The incubation period for rubella is 14 to 21 days, with most people developing a rash between 14 and 17 days after exposure. In most cases rubella is a mild condition, but if you suspect you have the disease you should contact your doctor to have it confirmed.
The risk of congenital infection with Rubella is high in the first trimester (90% before 11 weeks gestation), then declines to 25% at 23-26 weeks, and then rises to 67% after 31 weeks. Infection in the first 11 weeks is uniformly teratogenic however no birth defects occur in infants infected after 16 weeks.
