The purpose of this study was to examine the prevalence of paralytic poliomyelitis before and after lifting the suspension of oral polio vaccination in Kano Nigeria, i.e. from 2001-2007. A total of 620 medical records of patients diagnosed with paralytic poliomyelitis were reviewed using systematic sampling technique. Of the 620 cases seen, there were 360 (58.1%) males and 260 (41.9%) females. Children aged 13-24 months (358; 57.7%) were mostly affected. Children from rural areas had higher percentage of prevalence (52.4%) than those residing in urban areas (47.6%). Incomplete immunized paralytic poliomyelitis patients had higher incidence of occurrence (82%) than those with complete polio immunization schedules (18%). The study revealed that the peak year of polio occurrence in the sample was 2004, which was the period of the ban. However, there was a rapid decrease in wild polio virus transmission in 2006 and 2007, which marked the period after the suspension of oral polio vaccine was lifted. However, since new cases of poliomyelitis are still being reported in some communities in Kano, the study recommended that polio vaccination must be encouraged and ensured in all the villages of Kano State in order to eradicate the virus. Health authorities should also devise intervention strategies to rebuild community confidence on the safety of oral polio vaccine in rural and urban areas.
