There are many reasons and risk factors for a decrease in immunity. A transient decrease in immunity is caused by insufficient protein and energy nutrition, a deficiency in the consumption of micronutrients, especially vitamins A, C, E, D, β-carotene, essential trace elements (zinc, iron, selenium, iodine), polyunsaturated fatty acids, the presence of chronic digestive diseases history of infectious diseases, taking antibiotics, exposure to environmental pathological factors, impaired intestinal microflora. Inadequate protein and energy intake are known to reduce antibody synthesis. Deficiency in the diet of polyunsaturated fatty acids, vitamins A, C, β-carotene, zinc is accompanied by disorders in all parts of the immune response. Iodine deficiency reduces the activity of the phagocytic link, components of antioxidant protection (vitamins A, E, zinc, selenium, etc.), adversely affects the functional activity and vital activity of immunocompetent cells. Many acute and chronic diseases negatively affect immunity, which significantly reduces the child’s resistance to infection and other damaging factors. Continue reading
Thanks to routine immunization, we managed to forget about the many incredibly contagious and dangerous diseases. Nevertheless, it’s too early to relax: if group immunity decreases due to refusal of vaccination, terrible epidemics can return, and these are not just words. In 2018, the media anxiously reported frequent cases of measles, or the “childhood plague,” as it is called. In this article of the “Vaccination” special project, we will tell you why measles is dangerous, how to deal with it, and why it is still not defeated.
The invention of vaccines has radically changed the life of mankind. Many diseases that claimed thousands, or even millions of lives annually, are now almost never encountered. In this special project, we not only talk about the history of vaccines, the general principles of their development and the role of vaccine prevention in modern healthcare (the first three articles are devoted to this), but we also talk in detail about each vaccine included in the National vaccination calendar, as well as flu vaccines and human papillomavirus. You will learn about what each of the causative agents of the disease is, what vaccine options exist and how they differ, and we will touch upon the topic of vaccine-related complications and the effectiveness of vaccines.

Acute respiratory viral infections (ARVI) remain the most common diseases in the world, including among the children’s population. In the Russian Federation, acute respiratory viral infections occupy a leading place in the structure of the general incidence rate and account for more than 90% of all infectious diseases. They represent a large group of clinically and morphologically similar acute inflammatory diseases of the respiratory system caused by more than 350 pneumotropic viruses. According to the WHO, every third person suffers at least one case of acute respiratory viral infections during the year. The mortality rate from acute respiratory viral infections and their complications is also high. According to WHO statistics, every year respiratory diseases associated with seasonal flu cause the death of about 650 thousand people. Continue reading
