Signs a physician may observe Infection causes the body's immune system to produce antibodies to the virus. Finding these antibodies in a blood sample is evidence either of earlier infection or of immunization. The symptoms of German measles are generally so mild that no special treatment is required. Toward the end of this period you become contagious. You remain contagious for about a week after the rash has faded.
Recovery is complete.
The immune system makes chemicals called antibodies that destroy the virus. Afterward you have natural immunity to the disease, that is, your immune system has produced enough antibodies to the virus so that it cannot successfully reinvade your body. Prevention Immunization is effective and readily available. Many states require it of school-age children. A woman who is not demonstrably immune should be immunized before becoming pregnant.
