Detailed explanation-1: -A virus is not a living organism and can only grow and reproduce in the cells of a host. Bacteria, by contrast, are single-celled organisms that produce their own energy and can reproduce on their own. While both can cause disease, bacteria also serve other vital and healthful roles in nature.
Detailed explanation-2: -Bacterial infections are caused by bacteria, while viral infections are caused by viruses. That’s the easy part. Differentiating between the two requires medical intervention since both may cause fever and irritability. And the treatments vary significantly.
Detailed explanation-3: -But what is the difference between these two types of germs? Bacteria are single cells that can multiply and cause infection. Viruses are much smaller than bacteria and need a host cell to reproduce. Viruses can only infect living cells, while bacteria can also infect non-living things like soil or water.
Detailed explanation-4: -Bacteria are single-celled, living organisms. They have a cell wall and all the components necessary to survive and reproduce, although some may derive energy from other sources. Viruses are not considered to be “living” because they require a host cell to survive long-term, for energy, and to reproduce.
