Review of Public Health Responses to Poliovirus Detection in Wastewater
Poliovirus remains a significant global public health threat, with both wild and vaccine-derived strains detected in clinical and environmental samples, even in nations previously declared polio-free. While wastewater and environmental surveillance systems are increasingly effective at revealing silent circulation of the virus, the translation of these scientific findings into concrete public health actions remains ambiguous. This review article, published in The Lancet Public Health, examines existing literature to identify documented instances where the detection of poliovirus in wastewater successfully triggered specific public health responses across various World Health Organization regions. The study aims to clarify the gap between environmental surveillance data and operational health interventions. By analyzing these events, the authors seek to understand how different regions respond to early warning signs provided by wastewater monitoring. This analysis is crucial for improving global preparedness and response strategies against potential polio outbreaks, ensuring that silent circulation detected in sewage systems leads to timely and effective mitigation efforts to prevent clinical cases and maintain eradication progress worldwide.
