Fever and rash on body

Children's body resistance is very limited, and they are prone to reactions when stimulated. For example, a rash can easily appear when they have a fever. Because there are many types of rashes caused by fever, the most common ones are roseola, roseola infantum, etc. The key is not to just look at the rash, but also to combine other symptoms for diagnosis. So, what are the causes of rashes on the body due to fever? Let’s take a look below.

Babies' immunity and resistance are not as good as adults, and they are more susceptible to diseases. In life, fever and rash are two common sudden symptoms in babies during infancy. These indicate that the baby may have four diseases, which should especially attract the attention of parents.

1. Roseola. Roseola usually occurs in children under three years old. It is a viral infection and is also called "roseola infantum" in outpatient clinics. "Rash appears after the fever subsides" is the main characteristic of roseola infantum.

2. Scarlet fever. The symptoms of scarlet fever are similar to those of a cold or gastroenteritis. It can be transmitted through droplets, usually with fever, sore throat and rash. The rash is in the form of reddish dots that may appear from the neck to the limbs. It feels rough and is prone to occurring in the armpits, neck, groin, etc. The tongue may also develop a so-called strawberry tongue. The rash will appear 1 to 2 days after the fever and will slowly disappear after about 3 days.

3. Measles. Measles is a highly contagious viral disease with the main symptoms of fever, runny nose, cough, conjunctival congestion, Koplik spots on the oral mucosa and red maculopapular rash on the skin; complications such as pneumonia, laryngitis, encephalitis may occur; severe cases can be fatal.

4. Chickenpox. When a baby gets chickenpox, his whole body will show signs of discomfort, such as fever, which will not be too high, about 38℃ ~ 38.5℃; it may be accompanied by cough or diarrhea, poor appetite and spirit; at the same time as the fever or 1 to 2 days after, the child's skin will itch. First, red dots the size of rice grains appear. After a few hours or a day, the small red rashes will turn into blisters the size of soybeans or mung beans, containing liquid and surrounded by red halos. After about 1 to 2 days, the blisters begin to become turbid and sunken. After 3 to 4 days, the blisters dry up and begin to scab over. Babies often have chickenpox on their trunk and less on their limbs, head and face, and may also have complications such as papules and herpes.

What to do if your baby has a fever

Infant fever is the most common disease in pediatrics. When the baby has a fever, parents should do a good job of care:

1. Keep the baby's resting environment quiet, comfortable and humid, ventilate the room regularly, and adults should not smoke.

2. Reduce clothing and bedding. When your baby has a fever, remember not to dress him in too many clothes, cover him with too thick a quilt, or "cover him with sweat", so as not to affect the heat dissipation and cause the body temperature to rise higher. For many young babies, body temperature can be lowered simply by reducing the amount of clothing and bedding.

3. Wipe your body with warm water or take a bath. While paying attention to keeping warm and preventing the baby from catching cold, undress your baby, rub the whole body with a towel in warm water (around 37°C) or take a bath. This can dilate blood vessels in the skin and increase heat dissipation. In addition, when water evaporates from the body surface, some heat will also be lost.

4. Drink more water. Give your baby plenty of water to help sweat and prevent dehydration. Water has the function of regulating temperature, which can lower body temperature and replenish water lost in the baby's body. Taking vitamin C or eating more fruits rich in vitamin C can effectively promote the recovery of your baby's cold.

5. Physical cooling method. Apply a cold towel to your forehead, then soak it in cold water and apply it again after the towel becomes warm. For older children, using cold water bags or ice bags may be more effective. You can also choose to use pediatric fever patches for your baby.

6. Keep bowel movements smooth.
