Viruses categorized by infection site, transmission, lesions, and diseases.

Group of viruses that replicate in the nucleus with double-stranded DNA.

Viruses with a circular double-stranded DNA genome, causing diseases like smallpox.

A virus that is part of the major viral pathogens affecting human skin.

Complete viral particles that include nucleocapsid and envelope for herpesviruses.

Structure in herpesviruses that associates nucleocapsid and envelope with regulatory proteins.

Cells formed due to the presence of certain herpesviruses, visible in Tzanck smear.

Icosaheral structure, large size, lipoprotein envelope, and ability to cause latency.

Herpes simplex virus type 2, primarily causing genital herpes.

An antiviral medication used when herpes viruses are resistant to acyclovir.

The virus that causes chickenpox (varicella) and shingles (zoster).

An infectious disease caused by the varicella-zoster virus, characterized by an itchy rash and flu-like symptoms.
