Can chlamydia be transmitted from mother to baby?

Yes. After rupture of membranes or with delivery, that's why it's so important to treat this in pregnancy because it can cause eye problems in babies.
Yes but not as VD. An untreated mother who delivers naturally can pass the germ to their baby. It does not cause a genital infection. However, it can cause an aggressive eye infection that shows up rather soon. It could also cause a pneumonia that may show up at 2-4 weeks & could be deadly.
