Information on wastewater surveillance

Wastewater surveillance has been implmented as complementary tool of clinical surveillance around the world. These data are shared online such as WHO Dashboard, USA Wastewaterscan, Switzerland Wise Dashboard, EU Dashboard, and Sapporo, Japan

The Wastewaterscan is a large wastewater-based epidemiology network that monitors infectious diseases by analyzing sewage samples across multiple sites, primarily in the United States. It is a collaborative project involving academic institutions and public health partners, and it aims to provide early warning signals of disease trends such as COVID-19, influenza, and other respiratory pathogens. WastewaterSCAN makes its data publicly available through online dashboards Wastewaterscan,2020-2024 and Wastewaterscan, 2024-2025, allowing researchers, public health officials, and the general public to access real-time or near-real-time trends in wastewater signals. This open-data approach supports transparency, reproducibility, and broader scientific and public health use of the surveillance results, although Anyone seeking to use the data for a specified purpose is required to contact aboehm@stanford.edu. When the data are used in any format, the following attribution should be made: “These data were collected as part of theWastewaterSCAN/SCAN project, a partnership between Stanford University, Emory University, and Verily funded philanthropically through a gift to Stanford University.”

Publicitly available data

As of June 2026, the U.S. CDC wastewater surveillance program included 1,278 wastewater monitoring sites that had reported data within the previous two months (April 26, 2026 to June 20, 2026). These sites collectively covered an estimated 144 million people, corresponding to approximately 43% of the total U.S. population (Ref).

The CDC wastewater surveillance data are compiled from three major sources:

  1. State and local public health departments (“State_Territory”) These data are collected and reported by state and local health departments and are supported through the Epidemiology and Laboratory Capacity for the Prevention and Control of Emerging Infectious Diseases (ELC) Cooperative Agreement.

  2. CDC’s national wastewater testing contract (“CDC_Verily” and previously “Biobot_Analytics”) These data originate from sites participating in CDC’s national wastewater testing program, which is currently operated by Verily Life Sciences(Visulized data), LLC. Data generated under a previous contract are identified using the “Biobot_Analytics” source designation.

  3. WastewaterSCAN (“WastewaterSCAN”) These data are generated by WastewaterSCAN, a collaboration among Stanford University, Emory University, and Verily. WastewaterSCAN data are provided primarily to support public health decision-making and are distributed under Stanford University’s CC BY-NC 4.0 license.
