Early Warning: COVID-19 Detection in Wastewater Streams

Studies have confirmed that SARS-CoV-2, the virus that causes COVID-19, is present in wastewater streams—up to two weeks in advance of reported medical cases. As the only leading indicator, wastewater analysis can serve as an early warning system to quickly establish the presence of the virus before symptoms emerge in the general population. An expert panel discusses how this data can help identify emerging hot spots and anticipate the potential reemergence of the virus in order to inform public health decisions and guide testing and contact tracing.
