About This Dashboard
The County of Santa Clara Public Health Department provides an overview of SARS-CoV-2 concentration in wastewater samples collected at wastewater treatment facilities that serve people in Santa Clara County. Four wastewater treatment facilities receive wastewater from designated geographic areas, known as "sewersheds", within Santa Clara County. SARS-CoV-2 is the virus that causes COVID.
For more information on SARS-CoV-2 concentrations in the wastewater, please visit the Santa Clara County SARS-CoV-2 Wastewater Monitoring Dashboard.
A case is considered someone who tests positive for COVID using viral testing performed in a lab. It is reported by the date that a sample was collected for COVID testing. Case information includes cases that are presumed to be reinfections, defined as a positive COVID test more than 90 days after the first positive test. The 7-day rolling average of new cases for one day is the average of the number of cases from the prior 7 days, excluding the most recent 7 days.
Cases are attributed to the individual's associated sewershed.
For more information on COVID cases, please visit the Santa Clara County COVID Cases and Deaths Dashboard.
