The baby rash, often referred to as “burning rash”, is caused by a viral infection that is transmitted through the respiratory tract, often within the nursery, and is most common in the winter and spring. The age of onset is generally from six months to two years after birth. Emergency rash in babies is characterized by a “fever and rash”. The child suddenly has a high fever, and the temperature may rise to 39 – 41 degrees. Although the child has a high fever, he or she is in good spirits and some may have a mild cough, vomiting and diarrhea. The fever usually lasts for 3–5 days, then the body temperature suddenly drops, and a rash appears when the body temperature drops, i.e., the fever subsides and the rash comes out or the fever subsides. The rash is characterized by small red spots scattered all over the body, more on the trunk and less on the face and below the elbows and knees. The rash comes out within 24 hours and can completely subside after 1 – 2 days. The rash does not leave any traces after it recedes. The rash is accompanied by swollen lymph nodes in the neck, behind the ears, and behind the occiput, but there is no pressure pain, and it continues to gradually subside for several weeks after the fever subsides. Pediatric emergency rash: Also called infantile rose rash, it is a pediatric acute infectious to sudden onset febrile illness caused by a virus. Clinically, the fever withdrawal rash is characteristic. The disease is known as “milk hemp”, “false hemp”, the cause of the disease is due to external wind-heat evil, depressed in the skin, with the blood and Qi fight knots. The epidemiological characteristics: young children’s emergency rash is caused by a virus, which virus, has not been isolated, the disease is mostly epidemic, the patient to 6 to 18 months of age more young children, within 6 months and 2 years of age is rare, occurring throughout the year, to winter, spring, autumn. After the disease, immunity can be consolidated, and re-occurrence is rare. It is an acute rash infection caused by a virus. The virus has not been successfully isolated. It may be spread by airborne droplets. It usually occurs in infants and children under 2 years of age, and is more common in infants aged 6 months to 1 year. The incidence is more frequent in winter and spring. The incubation period is 1 to 2 weeks. The onset of the disease is rapid, with a rapid rise in body temperature above 39-40℃, accompanied by irritability, cough, vomiting, diarrhea and red throat, and convulsions may occur during high fever. The diagnosis can be made based on typical clinical manifestations. The main symptomatic treatment is to use physical cooling and antipyretics for high fever, and sedatives for irritability and convulsions. Symptomatic habits Differentiation: Acute fever for three consecutive days, high fever can lead to 39 to 40 degrees Celsius. The fever usually subsides after three days, and a rash develops. The child is immunized for life. If a child has a sudden onset of fever for the first time after 6 months of age, and there is no runny nose, cough, diarrhea, etc., and the child is still in good spirits and eating well, then most of the cases can be judged as pediatric acute rash. To confirm the diagnosis, a viral culture can be done to detect the HHV-6 virus. Some inexperienced or poorly trained doctors may misdiagnose a red throat as an upper respiratory tract infection, a cold, or tonsillitis when they see it. Pediatric acute rash Human herpes virus type 6 and confirmation of its pathogen. Human herpesvirus type 6 is the sixth type of human herpesvirus newly discovered in 1986. Studies suggest that herpes virus type 6 is widely spread in the population, especially among infants and young children, and can cause fever without rash and diseases such as pneumonia, meningitis, and hepatitis encephalitis, in addition to infantile emergency rash. Measures The disease does not require special measures and usually resolves spontaneously, with very few sequelae. However, during the course of fever, infants and children need to be well hydrated to prevent dehydration. Some physical cooling methods can be used, such as warm baths, sleeping on ice pillows, and applying warm water to foreheads and limbs. If the temperature is not higher than 40 degrees Celsius, there is no need to use medication to cool down. Generally, the drugs used are paracetamol, Tylenol, etc., but not aspirin.
