The child who has just appeared, does not yet have a perfect system of protection against the effects of various antigens. His skin and mucous membranes are not sufficiently developed to prevent the entry of bacteria and viruses into the body. Saving babies from potentially dangerous for them diseases of innate immunity. About his features, and ways to protect the baby in the first months of his life and will be discussed.
Natural congenital immunity
The first thing you have to face antigens penetrating the children's body are local mechanisms of protection. These include:
- skin integument;
- cilia in the nose and in the bronchi;
- gastric juice and enzymes secreted by the digestive tract.
The main functions of local factors of innate immunity are to prevent the foreign antigen from becoming entrapped in the mucosa and penetrating further into the body. If this occurs, humoral immunity, consisting of the presence of biologically active substances, is included. They both destroy or inhibit cells of foreign antigens.
Biologically active substances are the main barrier in the pathway of antigens in newborns. They are produced by salivary, sweat and sebaceous glands.
Features of immunity of newborns are such that local mechanisms of protection are still weak, and biologically active substances do not always perform their functions to the end and changeable antigens can still get into the blood. In newborns, this type of protection in the first months of their life is provided by antibodies that have entered the body during mother's pregnancy.
The main type of disease, in which congenital protection is most effective is ARVI.
To further qualitatively maintain immunity, the child requires a breast-feeding type. Obtaining the necessary antibodies, now through
Is there an innate immunity to chicken pox?
There is an opinion that small children in the period up to three months from the day of birth are resistant to chickenpox due to innate immunity. It is definitely impossible to affirm this, since specialists are still studying this issue.
According to medical experts, most often with congenital immunity to chickenpox they confound the already transferred chickenpox in mild form. To check whether there is a child who obviously does not have chickenpox, immunity to it, you must pass a blood test for the presence of antibodies.
