Does your child’s primary school notify parents of the class if there has been an incidence of chicken pox? Our school sends out general messages about threadworms and nits, but not, it would seem, chickenpox.
My child’s nursery always did this, as a general warning for parents who might be pregnant or have siblings.
I’m not sure what the norm is about sharing this kind of info in primary schools and interested to hear what other schools do.
