Is entero virus beneficial or harmful?

Enteroviruses are primarily considered harmful as they can cause a range of illnesses, from mild respiratory infections to more severe conditions like viral meningitis and hand, foot, and mouth disease. While they play a role in the ecosystem of human viruses and have been used in some research contexts, their pathogenic effects typically outweigh any potential benefits. Overall, the impact of enteroviruses is more associated with disease than with any beneficial role.
