Public Health England guidelines mean that schools have measures in place to tackle any coronavirus cases that may occur within the school. For example, schools were told to keep pupils in class or year-sized 'bubbles'. This allows schools to easily identify those who may need to self-isolate if someone within the bubble tests positive for the virus. Since schools reopened in Leeds, a number of "bubbles" have been collapsed due to positive coronavirus cases. These are the the secondary schools that have been affected as as of Friday, October 8.
