New positive cases of COVID-19 decline during February The second wave of COVID-19, which descended on Princeton in November, may have begun to taper off, as the daily number of new cases appears to have declined during the first few days of February. The number of positive cases of COVID-19 peaked at 57 in April, and then declined steadily through the spring and summer. The numbers began to creep up in October, when 21 new cases were reported, according to the New Jersey Department of Health. A sharp jump of 67 new positive cases in November was followed by an increase of 93 new cases in December. The numbers soared to 111 in January, the New Jersey Department of Health statistics showed.
