Explanation

Parvoviruses are the smallest known animal viruses, measuring only 18-26 nanometers in diameter. They are non-enveloped viruses with an icosahedral capsid and contain a single-stranded DNA (ssDNA) genome. Because of their tiny size and simple structure, parvoviruses rely heavily on the host cell's machinery for replication. An example is the human parvovirus B19, which causes fifth disease in children.
