Answer 2

Explanation:

A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea.

A person can be infected when aerosols or droplets containing the virus are inhaled or come directly into contact with the eyes, nose, or mouth.

• The virus can also spread in poorly ventilated and/or crowded indoor settings, where people tend to spend longer periods of time.
