Pediatric rubella is a mild eruptive infectious disease, commonly seen in children under five years old.

Rubella is also known as "rubella", Jingui Yaolue refers to it as "urticaria", and "The Complete Book of Pediatric Measles" calls it "rubella".

Eruptive diseases, including measles, rubella, roseola infantum, and scarlet fever, are among the four major pediatric conditions. This section focuses on differentiating pediatric rubella and includes infantile roseola infantum. For others, please refer to the sections on "Pediatric Measles" and "Pediatric Scarlet Fever".

1. Defense aspect pathogenic heat rubella: Initially presents with aversion to wind and fever, generally not high, lasting 1 to 2 days, followed by the appearance of rash points all over the body, first on the head and face, then the trunk, and quickly spreading to the limbs, mostly covering the entire body within a day. The rash is light red, small and sparse, with itching, swollen lymph nodes behind the ears and occipital bone, accompanied by cough, sneezing, runny nose, sore throat, red eyes, etc., thin white tongue coating, red-purple finger veins, and floating rapid pulse.
2. Qi aspect pathogenic heat rubella: Higher fever, bright red rash, denser rash points, thirst, restlessness, dry stool, yellow-red urine, thin yellow tongue coating, strong rapid pulse, red-purple finger veins reaching the qi pass.

1. Defense aspect pathogenic heat rubella: Mainly caused by external contraction of seasonal pathogens, fighting with qi and blood, stagnating in the muscles, and erupting on the skin. Due to the mild pathogen, it generally only affects the defense aspect. The distinguishing symptoms are: rash appears quickly, usually within 1 to 2 days of fever, and fully erupts within 24 hours. The rash is small, sparse red dots, light red in color, resembling sand, first appearing on the head and face, then the trunk, limbs, and finally the whole body, with no rash on the palms and soles. The rash fades in 1 to 2 days in the order of eruption, with itching during eruption, no desquamation or scars after fading, and mild systemic symptoms, with swollen lymph nodes behind the ears.
2. Qi aspect pathogenic heat rubella: Due to intense heat toxin, pathogenic heat transmits to the qi aspect, and symptoms gradually worsen. The distinguishing points are: higher fever, rash color changes from light red to bright red, rash type changes from small and sparse to dense, accompanied by thirst, restlessness, dry stool, short red urine, etc.
3. Treatment principle: Initially, when the pathogen is in the defense aspect, the method should be dispersing wind and releasing the external, clearing heat and removing toxin, with the representative formula being Modified Disinfecting Decoction: If pathogenic heat affects the qi aspect, the method should be clearing heat and removing toxin, assisted by cooling blood, with the representative formula being Eruption-Promoting and Cooling Decoction.

Appendix: Infantile Roseola Infantum

Infantile roseola infantum is an acute exanthematous infectious disease, and the disease-causing mechanism is roughly the same as that of rubella, but the clinical symptoms differ. The key points for symptom differentiation are: (1) Age of onset: The age of onset for children with roseola infantum is younger than that of children with rubella, mostly seen in infants under one year old; (2) Type of rash: The rash of roseola infantum is finer and denser than that of rubella; (3) Color of rash: Rubella presents with a light red color, while roseola infantum presents with a rose color surrounded by a light red halo; (4) During eruption: Rubella is accompanied by itchy skin, whereas roseola infantum is not; (5) Timing of eruption: Rubella shows rash points simultaneously with fever, while roseola infantum shows rash points after the fever subsides; (6) Sequence of eruption: It first appears on the neck, face, trunk, and limbs, with no rash on the palms and soles. The treatment methods are similar to those for rubella.

1. Jingui Yaolue．Water Qi Disease Pulse and Symptom Treatment: "When wind qi interacts, if wind is strong, it results in urticaria."
2. Zhubing Yuanhou Lun．Wind Itching and Hidden Rash: "Children, due to sweating and removing clothes, allow wind to enter the striae and interstice, interacting with qi and blood, forming a connected hidden rash. Wind qi only floats shallowly in the striae and interstice, its force is slight, thus it does not swell or hurt, but forms a hidden rash, causing cutaneous pruritus."
3. Youyou Jicheng．Urticaria Treatment: "Red dots appearing within the skin without emerging belong to the Shaoyin monarch fire, called rash. The symptom appears sparsely on the chest, abdomen, hands, and feet, caused by rootless and uncontrolled fire gathering in the chest, steaming up to the lungs, and hiding in the skin to form small rashes, resembling mosquito bites or flea spots rather than brocade patterns."
4. "Urticaria mostly belongs to the spleen, as it is hidden within the skin, often itchy when it appears, or not red, commonly known as wind dan."
5. 《Complete Book of Pediatric Measles．Difference between True Measles and Roseola Infantum Rubella》: "Roseola infantum, when a child is just born and not yet a month old, red dots appear all over the body, mottled like cinnabar, all caused by the child receiving heat toxin in the mother's womb, thus appearing on the skin after birth, should not be mistaken for seasonal epidemic measles, and decoction should not be used recklessly."
6. "Rubella, also somewhat similar to measles, occurs in children just born, one month, half a year, or one year old, during hot weather, caused by wind-heat. This is not due to fetal toxin, but a minor skin disease caused by wind-heat affecting the spleen and lungs, not classified as true measles."
