Final Classicifation Classification Criteria Final Diagnosis
AFP Case Definition:
  • An AFP case is defined as a child less than 15 years of age presenting with recent or sudden onset of floppy paralysis or muscle weakness due to any cause , OR
  • Any person of any age with paralytic illness if poliomyelitis is suspected by a clinician
'HOT' or 'high risk' Case Definition:
  • A case that is considered highly suspected of being polio based or clinical data and with the following presenting characteristics:
    • Less than 5 years of age
    • Less than 3 OPV doses
    • Fever at onset of paralysis
    • Asymmetric paralysis
    • Rapid progression of paralysis (within 3 days); And/or
    • Has been in contact with or living in area with possible or recent Polio virus circulation.
Adequate Stool Definition:
  • Two stool specimen (at least adult thumb size)
  • Collected within 14 days from onset of paralysis
  • With a collection interval of at least 24 hours
Grading/Scoring of Sensory Status, Deep Tendon Reflexes and Motor Status:

A. Sensory status is presented in percentage and categorized as follows:

  • ≤25% = Absent
  • ≥25% but <100% = Reduced
  • 100% = Normal

B. Deep tendon reflexes are presented in (+) symbol and categorized as follows:

  • none or 0 = absent
  • + = reduced
  • ++ = normal
  • +++ with/without clonus = increased or exaggerated

C. Motor Status is presented in fraction and categorized as follows

  • 0/5 = absent or no movement
  • 1/5 to 3/5 = reduced movement (with movement but not against resistance or gravity)
  • 4/5 to 5/5 = normal (movement with full resistance and against gravity)
