Adults infected with rubella generally need to rest and eat a light diet. Rubella is a contagious disease and needs to be isolated until 5 days after the rash appears, and most of it is no longer contagious. The clinical symptoms of rubella in adults are relatively mild, usually with a low fever, accompanied by a slight cough, coughing and other symptoms, and some may have diarrhea, so symptomatic support treatment is possible. If there is recurrent high fever or cough and sputum symptoms are obvious, you can use antipyretic and cough and sputum medications appropriately, and also need to be alert to the complications of bronchopneumonia, and need to improve the chest X-ray examination. Some patients may have secondary bacterial infections and may experience an increase in the white blood cell and neutrophil ratio, which requires appropriate antibiotics.
