Polio outbreaks in the post-COVID-19 pandemic era: causes and solutions

The coronavirus disease 2019 (COVID-19) pandemic has disrupted polio immunization programs worldwide. The consequences of these programs' suspension were not fully presented during the COVID-19 pandemic, as some take time to present in a population. We conducted a narrative review to provide a perspective of current literature on the effect of the COVID-19 pandemic on efforts made for poliomyelitis eradication. An overview of potential risks of polio outbreaks and areas where wild and vaccine-derived polioviruses have been reported will be presented in this review. Decreased vaccination rate, human and financial resources diversion to tackle COVID-19, and polio surveillance suspension during the COVID-19 pandemic contributed to creating an immunity gap and increasing the risk of polio outbreaks in at-risk areas. Approaches for integrating immunization efforts with educating the general population, engaging religious leaders, and solving gender disparities to fill the gap that have been made during the pandemic. The path to control polio should engage different levels of policy-making, and governments of affected countries play crucial roles. Strong interdisciplinary collaboration and dedicated efforts are needed to inform policymakers and encourage the public to follow vaccination programs.
