What is the cause of low body temperature after infantile rash?

Roseola infantum, also known as infantile roseola and fever rash, is an acute rash infectious disease common in infants and young children caused by infection with human herpes virus type 6. When the disease occurs, irregular red spots appear on the back, neck and other parts of the body, and its characteristic is "fever subsides and rash appears." The child suddenly develops a high fever, and the temperature can rise to 39-41 degrees. Although the children have a high fever, they are in good spirits and some may have mild symptoms such as coughing, vomiting, and diarrhea. High fever usually lasts for 3-5 days, and then the body temperature suddenly drops and a rash appears when the body temperature drops, that is, the rash appears when the fever subsides or the rash appears when 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 will appear within 24 hours and disappear completely after 1-2 days. The rash disappears without leaving any trace. The rash is accompanied by swollen lymph nodes in the neck, behind the ears, and behind the back of the head, but there is no tenderness. It lasts for several weeks and gradually disappears after the fever subsides. Therefore, it is normal for infants to have low temperatures due to roseola infantum, and the symptoms will disappear in most babies within 1-3 days. The baby will not feel itchy, and will recover in about a week unless in special circumstances, so parents don’t need to be too anxious.

Precautions for infantile rash

1. Don’t worry too much about high fever.

Roseola infantum is common in infants and young children, and it is often the first fever in the baby's life, and it is a high fever. What worries parents the most when roseola infantum occurs is the persistent high fever. Even if antipyretics are taken, the body temperature will rise again in a short time. But parents should note that although the baby has a high fever, his mental state is not too bad and it basically does not affect his play and eating. This is different from other diseases. After contracting roseola infantum, children can gain long-lasting immunity and rarely get the disease a second time.

2. Breastfeeding mothers need to increase the amount of fluid they drink.

If the baby is still breastfeeding, the mother needs to increase the amount of fluid supplementation. When children are sick, they are more dependent on their mother's breastfeeding. Try to feed more milk to improve the baby's immunity. Mothers should be careful not to eat eggs, fish, shrimps, garlic, leeks and other foods in their diet, and try not to eat raw, cold or spicy foods.

3. Strengthen children's ability to resist virus attacks.

Roseola infantum is a mild infectious disease, so in winter and spring, parents can give their children a bag of Isatis root powder every day to enhance their ability to resist viral invasion and prevent diseases.
