Diseases of an infectious nature.

that arise in hospitals are nosocoial (nosocomial infections)

In infectious hospitals, compliance with the sanitary-anti-epidemic regime provides for the distribution of patients by nosological forms in the boxes, ongoing and final disinfection, and microbiological control.

Etiology: the main causative agents of nosocomial infections are conditionally pathogenic microbes. Causes:

1) objective, independent of medical personnel;

2) subjective. 1. Objective:

a) hospitals, departments that do not meet the requirements; b) the lack of effective methods of treatment of staphylococcal carriage and conditions for hospitalization; c) insufficient number of bacteriological laboratories; d) unreasonably widespread use of antibiotics; e) many antibiotic-resistant microorganisms; e) an increase in persons with reduced immunity.

2. Subjective:

a) insufficient prophylactically directed activities of medical personnel; b) the lack of a unified epidemiological approach to the study of nosocomial infections; c) lack of proper control on the part of employees of the centers of state sanitary and epidemiological surveillance; d) the lack of reliable sterilization of certain types of equipment; e) an increase in the number of contacts between patients; e) lack of full accounting for nosocomial infections; g) low quality of sterilization of medical instruments and disinfection; h) imperfect system of visits by relatives.


Sources of infection:

1) medical personnel, visitors suffering from infectious diseases (flu, diarrhea, pustules);

2) patients with erased forms;

3) patients with clean wounds who are carriers of virulent staphylococcal strains;

4) infants with pneumonia, otitis media, influenza, secreting pathogenic strains of E. coli.

II. Transmission mechanisms: airborne droplets, fecal-no-oral, contact-household, parenteral (hepatitis B, C, delta, HIV) is possible.

Predisposing factors:

1) weakening of the patient;

2) the length of hospital stay (70% of nosocomial infections in patients lying more than 20 days);

3) excessive use of AB, they alter the intestinal biocenosis, reduce immunological resistance;

4) the hospitalization of a large number of elderly people, chronic patients who are a source of nosocomial infections;

5) hospitalization of young children, especially up to 1 year;

6) large crowding of patients in a hospital.

Diseases of an infectious nature.

    The emergence and spread of various microbial diseases is due to the fact that some microbes under certain conditions can acquire the properties of pathogens. These are the so-called pathogenic microorganisms. Pathogenic microorganisms can cause various diseases, including infectious ones. It is known that pathogenic microorganisms are characterized by strict specificity, i.e.

    Clinical characteristics of infectious diseases in children Infectious diseases in children are one of the frequent reasons for seeking emergency care. In these conditions, in addition to providing assistance, you have to decide on the need for hospitalization. Absolute indications for hospitalization of children in the presence of infectious diseases: 1) all infectious diseases in newborns; 2) all
  3. Infectious diseases
    Description of the most common infectious diseases and precautions against transmission. I. Infectious diseases and infection control: A. Routes of transmission: 1. Direct contact. 2. Contact with contaminated materials (napkins, towels). 3. By airborne droplets (that is, by sneezing). 4. Bites (animal, insect, human). 5. Injections with needles / sharp
  4. Acute infectious diseases
    Emergency conditions for acute infectious diseases are associated with the development or threat of developing toxic toxic shock, hypovolemic shock, acute respiratory failure, multiple organ failure and exacerbation of the course of concomitant diseases. At the prehospital stage, patients with meningococcal infection, acute

  6. Infectious diseases
    Infectious diseases include viral and bacterial infections, diseases caused by microorganisms not related to viruses or bacteria (chlamydia, mycoplasma, rickettsia, etc.), as well as fungal infections (mycoses). Dermatomycoses, characterized mainly by skin lesions, we have already considered in the section "Dermatophytosis", while in this section there were mycoses, manifesting

