Tracking COVID-19 with wastewater

  • Title：Tracking COVID-19 with wastewater
  • Author：David A. Larsen, Krista R. Wigginton
  • Abstract：Understanding the full extent of the COVID-19 pandemic is an ongoing challenge for public-health officials. Any epidemiological indicator has biases and limitations. Diagnostic testing capacity may be insufficient; hospitalizations lag infections by weeks and do not report on people with mild or asymptomatic disease. Experience with other viral diseases has shown that monitoring sewage for traces of a pathogen enables effective surveillance of entire communities, providing a sensitive signal of whether the pathogen is present in the population and whether transmission is increasing or declining. Researchers around the world are now pursuing the same approach for COVID-19 with the hope that wastewater data can supplement current measures of its prevalence. The novel coronavirus, SARS-CoV-2, has already been detected in wastewater.
