German measles, or rubella, is a highly contagious disease that in children and adults is rarely dangerous. However, for an unimmunised pregnant woman, the results can be catastrophic.

The symptoms of German measles are a pinky-red rash that spreads across the body and limbs; mild fever; swollen glands; and general aches and pains. The disease usually lasts between one and three days and normally passes without incident.

Sadly, if a woman without immunity catches German measles in the first twenty weeks of her pregnancy, her infant may be born with Congenital Rubella Syndrome. This can cause a range of serious health issues for the baby, including deafness; problems with eyesight caused by cataracts; congenital heart disease; damage to organs including brain, liver and lungs; and learning disabilities.

Fortunately, most women are immune to German measles thanks to rubella immunisation programmes, and all newly pregnant women will have their immunity tested through the routine blood tests performed by their midwife.

However, if you are planning on becoming pregnant, it is definitely worth checking your immunity with your GP before you plan to conceive as immunity levels can change. A simple vaccination will ensure that your future pregnancy is protected.
