What to do if a child has a rash after a fever

Many children will develop a rash on their body after they have a fever. This condition is clinically known as roseola infantum or fever rash, etc., and the disease is caused by a viral infection. It can occur in any season of the year, but the incidence rate is higher in spring and autumn. The incubation period of this disease in children is often about two weeks. So what should I do if a child develops a rash after a fever?

First, what should you do if a child develops a rash on his body after having a fever? Let the baby rest, the ward should be quiet, the air should be fresh, and the quilt should not be too thick or too many. Keep the skin clean and hygienic, and wipe off the sweat on your child's body frequently to prevent him from catching a cold. Let your child drink more boiled water or fruit juice to facilitate sweating and urination, and promote the excretion of toxins. Eat a liquid or semi-liquid diet. When the body temperature exceeds 39℃, you can wipe the child's body with warm water or 50% alcohol to prevent convulsions caused by high fever. Appropriate use of antiviral drugs: When the baby starts to develop a rash after the fever subsides, it is appropriate to use antiviral drugs such as ribavirin. Antibiotic treatment is generally ineffective. In addition, traditional Chinese medicine has a good effect in treating this disease. When the fever first occurs, you can take heat-clearing and detoxifying drugs under the guidance of a doctor. After the rash appears, take some detoxifying and rash-clearing drugs to help excrete pathogens and toxins in the body.

Second, roseola infantum mostly occurs in infants and young children aged 6 to 18 months. The onset of disease is often sudden, and the body temperature rises rapidly, usually between 39°C and 40°C. Severe patients with high fever in the early stages may have convulsions, and some may experience mild runny nose, cough, eyelid swelling, and conjunctivitis. During the fever period, there are symptoms such as poor appetite, nausea, vomiting, mild diarrhea or constipation, as well as congestion in the pharynx and swollen lymph nodes in the neck. After three to five days of fever, the body temperature drops suddenly. After the fever subsides, the child may develop light red macules or maculopapules of varying sizes all over the body, starting from the chest and abdomen and quickly spreading to the whole body. At this time, the child's fever has subsided and he can fall asleep peacefully. This is medically called "fever rash", which is a unique manifestation of roseola infantum.

What should you do if your child develops a rash after having a fever? Cool down the child in time when the fever is high: The main symptom of roseola infantum in the early stage of the disease is high fever, so the focus of treatment is to reduce the fever. Among them, physical cooling is a relatively safe method of reducing fever, but it may be difficult to reduce fever quickly when the body temperature is too high. There are many physical cooling methods. You can apply a towel soaked in cold water to the forehead, or take an alcohol and warm water bath to wipe the child's neck, armpits, elbows, groin and other wrinkled areas to help dissipate heat.
