Is there a significant difference between "germ" and "virus"?
No, there isn't a significant difference. Actually, "germs" can be a "virus." "Germs" are viruses, bacteria, fungi, and protozoa that can cause us to get sick. A "virus" is a specific type of germ that needs another living host's cells to multiply/reproduce. Ex: We don't know much about the coronavirus. Ex: Wash the counters after cooking to kill any germs. Ex: The virus had me coughing for 3 weeks! Ex: She is such a germaphobe.
