Viruses and Bacteria are totally different.
I’m going to say that again and again, cos it is really, really important.
Viruses and bacteria are totally different.
Bacteria, unlike viruses, are fully functioning organisms in their own right. They eat and generate energy themselves. They replicate themselves, excrete and do everything else that a cell needs to do to live. Bacteria cause problems in many ways, but mainly through overpopulating an area and stopping the body doing what it wants to do there, and by making chemicals that are toxic to the body’s cells. The body fights them by making immune cells that eat them. This process is quite slow and laborious, so bacteria have more chance to cause big problems and so bacterial infections are often more severe than those caused by viruses.
