Mikanatha Page 507, As soon as lab results and when required 60-day follow-up repos are available, the cases are classified at NPSU as polio or non-polio AFP. Cases with inadequate specimens are reexamined at 60-days; if no residual weakness is found, the case is discarded as non-polio AFP. Beyond 60 days after paralysis onset, the likelihood of detecting poliovirus is very low
