On Tuesday a primary school in the 12th arrondissement closed after a pupil and a teacher tested positive for Covid-19.
Then on Wednesday morning a primary school in the central 4th arrondissement closed after a teacher tested positive for the virus.
All pupils and teachers at the school must now self-isolate for 14 days, and get a test done.
French schools break up for the summer holidays on July 4th, so neither school will now reopen before September.
However authorities are keen to stress that neither school is the centre of a cluster, and the closures are purely precautionary.
Ariel Weil, mayor of the 4th arrondissement, said: “There is no cluster, it's a precautionary measure taken by the ARS (the regional health agency).
“But when you think of all the work that has been done with the school principals and the teachers, with the application of such a tough health protocol, meticulous cleaning of the premises by a private company, so that the school can finally reopen at 100 percent capacity on Monday… It's heartbreaking for all of us.”
French schools reopened on a limited basis on May 11th, with strict rules on class sizes which meant that less than half of pupils returned.
The number of classes reopening gradually increased and then from June 22nd the French government lowered the minimum amount of space needed per pupil and scrapped the maximum class size limit.
Since Monday school has again been compulsory for all pupils, although the education minister says that parents in high-risk groups who choose to keep their children at home will not be fined.
