Does anyone know... If a pregnant woman becomes infected with TB, can the TB cross the placenta? And if so, what damage can it do to the fetus?
I googled "tb + pregnancy" and got these results:
This would apply to a mom w/active TB, NOT
just a + skin test.
Pulmonary TB does not cross the placenta; extra-pulmonary TB (untreated) might cause problems. (I have seen TB cultured from a placenta.) The baby can become infected w/TB via inhalation of infectious droplet nuclei from mom and frequent face-to-face interaction w/her when being fed and cared for. TB infection in babies and small children can have devastating results--rarely seen in this country, but ?don't know current situation in 3rd world countries.
If you're interested, go to the World Health Organization website, and search TB.
