I will agree that is an interesting observation - Jane/John Does having higher incidence of Spina Bifida Occulta

But Occulta means just that - NOT seen. Oh, there may sometimes be a little "dimple" over the site - usually lumbar, but maybe not, so the only way to confirm is by X-Ray or autopsy.

I doubt traffickers are X-Raying their victims.

This is a neural tube defect that occurs around 3-4 weeks gestation probably before most women know they are pregnant.

Taking folic acid supplement greatly reduces the risk of this defect.

Defect seen 1 in 300,000 births world wide and larger percentage in China, India, Iran, Irish and Welsh ancestry.
