Anybody know the death rate for rubella in pregnancy?

Hard to know. Rubella during pregnancy is known to cause miscarriage, or fetal deaths but the numbers are hard to come by.It can be a mild flu like illness in mom that triggers an early miscarriage & is never recognized.Birth defects in baby approach 85% for infection in the first 12 wks, dropping to ~50% from 12-16 wks. The earlier the infection the worse the general outcome.Sad but preventable by vaccines.
