Article Synopsis
  • This study is one of the first to use wastewater surveillance to track and estimate community infections of Chlamydia and Syphilis by analyzing bacteria shed in wastewater.
  • The research involved collecting untreated wastewater samples weekly from major interceptors in the Detroit metro area and specific neighborhood sewers, optimizing lab methods for detecting the bacteria responsible for these infections.
  • Findings showed that concentrations of Chlamydia and Syphilis were higher in neighborhood sewers than in interceptors, suggesting that actual infection rates may be underreported compared to existing clinical data.

To monitor COVID-19 through wastewater surveillance, global researchers dedicated significant endeavors and resources to develop and implement diverse RT-qPCR or RT-ddPCR assays targeting different genes of SARS-CoV-2. Effective wastewater surveillance hinges on the appropriate selection of the most suitable assay, especially for resource-constrained regions where scant technical and socioeconomic resources restrict the options for testing with multiple assays. Further research is imperative to evaluate the existing assays through comprehensive comparative analyses.

Article Synopsis
  • Peru struggled significantly with COVID-19, leading to diminished focus on other endemic viral diseases due to health facility reallocation.
  • The One Health approach combines environmental surveillance with clinical testing to detect infectious diseases, emphasizing the need for comprehensive monitoring.
  • A study utilized wastewater samples from Trujillo to identify diverse viruses, confirming the presence of multiple human and zoonotic viruses, including SARS-CoV-2 and others through advanced sequencing methods.
