The definition of a virus (from the Latin virusmeaning toxin or poison), is a sub-microscopic infectious agent that is unable to grow or reproduce outside of a host cell.

Each viral particle, or virion, consists of genetic material, DNA or RNA, within a protective protein coat called a capsid. The capsid shape varies from simple helical and icosahedral (polyhedral or near-spherical) forms, to more complex structures with tails or an envelope. Viruses infect all cellular life forms and are grouped into animal, plant and bacterial types, according to the type of host infected.

Why is it difficult to define virus?

Viruses are difficult to define because they are acellular entities that can only replicate inside host cells, leading to questions about whether they are living or non-living. Additionally, viruses exhibit significant diversity in structure, genetic material, and replication strategies, making it challenging to come up with a single definition that encompasses all virus types.
