Virology

The virions are small and non-enveloped.

The viruses are usually acquired soon after birth and may invade virtually any tissue in the body.^[2]

They are widespread in the pig population.^[3][4]

Genome

Iotatorqueviruses have a circular, single-stranded DNA genome. The genome is negative-sense.

Clinical

Postweaning multisystemic wasting syndrome has been causally associated with porcine circovirus type 2.^[5] The Iotatorquevirus have also been linked with this syndrome but a causative role—if one exists—has yet to be established.^[6]