  8. Food Infectious Diseases
    Microorganisms that cause human diseases are called pathogenic or pathogenic. An infectious disease is a process that occurs in the human body when pathogenic microorganisms enter it. Infectious diseases are diseases characterized by special signs, they are contagious, i.e. able to be transmitted from sick to healthy. Source
  9. Infectious bone diseases
    Among the infectious diseases of the bones, the main place is osteomyelitis - inflammation of the bone marrow and other bone elements. In 80-90% of cases, children fall ill, mainly boys. Men get sick more often than women. Osteomyelitis can develop in any bones, including in the vertebral bodies and in the bones of the facial skull, but proximal and distal metaepiphyses of the femoral and
  10. Infectious diseases. Introduction
    The idea of ​​the infectiousness of diseases such as plague, cholera, smallpox and many others, as well as the assumption of the living nature of the infectious principle transmitted from the sick to healthy, existed among ancient peoples. The plague epidemic of 1347-1352, known in history as the "black death", further strengthened this view. Contact distribution was particularly noteworthy.
  11. Classification of Infectious Diseases
    The causative agents of infectious diseases, as we saw above, are transmitted from patients to healthy people in various ways, that is, each infection is characterized by a certain transmission mechanism. The transmission mechanism of infection was put by L. V. Gromashevsky as the basis for the classification of infectious diseases. According to the classification of L. V. Gromashevsky, infectious diseases are divided into four groups. I. Intestinal infections. The main
  12. General requirements for the prevention of infectious diseases.
    In order to prevent the occurrence and spread of infectious diseases, a complex of organizational, engineering, medical, preventive, hygienic and anti-epidemic (related to the elimination of emerging cases of diseases) measures should be carried out. The complex of preventive measures includes: • providing the population with benign drinking water;
  13. Infectious diseases of the nervous system
    Infectious diseases of the nervous system are quite common. They are caused by bacteria, viruses, fungi, protozoa. Neurological disorders can develop as a result of direct penetration of the pathogen into the nervous system (neuroinfection). Sometimes they develop against the background of other diseases. The selectivity of brain damage in neuroinfections is due to the so-called
    In connection with the achievements of medicine, the course of many childhood infectious diseases has now become easier than before, but there are still severe forms of them that require intensive and sometimes emergency treatment. Treatment of children with severe forms of acute infectious diseases is based on the main principles of etiopathogenetic therapy. The effect of treatment depends on the ability to highlight
  15. Question 29. Prevention of infectious diseases
    Infectious diseases are a group of diseases caused by the penetration of pathogenic (pathogenic) microorganisms into the body. In order for a pathogenic microbe to cause an infectious disease, it must have virulence (poisonous; Lat. Virus - poison), that is, the ability to overcome the body's resistance and exhibit toxic effects. Some pathogenic agents cause
  16. Herbal medicine for infectious diseases
    Infectious processes in the body most often have manifestations in the form of an inflammatory reaction and fever. Inflammation is the most important protective-adaptive, in the biological sense, expedient reaction, due to which the localization of the infectious focus from the body and the destruction of the pathogen at the site of its penetration occur. However, with an insufficient ability of the body to self-defense, inflammation
  17. Infectious and inflammatory diseases of the urinary system
    The group of infectious and inflammatory diseases of the urinary system is the most frequent and studied among the nephropathies that occur in newborns and young children. The share of infectious and inflammatory diseases of the urinary system accounts for most of the nosological forms of nephropathy in childhood. Difficulties in determining the localization of the pathological process, especially in newborns
  18. The concept of colds
    Both the common cold and the flu (as a typical cold-infectious disease) cause viruses. At present, more than 200 types of such viruses belonging to 20 families are already known, and their lists are constantly updated. A cold is caused by viruses belonging to 5 families, while influenza viruses are of three types - A, B and C. Usually, the flu of the last two forms is more calm, and it can be
    As you know, the natural immunity received by the puppy from the mother is lost at the age of 1.5 months and the puppy remains virtually unprotected from the infectious diseases that lie in wait, among which the most dangerous are carnivorous plague, infectious inflammation of the liver (viral hepatitis) and infectious inflammation of the gastrointestinal tract (viral gastroenteritis). Man to these
    An important role in the epidemic process — the emergence and spread of infectious diseases — belongs to social factors. In our country, much attention is paid to measures aimed at the prevention of infectious diseases. Prevention of infectious diseases is a complex of various measures, among which the most important are: • increasing the level of
