Covid-Flush Graphic.

Welcome to the SCV2 FLuSHED Study Webpage.

Please feel free to reach out to the FLuSHED study team at or 314-454-8497 or 314-747-4041 with any questions or concerns.

  • SARS-CoV-2 (SCV2) is the virus that causes COVID-19.
  • People infected with SCV2 can spread the virus and shed the virus in their stool whether they have symptoms or not.
  • Wastewater testing detects the SCV2 virus from people with COVID-19 symptoms as well as people without COVID-19 symptoms.
  • This is useful because not all people with COVID-19 see a physician or have a positive test.
  • Wastewater testing allows for early detection of COVID-19 outbreaks in the community.

The SCV2 FLuSHED Study will enroll people who recently tested positive for COVID-19 to determine:

  • How different COVID-19 symptoms and variants affect how much of the virus is shed in stool
  • How previous infections with and/or vaccinations against COVID-19 affect how much of the virus is shed in stool
  • How long people with COVID-19 shed the virus in their stool
