The baby first has a high fever lasting 3 to 4 days, with a temperature between 39 and 40°C. After the fever subsides, a rash rapidly appears around the body, and the rash fades quickly without flaking or pigmentation. This may be followed by mild diarrhea, which may resolve spontaneously. There are flu-like symptoms, but they are not obvious. The spirit and appetite are fine, the throat may be a little red, and the lymph nodes in the neck and occipital area may be palpable but not painful to the touch. The rash does not affect the infant’s health and will not recur after one outbreak. There is no difference between acute rash fever and ordinary fever, which is mainly judged by other symptoms. Blood tests are mostly non-referential (clinical values vary and there are no obvious differentiating items). Acute rash will appear with rose-like papules; the latter is mostly accompanied by cough, runny nose, diarrhea, etc. The onset of acute rash is very rapid, and it is very difficult for parents to ensure that their child gets better and heals if they do not have a medical foundation. Even if it is a common cold or diarrhea, it is dangerous to handle it on your own if you do not have the relevant knowledge. This also tends to delay the condition and miss the best time for treatment. Erysipelas is an acute infectious disease caused by a virus that is usually spread by saliva carried out from the respiratory tract. So it is contagious. If your child is in close contact with a sick child and lacks immunity in his or her body, it is entirely possible for him or her to be infected. Since the incubation period of E.R. is 1 to 2 weeks, your child should be closely observed during this time and if a high fever develops, immediate measures should be taken to temporarily isolate the child so as not to expand the infection. If your child is still well after 2 weeks, it means that he or she is not infected with the E.E. virus. The key to preventing E.E.S. is to avoid contact with children who have E.E.S. It is possible that your child’s first high fever after birth is due to E.E. ESE is an upper respiratory tract infection caused by a virus. It is characterized by a high fever (temperature >38.5 degrees, even up to 40 degrees), which is not accompanied by other obvious respiratory manifestations. After about three days, the temperature drops abruptly and a congested corn rash appears all over the body. The rash disappears after 3 more days without leaving any trace. Antipyretic agents are used during the period of high fever. No medication is needed during the rash and you can take a bath and go out. The rash is a typical viral infection that lasts for about a week. The first three days are dominated by a high fever, with a temperature of 39-40 degrees. During this period, there is often no discomfort other than high fever. After three days, the body temperature gradually returns to normal, while a red rash begins to appear on the face and spreads rapidly throughout the body. The rash will disappear naturally in about 3 days. The whole process does not require special treatment except for fever reduction. The diarrhea is somewhat related to the acute childhood rash. If it gets worse, go to the hospital for examination. If it is not serious, take care of it at home and drink small amounts of water several times. If the temperature exceeds 38.5 degrees, it is recommended to choose antipyretic drugs for symptomatic treatment. Physical cooling methods such as: 1, the whole body warm water swab or bath: the baby’s clothing untied, with warm water (about 37 ℃) towel rubbing the whole body or bath, so that the baby’s skin vascular expansion, the body gas will be dispersed; in addition, the water evaporates from the body surface, will also absorb body heat. Each bath about 10 to 15 minutes, about 4 to 6 hours once; 2, wipe with a cool towel: use a slightly cool towel (about 25 degrees) in the forehead, face wipe; 3, drink more water: help sweat, in addition to water has the function of temperature regulation, can make the body temperature drop and replenish the body’s water loss.
