Which disease is caused by a DNA poxvirus?

Explanation:
Molluscum contagiosum is caused by a poxvirus, specifically molluscum contagiosum virus, a member of the Poxviridae family. Poxviruses are large, enveloped double‑stranded DNA viruses that replicate in the cytoplasm. This distinguishes them from other DNA viruses like herpesviruses (which cause varicella and herpes zoster) and adenoviruses (which cause adenovirus infections). Clinically, molluscum contagiosum presents as small, dome-shaped, flesh-colored papules with a central dimple and spreads by skin-to-skin contact or autoinoculation.
