RUBELLA

Risk of the fetus being affected falls with increasing gestation - over 90% in the first trimester with no fetuses being affected after 20 weeks



The risk of fetal infection increases in the third trimester and after 36 weeks, almost all fetuses will be infected

Rubella Posted by PAUL A.

The explanation and answers given are correct. You should have a list of gongenital infections and know how the risk of the fetus being infected / AFFECTED changes with gestation age. With rubella, most fetuses are INFECTED in the third trimester but they are not AFFECTED. That is, the infection is of no consequence to the fetus.

The information on the website is correct. The risk of the fetus being INFECTED is lowest in mid-pregnancy and increases again in the third trimester. If you would like another source, please see text in High Risk Pregnancy.
