I learned I had TB on the prenatal exam for my second child and likely contracted it during my pregnancy. My child, now 20, has had some unexplained problems with lymph nodes, is "allergic" to the TB test--I think it is positive--but they say the chest xray is okay. Anyway, he has epilepsy and scoliosis and a heart problem. I'm not saying its related, but don't know if it isn't because I'm not a doctor. I don't know if you can take the meds while you are pregnant, but had they been offered to me and I could safely take them, I would have. I hope my son can be treated someday since we have three positive family members.
I think if it was a problem with my son it was because I was sick with active TB disease when I was pregnant (and didn't know it). By the time they tested me, it was latent so I wasn't a candidate for treatment.
I did finally get treated because I need to go on steroids, so you never know what life holds. I just wish I would have gotten it out of the way when I was younger.
