Oh right, because I looked them up as well, and we had far fewer than Germany, Italy or Denmark. Israel (not in Europe though) opened schools rapidly with few measures, had a surge of infections, and advised other nations not to do what they had done.
This concurs with my research @herecomesthsun
Reporting on Israel
"Israel’s advice for other countries?
“They definitely should not do what we have done,” said Eli Waxman, a professor at the Weizmann Institute of Science and chairman of the team advising Israel’s National Security Council on the pandemic. “It was a major failure.”"
"The lesson, experts say, is that even communities that have gotten the spread of the virus under control need to take strict precautions when reopening schools. Smaller classes, mask wearing, keeping desks six feet apart and providing adequate ventilation, they say, are likely to be crucial until a vaccine is available."
None of which is happening in UK schools...
Unlike Israel we don't seem to be monitoring contacts to see how it is spreading out from schools. In this study below two cases in school lead to 260 cases.

"The first case was registered on 26 May and the second on 27 May. The two cases were not epidemiologically linked. Testing of the complete school community revealed 153 students (attack rate: 13.2%) and 25 staff members (attack rate: 16.6%) who were COVID-19 positive. Overall, some 260 persons were infected (students, staff members, relatives and friends)."
In the UK when we get cases like this we are not following up with this sort of analysis.
