Description

technical field [0001] The invention relates to the field of treatment of enterovirus infection, in particular to the use of a polypeptide in the preparation of medicines for treating enterovirus infection. Background technique [0002] Enteroviruses (Enteroviruses, EVs) are a class of pathogens that invade and multiply in intestinal cells, which can induce various inflammations in human intestinal epithelial cells. Enteroviruses belong to the genus Enterovirus of the family Picornaviridae, including poliovirus (PV), Echovirus (Echovirus), Coxsackievirus (CVA, CVB), and new enteroviruses, a total of 106 serum type. According to biological and genetic characteristics, it is divided into 4 groups (species) (Kenowles NJ, Hovi T, Hyypia T, et al. Classification and nomenclature of virus: ninth report of the international committee on taxonomy of viruses. San Diego: Elsevier, 2011): Enterovirus A (EV-A) includes 21 serotypes, Enterovirus B (EV-B) includes 60 serotypes, and Ente...
