This story is completely fabricated, developed in the little minds of these disturbed individuals. They really need to spend their time writing fiction/suspense or something, they are apparently quite good at it.
I hope you’re making the ‘common knowledge she had mono’ thing up.
Mono causes zero complications during pregnancy, nor is it a birth defect or miscarriage risk.
Booting or removing children from school because of Mono is an ill-informed relic of the pre 1970’s. The amount of saliva that someone else has to injest to trigger anything more than an immune cell-generating antibody reaction is substantial. It takes a minimum of care to prevent transmission. Care like ‘dont french kiss your sister’.
Are they seriously floating this?
