The installation of several public health innovations has increased progress toward the eradication of poliovirus within Nigeria and its neighboring countries, according to a recent report.

“Nigeria was very close to interrupting transmission of polio and then experienced an upsurge of transmission,” researchers wrote in The Journal of Infectious Diseases. “Transmission in Nigeria has been driven by reservoirs in northern Nigeria, where several states are considered to be at very high risk.”

In the report, the researchers outlined several interventions enacted under Nigeria’s public health innovation plan to halt the transmission of wild poliovirus (WPV). These efforts included:

By the end of 2013, there was a significant decline in reported cases of WPV, the researchers wrote. WPV type 1 prevalence was reduced to 58% compared with 2012, and only six cases were reported in 2014 vs. 53 in 2013. Between 2012 and 2014, the number of genetic clusters for WPV type 1 went from eight to one, and no cases of WPV type 3 were reported since November 2012.

In addition, the researchers wrote that Nigeria’s poliovirus eradication plan also assisted efforts to suppress Ebola in 2014, as the polio partnership provided the experience and flexibility needed to combat the emerging outbreak.

“At the time this supplement was prepared, Nigeria had gone 12 months with no report of WPV and had started using inactivated polio vaccine,” they wrote. “We believe that these public health interventions and other activities will help Nigeria enter a poliovirus-free environment.”- by Taylor Groff
