Official Answer

Both bacteria and viruses are so small that they can only be seen through a microscope, and both have the ability to cause infection, but that’s where the similarities end.

Bacteria
Bacteria are one-celled organisms that can be found naturally throughout our bodies and in our environment. Most are harmless and do not cause infection. Bacteria in our bodies help us to digest food, protect us against other bacteria or microbes, and provide nutrients for our body. Seen under a microscope they look like rods, balls, or spirals, and they can multiply quickly under the right conditions. Less than one percent of bacteria actually make us sick. Infections caused by bacteria include strep throat, tuberculosis, and urinary tract infections (UTI).
Antibiotics are available to treat most bacterial infections; however, it is often best to let your body’s own immune system fight them if it is able to.

Viruses
Viruses on the other hand, cannot live without a host, or another living creature to help them multiply. Viruses are smaller than bacteria and they attach themselves to another living cell and use that cells' genetic material to reproduce themselves. Most viruses cause disease. Examples of diseases caused by viruses include the common cold, herpes, shingles, measles, chickenpox, COVID-19 and AIDS.
Antibiotics will not treat a viral infection. Viral infections require either vaccinations to prevent them in the first place or antiviral drugs to inhibit their development.
