Question

Why is rubella throughout gestation a threat to fetus?

Answer 1

If occurring throughout gestation rubella is a hazardous disease since the virus crosses the placenta and contaminates fetus. The fetus then builds up congenital rubella, a teratogenic (cause of the malformations) disease. Congenital rubella might be prevented by the vaccination. Doctor should always be consulted before the vaccination.
