Abstract

Enterovirus-positive samples diagnosed in Marseille (January 2009 to September 2011) were screened for EV71 by real-time RT-PCR. EV71 was detected in three children below the age of 2 years with no history of overseas travel; two of these cases were associated with severe clinical presentation. Viruses demonstrated genetic similarity to other European genogroup C2 strains. Strain MRS/09/3663 complete sequencing revealed 97.6% identity across the entire genome with a 2008 Singapore isolate, without signs of possible recombination events. To our knowledge, this is the first detection of EV71 infection in Marseille, France, that confirms the current circulation of EV71 in France.
