At first you should know that the immune system is composed of cells and antibodies and its basic job is protect the body from harmful microbes when entering these microbes to the body so the natural immune system must differentiate between what is the enemy and what is a friend. The case of the children's immunity Deficiency is one of the situations which make their immune imbalanced.
The child, who suffers from a lack of functional immune system is more
exposed to microbial infection and hard to control the normal remedies. For
example, as the infection bacterial blood poisoning or inflammation of the bone
twice more. As well as microbial infections at unusual places such as abscesses
in the liver or brain or recurrent abscesses of the skin or infection unusual
microbes such as some fungi.
If inflammation occurred by ordinary microbes which infecting all
children, but are highly serious unusual, rather than lead to a sore the
children's throat or furuncle at the skin, they could caused chronic diarrhea
or serious pneumonia which may require hospital treatment.
It is essential to keep in mind that not all
children suffer from frequent infections, will be infected with dysfunction in
the immune system, but there are natural causes for repeated infections and are
the most pervasive from immune lack diseases.
For example, the early going to the
kindergartens before maturation of the children's immunity system before the
age of 4 years, that will lead to the spread of viruses and microbes among
infants and children, especially if the mother is working and she have to send
her children to nursery, and he was
patient, he will spread the infection to his peers, and then they transferred
it to him after curing again.
Also the infection spreads because of poor ventilation in
homes, classrooms and school buses usually due to unhealthy, with some people
closes the bus windows for fear of the cold and but as children gather inside
the bus moves the bad ventilation
microbes among them.
