ProMED describes a report from researchers at the Australian National Enterovirus Reference Laboratory on 5 cases of AFP positive for EV-A71 between Jan-May 2013. The viruses, found in stool samples from ill children, were identified as belonging to the more virulent genogroup, C4a, by VP1 sequencing.
Members of genogroup C4 were described by van der Sanden and colleagues as being restricted to epidemics in the Asian Pacific region.
