Our son age 12 with type1 diabettes has returned to school in September. Today we have been informed the first case of covid has been notified to school, we have been told that the person is not in our sons year and has not had contact with our son. As our son goes to a school with over 1200 pupils and travels by bus. We can not find out if the affected pupil has traveled on our sons bus. We are concerned if we should continue to send our son as the school is stating the school is covid safe ! i also have a heart condition and had to shield previously. Are we been to cautious ?
