Why do babies have rashes?

The baby is very vulnerable to harm because his body is not yet fully developed. It is also possible to be infected with some viruses or bacteria, which can cause some diseases. Some babies may develop a rash. This will make parents very worried. At this time, parents should be careful not to let the baby grab with his hands. You can also massage your baby frequently with your fingers to relieve itching symptoms. Let’s find out why babies get rashes.

Generally, before the roseola appears, there is a high fever. After the fever subsides, densely packed small red spots like millet grains will appear on the body, and the baby will make a fuss because he feels uncomfortable. During the period of roseola, mothers should try not to take their babies out.

Note:

When the rash appears, mothers should not scratch it with their nails, but massage it gently with their palms.

Don't go out, stay out of the wind

In medicine, roseola infantum, also known as infantile roseola and fever rash, is an acute rash infectious disease common in infants and young children caused by human herpes virus infection. When the disease occurs, irregular red spots appear on the back, neck and other parts of the body. Mild cold symptoms or persistent high temperature appear within 3-5 days, and a rash appears within 12-24 hours after the fever subsides. For most babies, the symptoms will disappear within 1-3 days and the babies will not feel itchy. Except in special circumstances, they will recover in about a week, so there is no need to worry too much.

Causes of roseola infantum:

The main cause of roseola infantum is human herpes virus infection and low immunity of the baby.

1. Human herpes virus infection

The pathogen of roseola infantum is human herpes simplex virus. Since the human body will develop immunity after being infected with this virus, reinfection rarely occurs. Therefore, the virus is not only spread by sick babies, but more commonly by healthy carriers among parents and family members, and can be transmitted through respiratory droplets. The fetus can obtain antibodies from the mother through the placenta. The antibody positivity rate is 25% at 4 months after birth, 76% at 11 months, 90% at 5 years old, and 98% at 17 years old. Roseola infantum is more common in babies aged 6-18 months and is rare after the age of 3. It occurs more frequently in the spring and autumn rainy seasons, with no gender difference.
