Background: Concentrated animal feeding operations emit air pollutants that may affect health. We examined associations of reported hog odor and monitored with physical symptoms lung function in people living within 1.5 miles operations. Methods: Between September 2003 2005, we measured hydrogen sulfide (H2S), endotoxin, particulate matter (PM10, PM2.5, PM2.5–10) for approximately 2-week periods each 16 eastern North Carolina communities. During the same time periods, 101 adults sat outside...
As part of the response to highly pathogenic avian influenza A(H5N1) virus outbreak in U.S. cattle and poultry associated human cases, CDC partners are monitoring A levels detection H5 subtype wastewater. Among 48 states District Columbia that performed testing wastewater during May 12-July 13, 2024, a weekly average 309 sites 38 had sufficient data for analysis, 11 four reported high virus. was conducted at 203 41 states, with detections 24 nine states. For each or level, state local health...
Exposures to environmental phenols and parabens may be harmful, especially in utero. Prior studies have demonstrated high within-person variability of urinary concentrations across pregnancy.We sought measure phenol paraben biomarker for the Norwegian Mother Child Cohort (MoBa) study, assess variability, investigate any possible external or contamination specimens.We collected three spot urine samples at approximately 17, 23, 29 weeks gestation a hospital setting added preservative...
Wastewater monitoring has provided health officials with early warnings for new COVID-19 outbreaks, but to date, no approach been validated distinguish signal (sustained surges) from noise (background variability) in wastewater data alert the need heightened public response. We analyzed 62 wk of 19 sites participating North Carolina Monitoring Network characterize metrics around Delta and Omicron surges. found that identified outbreaks 4 5 d before case (reported on earlier symptom start...
To compare 4 COVID-19 surveillance metrics in a major metropolitan area.
Environmental justice means equal access to a healthful environment for all. In North Carolina, many sources of pollution disproportionately affect low-income communities and color. Clinicians who recognize effects environmental injustices can improve patient care community health. As an example, we present the industrial-scale hog operations in Carolina.
ABSTRACT Wastewater-based epidemiology has expanded as a tool for collecting COVID-19 surveillance data, but there is limited information on the feasibility of this form within decentralized wastewater systems (e.g., septic systems). This study assessed SARS-CoV-2 RNA concentrations in samples from system servicing mobile home park (66 households) and two pumping stations serving similarly sized (71 larger (1,000 neighborhood nearby sewershed over 35 weeks 2020. Also, raw hospital same was...

Abstract Wastewater monitoring has shown promise in providing an early warning for new COVID-19 outbreaks, but to date, no approach been validated reliably distinguish signal from noise wastewater data and thereby alert officials when the show a need heightened public health response. We analyzed 62 weeks of 19 sites participating North Carolina Monitoring Network characterize metrics before around Delta Omicron surges. found that, on average, identified outbreaks four five days case...
Wastewater surveillance emerged during the COVID-19 pandemic as a novel strategy for tracking burden of illness in communities. Previous work has shown that trends wastewater SARS-CoV-2 viral loads correlate well with reported case over longer time periods (i.e., months). We used detrending series to reveal shorter sub-trend patterns weeks) identify leads or lags temporal alignment wastewater/case relationship. Daily incident cases and twice-weekly measured at 20 North Carolina sewersheds...
Environmental justice (EJ) research requires attention to consequences for participants beyond those typically considered by institutional review boards. The imbalance of power between impacted communities and who create regulate pollution creates challenges participation, yet can also benefit involved. Our community-academic partnership designed the Rural Air Pollutants Children's Health (RAPCH) study provide positive impacts while measuring health effects at three low-resource public...
Abstract Background Wastewater monitoring data can be used to estimate disease trends inform public health responses. One commonly estimated metric is the rate of change in pathogen quantity, which typically correlates with clinical surveillance retrospective analyses. However, accuracy estimation approaches has not previously been evaluated. Objectives We assessed performance for estimating rates wastewater loads by generating synthetic time series were known. Each approach was also...
As nights become warmer, hurricanes stronger, and flooding more frequent, the health impacts of climate change on North Carolinians evident. Extreme heat worker productivity in our agricultural industrial sectors is especially threatening to older adults [[1][1]].
