Notes from the Field: The National Wastewater Surveillance System's Centers of Excellence Contributions to Public Health Action During the Respiratory Virus Season - Four U.S. Jurisdictions, 2022-23.
Diana Valencia et al. MMWR Morb Mortal Wkly Rep 2023 11 (48) 1309-1312

From the article: "NWSS Centers of Excellence have reported correlation between WWS data and clinical surveillance with WWS allowing localized, timely coverage, and in some situations, valuable lead time notification. In Wisconsin, WWS detected increases in influenza and RSV weeks before increases in related emergency department visits were observed. NWSS data, together with clinical surveillance data, have guided jurisdictional partner decisions regarding allocation of resources, deployment of vaccination clinics, updating clinical guidance, and sending respiratory disease notifications and alerts when trends exceed baseline thresholds. During the 2022–23 respiratory disease season, NWSS Centers of Excellence translated WWS data into real-time public health action for multiple respiratory pathogens, highlighting the contribution of WWS in monitoring disease circulation and helping guide public health response.

Wastewater monitoring can anchor global disease surveillance systems.
Aparna Keshaviah et al. Lancet Glob Health 2023 5 (6) e976-e981

To inform the development of global wastewater monitoring systems, we surveyed programmes in 43 countries. Most programmes monitored predominantly urban populations. In high-income countries (HICs), composite sampling at centralised treatment plants was most common, whereas grab sampling from surface waters, open drains, and pit latrines was more typical in low-income and middle-income countries (LMICs). Almost all programmes analysed samples in-country, with an average processing time of 2·3 days in HICs and 4·5 days in LMICs.

As Covid Emergency Ends, Surveillance Shifts to the Sewers
A ANtnes NY Times, May 11, 2023

With other virus tracking efforts winding down, wastewater data is likely to become increasingly important in the months ahead, scientists say. This approach expanded rapidly during the pandemic. The National Wastewater Surveillance System, which the C.D.C. established in late 2020, now includes data from more than 1,400 sampling sites, distributed across 50 states, three territories and 12 tribal communities.

Wasting no time: CDC adapts wastewater surveillance to stay vigilant for emerging threats
A Kirby, CDC, May 2023 Brand

The COVID-19 pandemic made the value of sewage clear. For epidemiologists, CDC’s National Wastewater Surveillance System (NWSS) provides invaluable insights by helping identify community infection trends before they appear in clinical cases. In 2022, NWSS enhanced detection of SARS-CoV-2 and its variants. But perhaps equally critical were efforts to adapt wastewater surveillance for other emerging infectious disease challenges.
