So I have checked all members of my household now

and the results kinda surprise me. My husband does not have them at all, nor does my older son. My daughter definitely does

and my youngest son might - it's a bit hard to tell with his little tonsils.
The results don't surprise me in terms of possible symptoms - my daughter has sensory and mild autistic symptoms and frequent headaches/tired/etc.
But in terms of how this might be transmitted, I would certainly have assumed my husband would have been the most likely to have crimson crescents too.:innocent1:
