COVID positivity rates in parts of New York City are back over 20% as the 5th wave of the pandemic spreads throughout the state, driven by a highly contagious new subvariant.

The rolling seven-day positivity rate in Long Island City now stands at 21.3%, according to the latest data posted by the city. Large swaths of Queens near or top 15% as well, along with Manhattan neighborhoods like the Financial District and Lincoln Square.

Citywide, the transmission rate has risen to levels last seen in late January, up almost 20% in a week and almost 90% in a month.

The city already raised its alert level to “medium” last week, and on Thursday, Health Commissioner Dr. Ashwin Vasan told CNN all options could be on the table — including the return of a mask mandate — if things continue getting worse.
