BOSTON — The closely monitored Boston-area COVID-19 wastewater data has started falling in the past few days, sending an encouraging signal to local infectious disease experts who are “cautiously optimistic” about this virus drop.
After local wastewater samples spiked more than 100% over the previous two weeks — along with an increase in reported virus cases during the omicron BA.2 variant wave — the most recent update from the wastewater tracker shows the sewage data has taken a downward turn.
The north-of-Boston COVID wastewater average has fallen 13% in the past few days, and the south-of-Boston average has gone down 8%. The sewage data is the earliest sign of future virus cases in the community.
