COVID 19 has mainly spread among educational settings since the start of term.
Public Health England says educational settings were where cases mainly grew over the past few weeks.
Secondary schools had the highest number of specifically Covid-19 confirmed clusters or outbreaks – and primary schools shortly after.
Colleges and universities played a small part in the number of outbreaks.
In England there were a total of 595 outbreaks in educational settings this week, with 252 of which coming from secondary schools, and 216 coming from primary schools.
These figures do not account for every infection, but only where an outbreak of two or more people are declared.
