[Poliomyelitis in Madagascar (1988-1996): current situation in the World Health eradication program by the year 2000].

Abstract

The number of acute flaccid paralysis (AFP) cases reported to World Health Organization (WHO) decreased from 1988 (48 cases) to 1996 (8 cases), but the real endemic situation of poliomyelitis is unknown. Cases are under or misreported. Very often, notifications are delayed; virological investigations of the etiology could not be performed as well as the environment studies and the immunization ripostes. In 1996, only one AFP case was confirmed by isolation of wild poliovirus. The immunization coverage in children under one by OPV (3 doses) was 73.0% in 1996 from the statistics of the Public Health Services but only 54.7% from randomized studies. The eradication of poliomyelitis by the year 2000 has engaged Madagascar in the disease prevention by improving the immunization coverage within the Expanded Immunization Programme in association with the Organization of National Immunization Days in October and November 1997. Likewise, the Virological Unit of the Pasteur Institute was recognized as the National WHO Reference Centre for Polio.
