What is the difference between measles and German measles?

Both measles and German measles (rubella) are viruses. German measles is accompanied by a blotchy red rash. The patient sometimes suffers a slight cold prior to the appearance of the rash. German measles can be dangerous for pregnant women, who have no immunity for the virus. It is called German measles because it was German physicians who first described this disease. Mild upper respiratory affect, high temperature that can last for four days and conjunctivitis are some symptoms of measles.
