Orthopoxvirus

Orthopoxvirus is a genus of viruses in the family Poxviridae and subfamily Chordopoxvirinae. The orthopoxvirus genus consists of 12 viruses including variola virus, vaccinia virus (VV), cowpox viruses (CV), monkeypox virus, and camelpox virus.

There are not many drugs available for orthopoxvirus treatment. The only product currently available for treatment of complications of Orthopoxvirus infection is vaccinia immunoglobulin (VIG). In 2021, brincidofovir was approved by FDA for the treatment of smallpox and tecovirimat was approved by EMA for the treatment of monkeypox in 2022. A few active compounds including interferon and interferon inducers, and a variety of nucleosides or nucleotides have been reported to have activity against orthopoxvirus.
