Rubella looks like, mainly, its rash as well as other clinical manifestations. It can be preceded by fever, which usually lasts for 1-2 days. When the rash appears, it starts on the face and then spreads to the trunk and limbs. Within a day, the rash may cover the entire body. The rash may be red, dotted papules up to 2-3 mm in diameter. The rash is sparse on the distal parts of the limbs and dense on the trunk, and some rashes may be fused into a patch, similar to scarlet fever, because the skin color between two rashes is red, while some rashes are sparse, and the color of the skin between two rashes is normal. The rash usually lasts for three days, so some people call it three-day measles, which is characteristic of rubella rash. It can also be accompanied by localized lymph node enlargement, mainly in the lymph nodes behind the ears, in the occipital region, and in the neck, which are more obviously enlarged. When rubella goes away, there is usually no pigmentation or flaking, which is different from measles.
