Congregate living poses one of the highest risk situations for the transmission of respiratory viruses including SARS-CoV-2. University dormitories exemplify such high-risk settings. We demonstrate the value of using building-level SARS-CoV-2 wastewater surveillance as an early warning system to inform when prevalence testing of all building occupants is warranted.

Article Synopsis
  • Antibiotic-resistant bacteria from hospitals can spread to municipal wastewater treatment plants, which may help in transmitting antibiotic resistance genes.
  • A study found high levels of a specific resistance gene, KPC, in hospital wastewater and early stages of treatment but not in the final treated water.
  • The research highlights the importance of wastewater treatment in reducing the spread of antibiotic resistance and suggests that hospitals are crucial sources for these resistant bacteria, indicating a need for better interventions.

Background: Vaccination is one of the most effective ways to fight the influenza epidemic and the coronavirus disease 2019 (COVID-19) pandemic, which represent a major public issue. The objective was to investigate the adherence of heads of French emergency departments (ED) and nursing departments on a potential vaccination campaign of healthcare workers (HCW) and patients in ED.

Method: In February 2021, ED and nursing department heads were asked to answer a national survey.

Wastewater-based monitoring for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the individual building level could be an efficient, passive means of early detection of new cases in congregate living settings, but this approach has not been validated. Preliminary samples were collected from a hospital and a local municipal wastewater treatment plant. Molecular diagnostic methods were compared side by side to assess feasibility, performance, and sensitivity.
