Although it’s spotty and inconsistent in many places, wastewater testing is pointing to a new wave of COVID-19 infections, with as many as one-third of Americans expected to contract the disease by late February.
With pandemic fatigue also in full force, and deaths and hospitalizations well down from peaks in 2021 because of high vaccination and immunity rates, many people are inclined to shrug off the new wave, fueled by the JN.1 variant. But COVID-19 continues to take thousands of lives a month. Older, sicker people need to take particular precautions, experts point out, and everybody should think about the debilitating condition known as long COVID that can strike even young, healthy people and last years.
Wastewater testing indicates the current wave of COVID-19 peaked in late December with 1.9 million daily infections, the highest since the omicron wave of 2021. Some experts want to maintain and expand wastewater surveillance to stay on top of future waves at state and local levels, even as the public has wearied of COVID-19 mitigation efforts.
