Volunteer for the "chatline" option from your home.I'd advise caution: you're in closer daily contact with people than most. You could transmit to the NHS or bring back from the NHS and transmit to the children then onto parents etc and the whole thing escalates. I know school pupil numbers are generally low (we had 17 in Monday which dwindled rapidly to 6 then two as the week progressed) but we have to do absolutely everything we can to minimise "cross-contamination". But I understand your dilemma. If you know you've already had it, then that's a different matter of course: volunteer away.
