[ Kuru is caused by eating the brain of an infected human. Cant get it from a placenta. ]
I disagree respectfully, if the newborn had any head trama during delivery ( not that out of question as the skull of the newborn gets compressed during childbirth ). Proteins could leak through the blood brain barrier and end up in the placenta. Granted this risk could be .000001% but it is still there to say nothing with genetically inheredited malformed proteins living outside of the babies brain.
You misunderstand the situation.
For the baby to have kuru, the baby would have had to consume the brain of an infected person. Since unborn babies don’t eat food, the child cannot be infected with this particular disease.
I don’t know if there’s any way for the mother to transfer the disease to her unborn child, but I see no way the mother could get it from the baby.
Until looking this up I was unaware that kuru is a prion disease. I had been assuming it was viral in nature.
Thanks for helping me learn something!
