Wastewater-based epidemiology (WBE) is an effective way of tracking the appearance and spread of SARS-COV-2 lineages through communities. Beginning in early 2021, we implemented a targeted approach to amplify and sequence the receptor binding domain (RBD) of SARS-COV-2 to characterize viral lineages present in sewersheds. Over the course of 2021, we reproducibly detected multiple SARS-COV-2 RBD lineages that have never been observed in patient samples in 9 sewersheds located in 3 states in the USA.

Article Synopsis
  • * Researchers analyzed the receptor binding domain (RBD) of the virus in wastewater from 9 sewersheds across 3 U.S. states, discovering multiple unique lineages with significant mutations, linked to respiratory illness.
  • * Some identified lineages may originate from immunocompromised patients or animal reservoirs, highlighting WBE's potential to monitor and detect emerging variants before they impact public health significantly.

Some patients who have been diagnosed with Barrett's esophagus will develop dysplasia and, in some cases, esophageal carcinoma (strength of recommendation [SOR]: A, based on consistent cohort studies). Endoscopic surveillance is recommended for all patients with Barrett's esophagus as it is superior to other methods for detecting esophageal cancer (SOR: B, based on systematic review). The degree of dysplasia noted on biopsy specimens correlates with the risk of esophageal carcinoma development and should guide the frequency of subsequent evaluations (SOR: B, based on consistent cohort studies).
