Many diseases can cause rash in children, among which measles, rubella, acute rash in children, scarlet fever and chickenpox are more common. For the rash caused by these diseases, the commonly used Chinese medicine Baofuling should be distinguished from the following aspects:
General symptoms
Measles has a high fever, and the symptoms of cough and runny nose are obvious. There were many measles spots on the buccal mucosa before eruption. Rubella is generally low in fever, with rare cough and swollen lymph nodes behind the ear and pillow; Children with acute rash have a high fever, and the fever will automatically drop after 2-3 days; Scarlet fever begins with aversion to cold and fever, and the throat is red, swollen and festering, with a "bayberry"-like tongue; Chickenpox generally has mild symptoms and low fever.
Eruption time
Measles rash appears gradually, usually in about 3 days; Rubella erupts quickly, usually within 24 hours; Children's acute rash fever only appears after it subsides, usually within 24 hours; Scarlet fever rash appeared quickly and spread to the whole body within 24 hours. Chickenpox rashes appear in batches and last for a long time.
Rash measles is dark red, rubella is reddish, children's acute rash is rosy, scarlet fever is bright red, chickenpox is reddish at first, and there is blush around the foundation after it becomes a rash.
Outbreak form
Measles rash is slightly raised, with different shapes and sizes, first sparse and then dense, not itchy; Rubella rash is small, sparse and even, with itching feeling; The child's rash is thinner and denser than rubella, and there is no itching. Scarlet fever rashes vary in size, some are finely divided, some are flaky, dense and seamless; Chickenpox starts with a rash the size of a grain of rice, followed by herpes, which is as big as a pea, round or oval and itchy.
Rash distribution
Measles first occurs in the ears, then in the neck, then in the forehead, then in the trunk, limbs, hands and feet. Rubella starts from the face and trunk, hands, feet and heart, without rash; Children's acute rash consists of neck, face, trunk, limbs and hands and feet, and there is no rash; Scarlet fever is difficult to distinguish healthy skin from neck, face, trunk, limbs and whole body, but there is a circle of pallor around lips; Chickenpox distributes centripetally from the head, face, trunk and limbs.
Hand, foot and mouth disease rash
Herpes of hand, foot and mouth disease is also easily confused with other small rashes. Generally, the herpes of hand, foot and mouth disease is just the size of a grain of rice at first, about 1 to 2 mm, bright red, and generally appears in special parts such as palms, soles of feet, oral mucosa and perianal regions. After a long time, it will become a blister, and the rash will be transparent with water inside, but it will not get bigger.
