[The movement of wild poliovirus in West Africa: the Malian case].

The objective of this study was to examine the evolution of the movement patterns and trends of the wild poliovirus in Mali through surveillance of acute flaccid paralysis. A retrospective descriptive study was conducted between 1 January 1998 and 31 December 2005 on 1,002 cases of acute flaccid paralysis (AFP) investigated across the country. Reports made to the National Center for Immunization (CNI) of children under 15 years suffering from AFP were included as part of the epidemiological surveillance.
