Article Synopsis
  • Wastewater can help scientists understand public health by showing how germs and viruses are present in communities over time and space.
  • Researchers studied wastewater in Miami Dade County from 2020 to 2022 to track different viruses and bacteria, linking them to COVID-19 cases in hospitals and universities.
  • They found harmful germs and bacteria in the water, showing connections between wastewater, human health, and the use of antibiotics, which can help improve public health decisions in the future.

Article Synopsis
  • - Wastewater-based epidemiology (WBE) is used to monitor COVID-19 infections by detecting SARS-CoV-2 RNA in wastewater, with the effectiveness possibly changing due to virus mutations over time.
  • - This study examined wastewater samples from the University of Miami and Miami-Dade County across different COVID-19 variant periods, comparing RNA levels to clinical COVID-19 cases and hospitalizations.
  • - While correlations were generally strong, they varied by variant; the Omicron period showed a steeper relationship between wastewater RNA levels and case numbers, while the Initial wave had the strongest correlation for hospitalizations.

Clinical testing has been a vital part of the response to and suppression of the COVID-19 pandemic; however, testing imposes significant burdens on a population. College students had to contend with clinical testing while simultaneously dealing with health risks and the academic pressures brought on by quarantines, changes to virtual platforms, and other disruptions to daily life. The objective of this study was to analyze whether wastewater surveillance can be used to decrease the intensity of clinical testing while maintaining reliable measurements of diseases incidence on campus.

The use of wastewater-based surveillance (WBS) for detecting pathogens within communities has been growing since the beginning of the COVID-19 pandemic with early efforts investigating severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) RNA in wastewater. Recent efforts have shed light on the utilization of WBS for alternative targets, such as fungal pathogens, like Candida auris, in efforts to expand the technology to assess non-viral targets. The objective of this study was to extend workflows developed for SARS-CoV-2 quantification to evaluate whether C.

Wastewater, which contains everything from pathogens to pollutants, is a geospatially-and temporally-linked microbial fingerprint of a given population. As a result, it can be leveraged for monitoring multiple dimensions of public health across locales and time. Here, we integrate targeted and bulk RNA sequencing (n=1,419 samples) to track the viral, bacterial, and functional content over geospatially distinct areas within Miami Dade County from 2020-2022.

Background: Firefighters are exposed to a unique set of carcinogens through their work environment that predispose them to several cancers, yet there is limited research related to cancer survivorship amongst this occupational group.

Methods: A mixed-method approach was used to assess cancer survivorship amongst firefighters. Four focus groups and one in-depth interview were conducted with 29 active and retired firefighters who have been diagnosed with cancer to understand the experiences and challenges associated with cancer survivorship in the fire service and desired resources.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in wastewater has been used to track community infections of coronavirus disease-2019 (COVID-19), providing critical information for public health interventions. Since levels in wastewater are dependent upon human inputs, we hypothesize that tracking infections can be improved by normalizing wastewater concentrations against indicators of human waste [Pepper Mild Mottle Virus (PMMoV), β-2 Microglobulin (B2M), and fecal coliform]. In this study, we analyzed SARS-CoV-2 and indicators of human waste in wastewater from two sewersheds of different scales: a University campus and a wastewater treatment plant.
