What is the difference between bacteria and a virus?
in advance.

Viruses are smaller than bacteria and can't survive without a living host. A virus attaches itself to cells and usually reprograms them to reproduce itself. Also, unlike bacteria, most viruses do cause disease. Some virus-caused diseases include the common cold, AIDS, herpes, and chickenpox.

Hope This Helps! Have A Nice Day!!

Bacterias are alive and viruses are not. Viruses make you sick. Bacteria can be treated with antibiotics if they make a person sick.
