virion

Complete virus unit

A virion is a single, complete virus particle—the form that exists outside a host cell.

It consists of genetic material (DNA or RNA) enclosed in a protein coat, sometimes surrounded by a lipid envelope.

Virions are inert until they infect a cell, at which point they hijack cellular machinery to replicate.

The researchers counted virions per milliliter of blood.
