Wastewater monitoring is a valuable public health tool that can track variety of markers. The strong correlations between trends in wastewater viral concentrations and county-level COVID-19 case counts point to the ability data represent changes community's disease burden. However, studies are lacking on whether populations sampled through characteristics broader community implications equity. We conducted geospatial analysis examine extent which contributing collected North Carolina Monitoring Network as June 2022 countywide statewide populations. After intersecting sewershed boundary polygons for 38 treatment plants across 18 counties with census block tract polygons, we compared demographics social vulnerability (1) people residing monitored sewersheds populations, (2) sewered residents, regardless inclusion monitoring, unsewered residents. flagged meaningful any differences greater than +/- 5 percentage points or percent (for categorical continuous variables, respectively) noted statistically significant (p < 0.05). found residents within largely resembled most variables analyzed, only few exceptions. also observed when multiple were county, their combined service county population, although individual sometimes differed. When contrasted given more vulnerable suggesting may fill gaps needed improve approach present here be used characterize nationwide ensure implemented manner informs equitable decision-making.

Public health policy impact evaluation is challenging to study because randomized controlled experiments are infeasible conduct, and changes often coincide with non-policy events. Quasi-experiments do not use randomization can provide useful knowledge for causal inference. Here we demonstrate how longitudinal wastewater monitoring of viruses at a small geographic scale may be used in quasi-experimental design evaluate the COVID-19 public policies on spread among university population. We first evaluated correlation between incident, reported cases SARS-CoV-2 RNA concentrations observed over time, likely due testing requirements options. Using difference-in-differences approach, then association levels wastewater. did observe associated most changes. Policy significant change campus included face covering recommendations, indoor gathering bans, routine surveillance availability.

Abstract Aircraft wastewater surveillance has been proposed as a novel approach to monitor the global spread of pathogens. Here we develop computational framework provide actionable information for designing and estimating effectiveness aircraft-based networks (WWSNs). We study respiratory diseases varying transmission potentials find that 10 20 strategically placed sentinel sites can timely situational awareness function effectively an early warning system. The model identifies potential blind spots suggests optimization strategies increase WWSNs while minimizing resource use. Our findings highlight increasing number beyond critical threshold does not proportionately improve capabilities, stressing importance optimization. show through retrospective analyses significantly shorten detection time emerging presented offers realistic analytic analysis at airports.

Starting October 2022, the Boston Public Health Commission implemented a neighborhood-level wastewater-based epidemiology program to inform strategies reduce COVID-19 inequities. We collected samples twice weekly at 11 neighborhood sites, covering approximately 18% of Boston, Massachusetts’s population. Results from program’s first year revealed inequities unobservable in regional wastewater data both between City and greater area neighborhoods. report results neighborhood-specific recommendations resources help residents interpret use our findings.

Context: Monitoring neighborhood-level SARS-CoV-2 wastewater concentrations can help guide public health interventions and provide early warning ahead of lagging COVID-19 clinical indicators. To date, however, U.S. Centers for Disease Control Prevention’s (CDC) National Wastewater Surveillance System (NWSS) has provided methodology solely communicating national state-level “wastewater viral activity levels.” Program: In October 2022, the Boston Public Health Commission (BPHC) began routinely sampling at 11 neighborhood sites to better understand epidemiology inequities across neighborhoods, which vary widely in sociodemographic socioeconomic characteristics. We developed equity-centered methods report interpretable actionable descriptions levels, trends, inequities. Approach Implementation: produce these data visualizations, spanning 2022 December 2023, we followed four general steps: (1) smoothing raw values; (2) classifying current levels; (3) trends; (4) reporting visualizing results. Evaluation: levels corresponded well with lagged hospitalizations deaths over time, “Very High” coinciding winter surges. When citywide were highest lowest points, trends tended be consistent sites. contrast, when moderate, more variable, revealing emphasizing importance Applying CDC/NWSS resulted vastly different neighborhood-specific cut points “High” or “Low,” obscured between systematically underestimated during surge periods neighborhoods morbidity mortality. Discussion: Our offer an approach that other local jurisdictions use monitoring, comparing, obscure perpetuate recommend adopt equity-focused approaches surveillance valid community comparisons.

Abstract Background Wastewater monitoring is a valuable tool to track community-level disease trends. However, the extent which vulnerable populations have been included in statewide wastewater programs remains unstudied. Objectives We conducted geospatial analysis examine (1) representativeness of data collected through North Carolina Monitoring Network as June 2022, and (2) potential generalize unsewered county. Methods After intersecting treatment plant (WWTP) service areas (sewersheds) with census block tract boundaries for 38 WWTPs across 18 counties, we compared demographics social vulnerability people residing sewersheds monitored countywide populations, connected any sewer system—regardless inclusion monitoring—with populations. flagged differences greater than +/-5 percentage points or percent (for categorical continuous variables, respectively) noted were statistically significant (i.e., twice margin error). Results As whole, resembled population on most analyzed, few exceptions. When multiple within county, their combined population, although individually sometimes differed from population. In nine counties had comprehensive sewershed maps, found that sewered residents higher vulnerability, share Hispanics African Americans, lower income, educational attainment residents. Discussion Our results suggest well represents larger community. Ongoing analyses will be needed sites are added removed. The approach present here can used ensure surveillance nationwide implemented manner informs equitable public health decision-making.
