Key result
Environmental surveillance is a crucial and sensitive tool that complements acute flaccid paralysis surveillance to monitor and interrupt the re-emergence of wild poliovirus in Africa.
Why the study?
Although global wild poliovirus type 1 cases have decreased, Africa has experienced a re-emergence of the disease.
This article reviews the re-emergence of wild poliovirus type 1 in Africa and highlights the role of environmental surveillance in interrupting transmission.
May inform polio surveillance strategies in Africa; leaves open optimal implementation pending prospective validation.
Although there has been a global reduction in wild poliovirus (WPV) type 1 cases, Africa has experienced a re-emergence of the disease. This article discusses the re-emergence of WPV in Africa, the transmission and pathogenesis of WPV, and the role of environmental surveillance and other strategies used to interrupt all WPV transmission in the region permanently.

Gwinji et al. (2022) conducted a review in Wild poliovirus type 1. Environmental surveillance vs. Acute flaccid paralysis (AFP) surveillance was evaluated. Environmental surveillance is a crucial and sensitive tool that complements acute flaccid paralysis surveillance to monitor and interrupt the re-emergence of wild poliovirus in Africa.
