BOSTON (WHDH) – Coronavirus levels in wastewater data collected from the Deer Island water treatment plant have been declining after a week-long rise, raising hopes that the Boston area is moving past the top of the omicron rise.
Maximum COVID-19 levels in the wastewater were recorded around New Year’s Eve through the first few days of January, but there has been a significant drop since then, according to recent readings from the Massachusetts Water Resources Authority’s facility.
“COVID-19 throws us a lot of curveballs, but it’s actually reassuring and useful to see it in the wastewater because over time it’s actually been very predictable,” said Dr. Sabrina Assoumou, of Boston Medical Center, to Mayor Michelle Wu in an Instagram interview.
MWRA has plotted the levels of omicron found in wastewater, data that do not depend on people going out for a COVID test, especially in environments where the waiting time for PCR tests is often very long.
“It certainly predicts that the end is near,” said Dr. Shira Doron, from Tufts Medical Center, on the wastewater data.
When the omicron variant was first discovered in South Africa, there was a steep, three-week increase in the level of coronavirus in wastewater followed by a steep drop.
Doctors now say it appears clear that omicron cases in Bay State will decline, as they did in South Africa.
“It’s always good to have a glimmer of hope. The wastewater is encouraging, but it also tells us to be vigilant,” Assoumou added.
The vaccine and the worms remain the best protection against the virus, officials reminded residents.
