1. It produces most cold sores.
HHV-2 (alpha), is also HSV-2, Herpes Simplex Virus 2. It produces most genital herpes.
HHV-3 (alpha), is also Varicella Zoster Virus. It produces chickenpox.
HHV-4 (gamma), is also EBV, Epstein-Barr Virus. It is one of the most common viruses in humans. EBV has a double-stranded DNA genome of 172kb for 85 genes. It is best known as the cause of infectious mononucleosis ("mono" or "glandular fever"). It shares common traits with the viruses that cause chickenpox, shingles, cold sores, and genital herpes.
HHV-5 (beta), is also CMV, Cytomegalovirus.
