Population-level nutritional assessments often rely on self-reported data, which increases the risk of recall bias. Here, we demonstrate that wastewater-based epidemiology can be used for near real-time population dietary assessments. Neighbourhood-level, untreated wastewater samples were collected monthly from within an urban population in the south-western United States from August 2017 to July 2019. Using liquid chromatography-tandem mass spectrometry, we identify recurring seasonal dynamics in phytoestrogen consumption, including dietary changes linked to the winter holiday season. Using 16S ribosomal RNA gene amplicon sequencing, we demonstrated the feasibility of detecting sewage-derived human gut bacterial taxa involved in phytoestrogen metabolism, including Bifidobacterium, Blautia and Romboutsia. Combined metabolomic and genomic wastewater analysis can inform nutritional assessments at population scale, indicating wastewater-based epidemiology as a promising tool for actionable and cost-effective data collection to support public health nutrition.

Wastewater-based epidemiology (WBE) is increasingly used as a complementary tool for monitoring drug use at the population level, providing anonymized, real-time estimates of community drug consumption. Site-specific applications of WBE can identify localized patterns that national or municipal surveys may overlook. This study presents the first comprehensive, site-specific assessment of illicit drug use in South Korea using WBE.

Eight wastewater samples were collected from three sites in State College, Pennsylvania, during June and July 2024. Nineteen were isolated and sequenced. Three isolates were ≤9 SNPs different from human cases deposited in GenBank, highlighting the potential for wastewater-based surveillance to monitor outbreaks.

Following the experience gained during the COVID-19 pandemic, the Belgian Risk Assessment Group (RAG) developed the Respi-Radar in the summer of 2023 to assess the epidemiological situation of respiratory infections and inform public health preparedness and response in Belgium. The Respi-Radar consists of four risk levels (green, yellow, orange and red), which indicate the extent of viral circulation and/or pressure on the healthcare system. Based on these risk levels, authorities can apply adequate measures depending on the epidemiological trends.

Municipal wastewater may serve as a critical community-composite sample for monitoring bacteria excreted by the contributing population, providing insights into public health risks and microbial diversity. The present study emphasizes the integration of DNA (full-length 16S rRNA) methods, untargeted RNA methods, and different bioinformatic protocols to identify potential human bacterial pathogens in wastewater. Results revealed that, DNA surveillance identified roughly 50 % of the sequencing reads were associated with potentially pathogenic bacteria, as compared to RNA surveillance, which identified roughly 33 % of the reads as associated with potential bacterial pathogens.

The lack of centralized sewage treatment in rural areas has led to severe underestimation of pharmaceutical pollution, posing significant risks to aquatic ecosystems and human health. While wastewater-based epidemiology (WBE) is widely used to estimate pharmaceutical consumption in urban settings, its dependence on sewage infrastructure leads to monitoring deficiencies in rural watersheds with direct wastewater discharges into rivers. Here, we pioneer the application of organic-diffusive gradients in thin-films (o-DGT) passive sampling to conduct WBE in a representative rural area of Hunan Province, China, which lacks sewage treatment facilities.
