NEW YORK, Jan. 2 (Xinhua) -- New York City's COVID-19 test positivity rate on a seven-day average went down to 9.39 percent, compared with 9.41 percent one day earlier, Mayor Bill de Blasio tweeted on Saturday.
The rate topped 3 percent late November, which was believed by the city government to signify the arrival of a second wave of the coronavirus, and has remained above the level ever since.
