1.What is E.R. E.R. is an acute febrile rash disease caused by human herpes virus type 6 or 7 infection, characterized by a sudden drop in body temperature after 3-5 days of fever, followed by a rose-red macular rash on the skin, the so-called “fever withdrawal rash”. 2. How do I know if my child has an emergency rash? The rash is usually found in children within 2 years of age, especially within 1 year of age. Apart from fever, the child usually has no other symptoms, good mental state, good appetite, some children may have mild runny nose and diarrhea, but the early stage of the rash is usually high fever, and the temperature is easy to repeat. 3, the child has been feverish for several days, how come the rash has not yet appeared? Children with acute childhood rash usually have a high fever for 3-5 days, and then their body temperature suddenly drops and a rash appears. However, each child’s rash does not appear at the same time, and not every child will have a rash, so there is no need to worry about the rash, as long as the body temperature is stable and the child is still in good spirits, it means that it is almost cured. 4.What does a toddler rash look like? The rash is a rose-red maculopapular rash, which is a small, rice-like rash. It is usually found on the face, trunk, and all parts of the body, and rarely fuses. The rash period is 1-2 days, and then gradually fades. 5.Does the rash mean that the disease is improving? Yes. If the temperature is stable, there are no other symptoms, and the mental state is good, it means that the disease is gradually improving, but many children have repeated infections or combined with other diseases during this period and need to continue treatment. 6.Does the rash make the child uncomfortable? How can I take care of them? Unlike herpes and urticaria, the rash is usually not painful and itchy, so many parents ask how to take care of it. Can I take a bath? Can I blow on the air conditioner? The answer is yes, just be careful not to get cold and heavy feeling again. 7, how to treat emergency rash in children? The main thing is symptomatic treatment, correct and reasonable fever reduction, attention to rest, water and energy supplementation, no indications, do not use antibiotics, and patience is waiting.
