Rubella is a self-limiting disease, and generally, patients do not require treatment and can recover in about two weeks. However, if symptoms are significant and include fever and joint pain, it may be appropriate to consider using some antipyretic and pain-relief medications. Most patients can fully recover in about two weeks without needing hospital treatment, but appropriate isolation measures should be taken. In terms of diet, it is advisable to consume light, easily digestible food and avoid overly spicy and irritating foods. Generally, rest is recommended, and if appetite is poor, it is better to eat small, frequent meals and avoid fatigue.
