Enterovirus is a genus of small, non-enveloped RNA viruses that infect humans and animals, often causing mild to severe illnesses such as hand-foot-and-mouth disease or diarrhea. The term combines “enteric” (intestinal) and “virus,” reflecting the gut-tract tropism of many family members. In medical contexts it refers to multiple poliovirus-related pathogens and other enteroviruses detected in clinical samples.
