P35.8: Other congenital viral diseases

The placenta forms in the mother’s womb during pregnancy. The placenta consists of cells from the mother and cells from the unborn child. The umbilical cord connects the child to the placenta. The child is supplied with oxygen and nutrients from the mother's blood via the placenta.

If the mother contracts a virus while pregnant, the virus can pass from the mother to the child via the placenta. The child can also get infected by the mother's virus during birth. If the child contracts a virus, its health may be harmed.
