What kind of rash is it when a child has a low-grade fever?

It is a common skin disease for infants and young children to have rashes during their growth and development. The rashes in infants and young children are caused by viruses in the body. Generally, high fever will easily occur when the rash appears. Low fever is also a manifestation of rash. Roseola infantum is also highly contagious. You should pay more attention to prevention and pay attention to the baby's hygiene.

What is the cause of the rash after the baby has a low fever?

Roseola infantum is caused by human herpesvirus type 6. It is a common acute febrile disease in infants and young children and is not highly contagious. Generally, children under 2 years old are more susceptible to infection and disease, especially babies under 1 year old. The characteristic of the disease is that the fever suddenly subsides after 3 to 5 days of fever, and a rose-red maculopapular rash appears on the body. Therefore, it has a nice name: infantile roseola, which is also called milk rash in traditional Chinese medicine. This disease can occur in all seasons, but winter and spring are the peak seasons. After getting sick, people generally gain lasting immunity and rarely get sick a second time.

The most typical symptoms of roseola infantum are: acute onset, high fever reaching 39-40℃, which lasts for 3-5 days and then drops suddenly, and the spirit also improves. Its biggest feature is that the rash appears after the fever subsides. The rash of infantile exanthema is irregular and appears as small rose spots, which may also merge into one. The rash will disappear if pressed with the hand. The rash first appears on the neck and trunk, and quickly spreads throughout the body, especially on the waist and buttocks. The rash will disappear within 1 to 2 days without leaving any pigmentation spots. Before the rash appears, children will have respiratory or digestive tract symptoms, such as pharyngitis and diarrhea. At the same time, the surrounding lymph nodes will generally enlarge, with the occipital lymph nodes being the most common. They are as big as peas and not tender.

When a baby has roseola, the key is to take good care of the baby during the fever and control the baby's body temperature below 38.5, otherwise the high fever will easily harm the baby's body.

What to do if your baby has a rash after a fever

1. Let the baby rest. The ward should be quiet, the air should be fresh, and the quilt should not be too thick or too much.

2. Keep the skin clean and hygienic, and wipe off the sweat on your child's body frequently to prevent him from catching a cold.

3. Let your child drink more boiled water or fruit juice to facilitate sweating and urination, and promote the excretion of toxins.

4. Eat liquid or semi-liquid food.

5. When the body temperature exceeds 39°C, you can wipe the child's body with warm water or 50% alcohol to prevent convulsions caused by high fever.

6. Appropriate use of antiviral drugs: When the baby starts to develop a rash after the fever subsides, take antiviral drugs such as ribavirin appropriately. 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.

7. Reduce fever promptly when 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 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.
