In the context of polio eradication, a case of acute flaccid paralysis (AFP) is classified as 'compatible with polio' when:
- A Clinical criteria of residual paralysis at 60 days are met but adequate stool specimens were NOT collected and no other cause was found ✓
- B Two stool specimens collected 24 hours apart show poliovirus by culture
- C A child under 15 has AFP with residual paralysis at 60 days and poliovirus is isolated
- D Any AFP case in a child under 5 years of age
Explanation
In the WHO/NPSP AFP surveillance classification, a case is 'compatible with polio' when residual paralysis is present at 60-day follow-up (meeting the clinical paralysis criterion), but adequate stool specimens (2 specimens collected at least 24 hours apart, within 14 days of onset) were NOT collected, making virological confirmation impossible, and no other cause for AFP is identified. If adequate specimens are collected and poliovirus is isolated, the case is 'confirmed polio.' If specimens are adequate but negative, it may be 'discarded' or other etiology assigned. This classification drives NPSP response.
