Antigenic ITD <> Molecular ITD for all serotypes. Cases with discordant ITD results may be counted more than once under "ITD results", ie. as "discordant" and "S" or "W", depending on the results of sequencing.
S - Sabin; W - Wild 3
Pending ITD = Pending Antigenic ITD and/or Pending Molecular ITD Total Pending Cases = Pending ITD + Pending Sequencing 5
Based on year of collection of sample, if available. Otherwise, based on year of receipt at reference laboratory.
