COVID-19 wastewater monitoring is 'in the pipeline,' says N.B.'s top doctor

New Brunswick will "definitely" implement COVID-19 wastewater monitoring, according to the province's chief medical officer of health.

But Dr. Jennifer Russell remains tight-lipped about any details.

"We are in discussion with some external partners.I can't share anything publicly right now, but I can definitely say it's in the works," she said.

"So it's coming. It's in the pipeline. Excuse the pun."

Some provinces have been using wastewater monitoringto project COVID-19 trends since last year, when new cases data became less reliable due to restricted PCRtesting.

Last month, the Public Health Agency of Canada launched a newCOVID-19 wastewater surveillance dashboard to illustrate trends in various jurisdictions, and help citizens make decisions about personal precautions,but New Brunswick is not represented.

In New Brunswick, only the City ofMoncton currently collectswastewater samplesto monitor viral levels as part of a research project at Dalhousie University. The data is sharedwith Public Health.

At the end of April, the Department of Health confirmed to CBCit waslooking into expanding wastewater monitoring in the province to provide a clearer picture of COVID-19 transmission and early detection of COVIDactivity.

"At this time, usability for our own population and sewage system is not as clearly defined as it is for some of the larger cities in Canada," a spokesperson had said.

"As we continue to assess usability and feasibility, additional information may be shared in the future."

Russell declined to say how soon a wastewater monitoringsystem could be in place.

She also declined to say whether New Brunswick is considering a provincewidesystem or just monitoring in some of the larger centres.

"I can't tell you that either. I'm very sorry."

Asked how soon an announcement could be made, Russell said only, "It's coming soon. Stay tuned."

SARS-CoV-2, the virus that causes COVID-19,is shed in the feces of people infected with the virus in a form of genetic material called ribonucleic acid (RNA), which can be found in the wastewater.

This shedding typically beginsfive to seven days before peopledevelop symptoms, which is why results can be used as an early warning trigger.

The wastewater surveillance project at Dalhousie Universityhasbeen testing samples for COVID-19 indicators at the Halifax region'sfourmain wastewater treatment plants, Dalhousie student residences and at multiple other communities and locationssince December 2020.

The research team started detecting Omicronin wastewater last November, for example,weeks before the COVID-19 variant was officially confirmed in Nova Scotia.

New Brunswick also has at least 11 Omicron subvariantsnow, including itsfirst confirmed case ofBA.5.

Two more New Brunswickers have died from COVID-19, and 28 people are hospitalized because of the virus,including three in intensive care, the weekly COVIDWatchreport released Tuesday shows.

The regional health authorities, meanwhile,report having 66 COVID patients. That includes people hospitalizedfor the virus, as well as those who were initially admitted for another reason andlater tested positive.

A total of893 new cases of COVID-19 have been reported in New Brunswick, including 533 confirmed through 2,864 PCR lab tests, and 360 from people self-reporting their positive rapid test results.

There are 52.6 per cent of eligible New Brunswickersnow boosted, 88.1 per cent have received two doses of COVID-19 vaccine,and 93.2 per cent have received one dose.
