Enterovirus B74 associated with hand, foot and mouth disease

Enterovirus 74 (EV-B74) has been associated with cases of acute flaccid paralysis (AFP) but it is not a commonly found enterovirus. In this work, we present the characterization of an EV-B74 detected from the serum sample of a one-year-old boy presenting with signs and symptoms clinically compatible with hand, foot and mouth disease (HFMD). This is the first report of EV-B74 in Brazil.
