What is "rubella"?

Rubella, also known as German measles, is a contagious viral infection caused by the rubella virus. It typically causes a mild illness with symptoms such as a low-grade fever, rash, sore throat, and swollen glands. The characteristic rash usually begins on the face and then spreads to the rest of the body. Rubella is most dangerous when caught during pregnancy, as it can lead to serious birth defects and complications for the developing baby, known as congenital rubella syndrome. Vaccination is highly effective in preventing rubella and is typically given as part of the measles, mumps, and rubella (MMR) vaccine.
