CONNECTICUT — Once again, as happened in late October, there's been a dramatic spike in the concentration of coronavirus in wastewater in several areas across the state.

Recent spike in COVID-19 infections coincide with a dramatic increase in the virus being detected in sewage.

Researchers found that when SARS-CoV-2 ribonucleic acid, known as RNA, concentrations spike in municipal sewage, it's a predictor of infection rates.

Friday, Yale scientists posted the latest data that shows alarming spikes in the virus concentration in wastewater from Stamford, Bridgeport, Hartford and New Haven.

"SARS-CoV-2 RNA concentration in primary sludge closely followed the epidemiology curves established by compiled COVID-19 testing data and hospital admissions, but was a leading indicator by seven and three days, respectively," the study reads.
