Eradicating Polio Menace in Nigeria

Abstract

Polio virus is very stable and can remain infectious for relatively long periods in food and water, which are its main route of transmission before it invades the lymph nodes or sometimes enters the bloodstream where it persists to cause viremia. In majority of cases (99%), clinical disease does not result while in minority of cases (1%) enters the central nervous system where it causes paralytic poliomyelitis.
