viral particles
Tiny disease carriers
Viral particles are individual units of a virus—the complete, infectious form that exists outside host cells.
Each particle, also called a virion, consists of genetic material (DNA or RNA) enclosed in a protein coat, sometimes with an outer membrane.
The sample contained millions of viral particles.
Scientists measure viral load by counting these particles in blood or tissue.
