Schools, crèches, nursing homes and sports centres are all affected. A city official is now guarding the town hall and is stopping visitors.
Health minister Maggie De Block says the measure is excessive: “The mayor should have consulted other burgomasters. Telling people they can’t go to school or to their work is excessive. Not everybody will tell the truth either.”
Some locals support the mayor’s decision. “You can’t be strict enough” said a baker’s assistant.
