The kids are going to school. The faculty is so sick that they don't have enough people to run the school.

Honestly, do people think children just exist in isolation? They have older parents at home. They have older teachers in the classroom. Many of them see even older grandparents and relatives frequently, perhaps also at home.
Where do kids go if they get sick? Home, where they are cared for by older parents.
Kids don't just live in isolated bubbles with other kids. It's dishonest to ignore the second-order effects of kids getting sick.
