What causes rubella in children?

Sometimes when a child has health problems, parents will certainly be very worried. However, since children’s bodies are not fully developed and their immunity is relatively low, they will inevitably be troubled by various diseases. Rubella is one of the more common pediatric skin diseases. Once the disease occurs, the child will feel itchy all over the body and want to scratch it with his hands from time to time. So, what causes rubella in children?

What causes rubella in children?

1. Insect bite rash

This condition often occurs in infants and young children with allergic constitutions, and occurs after being bitten by mosquitoes, bedbugs, lice, and mites, mostly on exposed areas of the skin. Small red spots of insect bites can be seen in the center of wheals and rashes, which mostly occur on the extensor side of the limbs. Sometimes the rash can be seen running along the blood vessels. Children feel locally itchy and restless.

2. Infection factors

Whenever you have a cold, fever, viral, bacterial or parasitic infection.

3. Family factors

There is a history of urticaria in relatives.

4. Contact with pets

Such as the fur and secretions of dogs, cats, and birds.

5. Food factors

Such as eating fish, crabs, shrimps, milk, eggs, etc.

6. Exposure to cold, wind or pollen in the spring

A common cause of this is failure to cover the child with clothes in time after giving him a bath, causing him to be stimulated by the cold wind.

7. Drug factors

Such as penicillin, ampicillin, ceftriaxone, antipyretics, vaccinations, etc., some children have negative penicillin skin tests, but develop rashes or wheals during the injection process, which are common cases; or no rash is seen on the 1st to 2nd day of treatment, but rash or wheals appear on the 3rd day, which should also be considered to be drug-induced and should be discontinued immediately, and anti-allergic drugs should be used at the same time.

The child's urticaria appears suddenly and disappears quickly without leaving any trace, but it is easy to recur and may occur several times a day. Urticaria can occur in any part of the body. When the digestive tract is affected, nausea, vomiting, abdominal pain, and diarrhea may occur. It can also cause laryngeal edema, chest tightness, shortness of breath, suffocation, and bronchial asthma. If the lesions invade the kidneys, proteinuria and edema of the hands, feet, and face will occur. These are all very serious manifestations.
