More than a year after the Centers for Disease Control and Prevention established the National Wastewater Monitoring System, the agency additional wastewater data into its Covid-19 data tracker on Friday, providing a quick look at whether levels Coronavirus rising or falling in hundreds of communities across the country.
People infected with coronavirus shed the virus in their stools, and wastewater analysis can help officials estimate how common the virus is in a particular community and what variants are circulating.
And because people with the virus often begin to shed it before they seek care or testing – if they ever do – it could also provide an early warning system for outbreaks. imminent or the circulation of new variants. Some communities Omicron detection in wastewater before any test samples from infected residents showed they had the variant.
Amy Kirby, host for National wastewater monitoring systemsaid at a news conference on Friday.
The CDC, which established the system in September 2020, is currently funding wastewater monitoring in 37 states, four cities and two territories, Dr. Not all of those jurisdictions have begun reporting the data.
The new dashboard, which will be updated daily, provides a color-coded view of how virus levels in wastewater have changed in participating communities over the previous 15 days.
But its coverage is limited, and provides an uneven view of the nation’s wastewater monitoring efforts. Of the 255 locations currently reporting data, many are concentrated in Wisconsin, Missouri and Ohio. More than a dozen states – including Idaho, Louisiana, Mississippi and Montana – reported no data at all.
Dr. Kirby said another 250 locations will be added to the panel over the next few weeks, although not all states will be covered by then.
“The real power of this program will be more apparent in the coming weeks as hundreds of test sites will begin sending data,” she said.
