The largest viruses, just visible by light microscopy, these were responsible for SMALLPOX and now cause cowpox (VACCINIA), orf and MOLLUSCUM CONTAGIOSUM, but not CHICKENPOX.

Due to large genome size of poxviruses ~200-300kb, many poxvirus genes are dispensable for growth of the virus in vitro or in vivo and their deletion frequently leads to virus attenuation for the natural host e.
Our studies suggest that despite their transient nature, gene expansions may provide a potent means of adaptation in poxviruses, allowing them to survive either immune or pharmacological challenges," Malik said.
Of the known poxviruses, a genus stands out due to its medical importance and because it serves as a model for studying the Orthopoxvirus viral family, which comprises the smallpox virus and Vaccinia virus (VACV).
Poxviruses are enveloped, linear, double-stranded DNA viruses in the order Caudovirales and family Poxviridae.

The Poxviridae is divided into two subfamilies: Entomopoxvirinae, that comprises insect poxviruses, and Chordopoxvirinae, that includes all poxviruses of vertebrates (2).
Avian poxviruses are members of the genus Avipoxvirus of the Poxviridae family, which comprises a group of morphologically similar, large and complex DNA viruses that have varied degrees of host specificity.
Poxviruses have evolved a wide-spectrum of open-reading frames (ORFs) encoding immunoregulators which bind host proteins and disrupt the antiviral immune response.
Washington, Jan 4 (ANI): Scientists have now identified a novel compound, which can stall virus replication, and thereby fight infection caused by poxviruses, like Monkeypox.
The next five chapters are devoted to understanding the diverse strategies used by clinically relevant human viruses to subvert host-interferon responses: herpes simplex virus, poxviruses, hemorrhagic fever viruses, influenza virus, and hepatitis C virus.
They believe that the poxviruses target migrating immune cells, which may explain how the viruses spread quickly through an infected body.
