Question

how is a virus different from other microbes​

Answer 1

Virus tries to kill whereas some other microbes do not intend to kill

Answer 2

Bacteria and viruses are too tiny to be seen by the naked eye, can cause similar symptoms and are often spread in the same way, but that's where the similarities end. Viruses are smaller and are not cells. Unlike bacteria, they need a host such as a human or animal to multiply. Even though they can both make us sick, bacteria and viruses are very different at the biological level. Bacteria are small and single-celled, but they are living organisms that do not depend on a host cell to reproduce. Because of these differences, bacterial and viral infections are treated very differently.
