Boston-area's COVID surge continued thru holidays, wastewater shows

Jan 9, 2024


Levels of COVID-19 in the Boston area surged to two-year highs during the recent holidays, according to the region's latest wastewater data.

The last time COVID levels were this high was during the omicron surge from the winter of 2021-2022, according to the most recent update on the Massachusetts Water Resources Authority's COVID wastewater page. The amount of COVID in wastewater is widely used to track how prevalent the virus is regionally.

The data, up to date as of Jan. 3, backs up warnings from the U.S. Centers for Disease Control and Prevention, which has said that COVID and flu infections would likely rise through holiday gatherings, too many unvaccinated people and a new version of the coronavirus that may be spreading more easily.
