Seventy-eight cases of enterovirus infection, including 25 neuroinfections, occurred in Rostov-on-Don, Russia, during May–June 2013. The outbreak was caused by an enterovirus A type 71 (EV-A71) subgenotype C4 lineage that spread to neighboring countries from China ≈3 years earlier. Enterovirus associated neuroinfection may emerge in areas with a preceding background circulation of EV-A71 with apparently asymptomatic infection.
Enterovirus A type 71 (EV-A71; family Picornaviridae, genus Enterovirus, species Enterovirus A) is the most neuropathogenic nonpolio enterovirus in humans. Over the past 30 years, this virus has caused many outbreaks and epidemics of hand, foot and mouth disease (HFMD) with neurologic complications in the Asia-Pacific region and China (1). In Europe, EV-A71 commonly causes asymptomatic infection (24) and is only occasionally associated with severe neuroinfection (3,5). The last epidemics of EV-A71 infection in Europe occurred during 1975–1978 (6,7).
Dr. Akhmadishina is a postdoctoral researcher. In 2013 she completed a PhD thesis on molecular epidemiology and seroepidemiology of EV-A71 in Russia.


This study received core funding from the participating institutions and from a Russian scientific foundation grant (no. 14-15-00619 to A.N.L. and L.V.A.).
