Technical Updates on Wastewater Surveillance: Moving Forward from Covid-19

The recent Covid-19 pandemic has not only revealed insufficiencies of health system capacity dealing with acute public health emergencies of international concern, but recurring endemic threats that are further exacerbated by accelerated climate change. Since wastewater-based epidemiology is regarded as one of the most cost-effective tools for probing disease outbreaks, investigating epidemiological trends and providing data for actionable analytics and multi-omic epidemiology, its deployment in different resource settings would require greater sharing and deeper collaboration regionally and globally, with a view to reconciling and devising common and comparable standards and methodologies.
