Speaking in biological terms, viruses and bacteria are microscopic organisms that inhabit the bodies. They differ according to size and depending on the method of reproduction … Bacteria are living organisms that have only one cell, and that reproduce, like other cells, their DNA and RNA code.
Viruses are particles, of a single cell, but that cannot be considered as living beings, and that cannot reproduce themselves, need another cell to inoculate their own DNA to be this new cell, since infected, who reproduces the virus.

Bacteria are therefore considered independent units that reproduce alone and therefore have the facility to survive in all types of environments.
The virus, despite not being alive, can remain dormant for thousands of years waiting to find a valid host to sow its DNA seed and reproduce. The virus usually penetrates into a cell and imposes its genetic code.
Most bacteria are not only harmless to humans, but even beneficial because they break down organic matter and destroy harmful parasites. Viruses, unlike bacteria, are all dangerous and harmful. Antibiotics kill bacteria but viruses resist more easily. Many viruses like the flu, the only solution is to wait for it to happen. Although there are vaccines that are the weakened viruses themselves, which allow the blood to create antibodies, so, in this way, when the strong virus arrives, be fought.
