What is the main symptom of Rubella?

The main symptom of Rubella is a fever accompanied by a general body rash. Rubella, also known as German measles, is characterized by a distinctive rash that typically begins on the face and spreads to the rest of the body. This rash is often preceded by a mild fever, which can vary in intensity. The characteristic symptoms make it crucial to recognize and diagnose Rubella, especially in the context of preventing its transmission, particularly to vulnerable populations such as pregnant women, as Rubella can cause serious complications for the developing fetus.

The other symptoms listed in the options pertain to different illnesses. Inflamed eyes and intense cough are more indicative of respiratory illnesses or conjunctivitis. Severe itching and small blisters suggest conditions such as chickenpox or shingles, where vesicular rashes are present. Nausea and lightheadedness are common symptoms for a variety of conditions but are not specifically tied to Rubella. Understanding the unique symptoms of Rubella helps in early diagnosis and effective public health measures.
