From NJ Patch:
NEW JERSEY — New Jersey had its biggest jump in school coronavirus outbreaks and cases this past week as a new report says the COVID-19 risk keeps rising for teachers and students.
New Jersey had 18 new in-school outbreaks and 103 new cases linked to those outbreaks this past week — a sharp increase over the previous week's totals when four outbreaks and 16 new cases were reported, Gov. Phil Murphy said this week (see county-by-county list below).
Overall, New Jersey schools have had 88 in school outbreaks and 388 cases linked to in-school outbreaks since the school year began.
Plenty of COVVID-19 in NYC schools too. I just don't understand the policy of keeping school buildings open.
