Enteric cytopathic human orphan viruses are known by what name?

Echoviruses are a subgroup of enteroviruses and are specifically associated with enteric infections. The term "enteric cytopathic human orphan viruses" refers to viruses that cause intestinal disease and were initially considered "orphan" because they did not fit into the classification of known viruses at the time of their discovery. Echoviruses, in particular, have been identified as having significant pathogenic potential, and they can lead to a variety of illnesses, including viral meningitis and gastrointestinal infections.

The association of echoviruses with enteric disease is crucial in the context of microbiology, especially when studying viral pathogenesis and epidemiology. Understanding echoviruses and their classification helps in diagnosing infections and implementing appropriate public health measures. While other virus groups listed in the options also cause gastrointestinal diseases, echoviruses are specifically labeled as "orphan" due to their initial lack of classification, which aligns with the terminology used in the question.
