Acute respiratory diseases areThe definition, which includes infectious diseases of the respiratory tract. But not everything is so simple. "In order to understand what kind of infection, viral or bacterial, has penetrated the child's body, and to find out if the virus infection caused bacterial complications, it is advisable to pass a detailed blood test, that is, with the determination of the blood formula," says Anna Levadnaya, a pediatrician, Ph.D., the author of the book "Doctor_annamama, I have a question: How to preserve the health of the child."A photo: GettyImagesBy analyzing, you will be able to assess the indicators that are responsible for protecting the human body from infection: leukocytes, lymphocytes, plasma cells. In addition, to understand what is happening to the child during illness, parameters such as the level of monocytes and the rate of erythrocyte sedimentation (ESR) will help you. Quite often, standard blood test forms used in state polyclinics indicate norms for adults that differ from norms for children. To understand on them a little that is possible. The forms on which the child indicators are indicated are usually used in private laboratories. But not always there is an opportunity to go there. So, what will the blood test tell about? In children of different ages, the ranges of normal blood counts differ. To evaluate the general blood test before the doctor's visit, the table will help you .- But do not think that I encourage you to self-medicate. In no case! Never put a diagnosis and especially do not decide what medicines to give to a child, without consulting a doctor, - warns Anna Levadnaya.1/5Photo: Eksmo Publishing HousePhoto:Eksmo Publishing HousePhoto: Eksmo Publishing HousePhoto: Eksmo Publishing HousePhoto: Eksmo Publishing HouseA bacterial infection is more characterized by an increase in the number of leukocytes, a decreased or almost unchanged number of lymphocytes, an increase in ESR, initially low, and then an increased level of eosinophils.Why do children get sick more than adults?• Features of immunity (immaturity)• No immunological memory to all transferred viruses and bacteria• Anatomical and functional features of some organs (thymus, adenoids and pharyngeal tonsils, middle ear, etc.)• Insufficient muscle strength to normally remove mucus from the lungs (inability to cough normally)• Tight communication in children's groups• Inability to blow your nose normally• The child is dressed by the mother, he does not feel hypothermia / overheating• Incorrect (excessive) treatment, isolating the child in a closed room when sick, chaining child to bed with cartoons, irrational antibacterial therapy • Increased attention to the child during illnessPhoto: Eksmo Publishing House Read more:
