Novel Coronavirus infections were detected at 98% of monitoring stations during the 15-day wastewater tests released by CDC

As wastewater testing does not depend on whether people are aware of novel coronavirus infection, or have no symptoms at all.As such, it is often a community’s earliest warning that a wave of COVID-19 infections is coming.It is estimated that 40% to 80% of Novel Coronavirus infections release viral RNA in their faeces, making waste water and sewage an important opportunity to monitor the spread of the virus.To provide critical information on COVID-19 trends, the CENTERS for Disease Control and Prevention (CDC) has activated the National Wastewater Surveillance System (NEWS), which requires daily Novel Coronavirus monitoring of local public wastewater systems at more than 400 wastewater monitoring stations across the United States.The CDC estimates that it takes five to seven days after a toilet flush to send wastewater data to a wastewater monitoring system, and that samples typically turn positive four to six days before clinical symptoms appear.On Feb. 4, the CDC released wastewater monitoring data from Jan. 17 to Jan. 31 at a press conference.The results showed that over 34,000 wastewater samples representing approximately 53 million Americans were collected by the wastewater monitoring system during these 15 days, with novel coronavirus detection in 98% of the stations in all samples collected.However, 70 percent of the stations showed a decrease in viral load detected in samples compared to two weeks ago, suggesting that new cases in the United States were decreasing.Over the next few weeks, the true power of the wastewater monitoring system will become more apparent as hundreds of monitoring stations submit data, said Dr. Amy Kirby, a SPOKESWOMAN for the CDC. The resulting information will allow public health officials to better understand epidemic trends in their communities.
