We kept schools going right up til lockdown, when Covid was widely spread across the general public
And yet there have not been reports of a high proportion of teachers becoming ill.
In the final two weeks before lockdown school near me were struggling with a skeleton staff as so many were off unwell.
Now, with schools open for key worker chn/ vulnerable kids, only those teachers who are not classed as vulnerable are working so it follows that the least vulnerable are working in school and therefore more likely to only suffer mild symptoms
