Is E.Coli a virus disease or a bacterial disease?

Answer 1

E. coli is not a disease at all, it is a species of bacteria. E. coli can be found as part of the normal microflora in the human gastrointestinal tract, as most strains are harmless. There are some strains (eg: E. coli 01H57) that are pathogenic and can cause enteritis.

Answer 2

E. coli is a bacterial disease caused by the bacterium Escherichia coli, not a virus. It can cause various gastrointestinal symptoms, ranging from mild to severe, depending on the strain of the bacteria.
