German measles, or rubella, lasts three to seven days, according to Healthline. It begins with a mild fever and swollen lymph nodes on the back of the neck and behind the ears, and a rash develops on the face and spreads to the rest of the body, explains KidsHealth.
Other symptoms, more common in adolescents and adults, include headache, inflammation of the eyes, appetite loss and nausea, notes KidsHealth. Ear infections and brain swelling are possible complications that may present with persistent headache, earache and stiff neck, states Healthline. Babies born to women who contract German measles during pregnancy are subject to birth defects that include deafness, learning problems, growth delays, heart problems and organs that do not work properly.
