A sharp drop in clinical testing hasn’t stopped New Castle County from getting a clear picture of Covid-19 in Delaware’s most populous county.

Since the early days of the pandemic, the county has turned to its sewers to identify patterns and predict Covid-positive cases.

Scientists from all over the world began examining wastewater after discovering evidence that coronavirus infection can be found in human feces.

At the start of the pandemic, New Castle County collaborated with Biobots Analytics, a company in Boston, to analyze wastewater for the Covid-19 virus. Later that year, the county teamed up with the University of Delaware’s Center for Environmental and Wastewater Epidemiological Research.

Later the county signed a new contract in an effort to get a deeper understanding of the various feces variations.

Since then, scientists and researchers have spotted trends among the various Covid variants, including the alpha, delta, and omicron versions of the virus.
