A severe pediatric infection with a novel enterovirus A71 strain, Thuringia, Germany

Infection by Enterovirus A71 (EV-A71) is an important cause of hand, foot, and mouth disease (HFMD). Outbreaks including severe cases with neurological and cardiopulmonary complications have been reported particularly from Southeast Asia. In Europe, the epidemiology of EV-A71 is not well understood. In summer 2015, a two-year-old girl from Thuringia, Germany, presented with rhombencephalitis/brainstem encephalitis associated with severe neurological and cardiopulmonary complications. EV-A71 was detected in stool and almost the entire viral genome was amplified and sequenced. While the capsid protein VP1-encoding region belongs to the EV-A71 subgenogroup Cl, the 3D polymerase encoding region represents a unique lineage. Thus, the data suggest that the Thuringian EV-A71 sequence likely represents a recombinant. The case underlines the importance of intensified EV-A71 surveillance in Germany and Europe including analysis of full-genome data. (C) 2016 Elsevier B.V. All rights reserved.
