Diabetes mellitus 01%
What is the incidence of deformities in the various stages of pregnancy?

The Rubella virus interferes with the development of organs in the foetus. Therefore, depending on the time of pregnancy and the organs developing during that time, the type and the chances of deformities developing in the child varies. The risk of deformities developing is as follows:

Time of maternal infection Result
1-2 weeks Harmless
3-11 weeks 100% infected fetus
12 weeks 80% infected fetus
13-14 weeks 54% infected fetus
15-16 weeks 35% infected fetus
23-26 weeks 25% infected fetus
