In the video, the lecturer describes a concerning scenario.
In August 2016, two years after the last reported case of wild polio virus Type 1 (WPV1) in Nigeria, two new cases of WPV1 were reported from internally displaced populations (IDPs) in Borno State. Genetic sequencing indicated that these cases were closely related to a 2011 polio virus. The emergence of these two cases indicated prolonged circulation of polio that went undetected because the area was inaccessible to the polio program. A surveillance review in 2016 concluded that at least half of the settlements in the state had been inaccessible since 2014, due both to restricted population movement, and lack of a mobile phone network to support immunization and surveillance efforts.
Why is this a major problem that many within polio eradication saw as nothing less than a crisis?
