  1. 1Number of the patients infected with a given serotype detected by any of the methods.
  2. 2No serotype could be determined because of cross reactivity with multiple serotypes in the IMIA or ambiguous results between methods.
  3. NA. not applicable, serotype could not be assessed using the method.
