How do viruses differ from bacteria in the way it causes infections?

Answer 1

A bacterium is a single-celled, often parasitic microorganism without a distinct nucleus or an organized cell structure. It has cytoplasm and a cell wall, but no true nucleus. Various species are responsible for decay, fermentation, nitrogen fixation, and many plant and animal diseases.

Bacteria are classed in a kingdom of their own, prokaryota (although, this kingdom may now be regarded as two separate kingdoms, archaea and bacteria).

A virus is a submicroscopic parasitic particle consisting of a strand of nucleic acid surrounded by a protein coat (capsid). It does not have cytoplasm or a nucleus and can only replicate within a host cell (has parasitic nature).

Viruses are not considered to be independent living organisms as the only characteristic of life they show is reproduction.

That is, bacteria are LIVING while viruses are NON-LIVING.

Answer 2

A virus is a small infectious agent that can replicate only inside the living cells of organisms, while a bacteria is a living single-celled, prokaryote micro-organism,

so the difference is the way they reproduce, a virus does it by entering a cell and injecting it with his RNA, causing it to reproduce other viruses inside the cell until all the energy of that cell is depleted, and then the cell burst open, you are getting sick because when a virus strikes a lot of cells get infected resulting in you getting sick, a bacteria works different because it doesn't infect cells, it attacks them, and eats them for ground products, for his cell division, so the difference is that a virus needs a cell for reproducing, while a bacteria can reproduce on itself, and the reason it causes infections is because they both destroy cells of the host body.
