“…The sporadic isolation of Sabin types 1 and 3 throughout the study period is consistent with the fact that Sabin 1 and Sabin 3 are still being used in routine immunization in Cameroon. In accordance with resent updates on the progress towards PV eradication [4, 21], no WPV isolate was identified during this study in Cameroon, thus suggesting the absence of silent WPV transmission in Yaoundé and Douala between January 2016 and December 2017.…”

Objective Transmission of wild polioviruses (WPVs) and vaccine-derived polioviruses (VDPVs) have been interrupted in Cameroon since July 2014. Subsequently, Cameroon withdrew Sabin type 2 from routine immunization in April 2016. This study aimed to investigate the detection rates and overtime distribution of the types of PVs recovered from urban sewage in Cameroon. Results From January 2016 to December 2017, 517 sewage specimens originating from Yaounde (325 specimens) and Douala (192 specimens) were analyzed. No WPVs and VDPVs were isolated in this study. In contrast, vaccine strains of poliovirus were detected throughout the study period. Isolates Sabin types 1 and 3 were sporadically detected whereas Sabin 2 was found only from January to May 2016 both in Yaounde and Douala. The absence of Sabin 2 in sewage specimens since June 2016 indicates its rapid disappearance after withdrawal from routine immunization in April 2016. This study provides substantial support to the observation that WPV and VDPVs have been successfully eliminated in Cameroon. However, it remains essential to maintain and extend high quality environmental surveillance as long as WPV reservoirs and VDPV outbreaks are detected in Africa.

“…After the emergence of multiple cVDPV2 outbreaks during the preceding 15 years, in April 2016, all OPV-using countries switched from using trivalent OPV (tOPV; Sabin types 1, 2, and 3) to bivalent OPV (bOPV; Sabin types 1 and 3). To control and prevent cVDPV2 outbreaks, approximately 100 million doses of monovalent type 2 OPV (mOPV2) have been distributed in 11 countries ( 4 ). To maintain protection from poliovirus type 2 paralysis, 176 OPV-using countries have introduced at least 1 dose of injectable inactivated polio vaccine beginning in 2015.…”

“…Having researched into the epidemiological trend of poliovirus in Nigeria (2009-2013), Adetokunboh asserted that Nigeria on the road towards total elimination of poliovirus with the reduction in new cases in the last two years. However, more effort is needed to sustain this drive in Nigeria and the other endemic countries [11]. As at September 25, 2015, the World Health Organization (WHO that polio is no longer endemic in Nigeria, leaving the devastating disease endemic in only two countries and bringing the world one major step closer to achieving this goal of ending polio for good [12].…”

Immunization regarding polio has yielded quite a tremendous positive impact as a result of campaigns and involvement of various stake holders from the grass root to the federal level in Nigeria. Interventions from international agencies and organizations in light of synergic partnership with Nigeria in order to tackle polio cannot be overemphasized. All these have helped to place Nigeria as one of the polio -free nations in the world.This was retrospective case study involving a 2 year old female orphan who was moved from a hygiene and sanitationdeficient and non-immune susceptible settlement fulani settlement in Kubau LGA to Anguwan Alkali community in Zaria in order to live with her grandmother. She was taken to Babban Dodo PHC in Zaria for community management of acute malnutrition programme as a malnourished child. The child was claimed to have been vaccinated.
