The school had to close last Friday, just under a week after it opened. The boy’s classmates and teachers and their families are affected by the quarantine. Two kindergarten groups also had to be isolated as a precaution because a sibling of the student was being looked after there. Where the boy was infected is unclear, said a community spokeswoman.
Because the boy’s teacher also tested positive , their contacts and their families also had to be in quarantine. However, it is still unclear whether the infection is a virus mutation.
