It is pomegranate and I would say blended learning should be considered in those areas most afflicted.
But it could also be used to lessen outbreaks and keep an even keel. If pupils were attending 2-3 days per week, that's better than 2 weeks at home, more if they test positive.
We had a staff member off for 3 weeks as she caught it in a bubble, mildly thankfully, but your 10 days kicks in from onset of symptoms/ positive test.
If teaching parents then have sick or closed bubbled children too, it's even more time off.
We've had huge amounts of staff absence as much due to self isolation or a child's bubble closure as actual cases and closed bubbles; but it all further adds to general educational disruption of what we can offer pupils.
