EV71n
EV71n refers to a specific genotype of Enterovirus 71 (EV-A71), a virus belonging to the Enterovirus genus of the Picornaviridae family. Enteroviruses are a group of small, non-enveloped RNA viruses that are commonly found in the gastrointestinal tract of humans. EV-A71 is a significant human pathogen, primarily known for causing hand, foot, and mouth disease (HFMD), a contagious illness that typically affects infants and young children. While HFMD is usually mild and self-limiting, EV-A71 can, in some cases, lead to severe neurological complications such as aseptic meningitis, encephalitis, and even acute flaccid paralysis, which can be fatal.
Genotypes are used to classify strains of a virus based on genetic differences, particularly in their surface
