, POLIOMYELITIS (ACUTE FLACCID PARALYSIS)
Definition:
• It is an acute viral infection caused by the polio
virus affecting the CNS and is characterized by fever
,pain in the muscle, paralysis and muscular atrophy.
INCUBATION PERIOD
• The incubation time (to the first signs and
symptoms) ranges from 3 to 35 days, with a more
common span of 6 to 20 days.
• Poliomyelitis virus infects and causes disease in
humans alone.

, TYPES OF POLIOMYELITIS
It is caused by the polio virus types 1,2, and 3
1. Polio virus type 1 (Brunhilde) commonest.
2. Polio virus type 2 (Lansing) List common
3. Polio virus type 3 (Leon) second commonest.
All three are extremely virulent and produce the
same disease symptoms.
 PV1 is the most commonly encountered form, and
the one most closely associated with paralysis.
Individuals who are exposed to the virus, either
through infection or by immunization with polio
vaccine, develop immunity.
