Detailed explanation-1: -On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive.
Detailed explanation-2: -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-3: -As you might think, bacterial infections are caused by bacteria, and viral infections are caused by viruses. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren’t effective against viruses.
Detailed explanation-4: -A virus cannot replicate alone; instead, it must infect cells and use components of the host cell to make copies of itself. Often, a virus ends up killing the host cell in the process, causing damage to the host organism. Well-known examples of viruses causing human disease include AIDS, COVID-19, measles and smallpox.
