Virus vs. Bacteria

A non-living infectious agent that needs a host versus a single-celled living organism.

The comparisoni

✗ Wrong

Antibiotics kill viruses.

✓ Correct

Antibiotics kill bacteria — viruses don't respond to antibiotics. Antivirals (or vaccines) target viruses.

The ruleii

BACTERIA = living. VIRUSES = need a host.

BACTERIA are single-celled living organisms; antibiotics target their cellular machinery. VIRUSES are smaller, not technically alive — they need a host cell to reproduce. Antibiotics don't work on them; antivirals or vaccines do.

Memory aidiii

Remember it like this

Bacteria live alone. Viruses need a host.
