German measles also known as rubella is a viral infection that can bring about a red rash in the body. German measles can also bring about fever and swollen lymph nodes. The viral infection can spread through contact with droplets through sneezing or coughing. This is usually a mild viral infection that goes away on its own after a week even with no treatment. However, it can give rise to serious complications in pregnant women, as it can cause congenital rubella syndrome in unborn babies. Congenital rubella syndrome can cause serious birth defects like heart abnormalities, deafness, and brain damage.
