It's.... not optimal to have the children miss out on a year of school.
But hey... They did miss that during WW2 too, and proceeded to become the most succesful generation ever.
Personally I find getting corona under control, as it is right now, more important than the missed classes and employers that whine about their workers not being able to work at full productivity because they are covered in children (I mean the latter is the real reason that our government decided to re-open the schools, while being advised against it by the medical advisors).
Our schools and daycare centers never fully closed to be fair. They did *close*, but with exceptions for children of parents that work in essential places, like healthcare workers, garbage collectors, cleaners, power plant workers, train ticket controllers, opticians, supermarkets, etc. etc., plus an exception for children that are deemed 'extra vulnerable' by their schools.
For some schools this means they are completely closed, no children in the class. For some schools that means 90% of their pupils still come to school. The rest hovers somewhere in between.
EDIT: in other news, serological research in India shows that about 21.5% of the Indian population has been infected with corona. That's 290 million people. The official number of infected according to the Indian government is 10,8 million.
The research was conducted with a group of 36000 persons above age 10.
Another study shows that children are even more likely to have been infected with corona: of all children up to age 17, more than 25% have anti-bodies in their blood.
Although the number of 290 million sounds extremely high compared to the official government numbers, there are other studies that show even higher percentages.
For example, Thyrocare Technologies says they tested 700000, and found that 55% of the Indian population has already at some point been infected.
