Remarks:

  1. All enterovirus-positive specimens are subjected to identification of enterovirus type 71, while typing for other enteroviruses is only performed on a sample of the enterovirus-positive respiratory specimens.
  2. Multiple specimens may have been received from the same patient.
  3. Figures are subjected to minor adjustments.
