AFP and poliomyelitis: An AFP case must have any three of these to be classified a “hot” case: < 5 years old, < 3 doses of OPV, be clinically compatible (fever at onset, asymmetric paralysis, and rapid progression of paralysis < 3 days), from a high-risk group/area (nomads, refugee camp or a migrant, hard-to-reach due to security), and from a polio free area [2, 20, 26].
