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.
The source of infection is a sick person and an animal, the discharge of which (feces, urine, sputum, etc.) contains pathogenic microbes. In addition to the patient, the carrier may be a source of infection, i.e. a person in whose body there are pathogenic microbes, but he himself remains practically healthy.
Pathogenic microorganisms are transmitted to a healthy person through soil, air, water, objects, food, insects and rodents.
Pathogenic microbes penetrate the human body through the respiratory organs, mouth, skin and in other ways. From the moment microbes enter the human body until the onset of the disease, a certain period of time passes, called the latent or incubation period. The duration of this period is different for different microbes.
In a latent period, microorganisms develop with the formation of toxic substances - toxins that are secreted by microbes and spread throughout the human body. In the fight against pathogenic microbes, the protective forces of a person act, which depend on his general state of health, so the manifestation and duration of the disease are different. Sometimes people are immune to one or another infectious disease. This immunity is called immunity, which is natural (congenital or acquired after an illness) or artificial (created by vaccination). Artificial immunity can be active (occurs after administration of the vaccine) and passive (appears after administration of serum).
Diseases that occur in humans from germs that enter the body with food (or water) are called foodborne infections. Foodborne infectious diseases include acute intestinal infections (typhoid fever, dysentery, cholera, salmonellosis, etc.), which only people suffer from. Some diseases are transmitted to humans from sick animals (tuberculosis, brucellosis, foot and mouth disease, anthrax, etc.). They are called zoonoses.

FOOD INFECTIONS, FOOD POISONINGS AND GREASY
- GENERAL INFORMATION ABOUT INFECTIOUS DISEASES. CONDITIONS OF THE ORIGIN AND DISTRIBUTION OF INFECTIOUS DISEASES, GENERAL PRINCIPLES OF THEIR PREVENTION
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.
- Foodborne diseases and their prevention
Foodborne diseases are diseases caused by food products. They can be of an infectious and non-infectious nature and are divided into three main types: 1 - food infections, 2 - food poisoning (of microbial and non-microbial nature), 3 -

Charles C. J. Carpenter Acute diseases accompanied by diarrhea caused by bacteria, viruses, and protozoa vary from minor bowel dysfunction causing unpleasant sensations to fulminant, life-threatening forms. Due to the fact that the main cause of acute diarrhea in adults is enterotoxigenic Escherichia coli, and in children -
- CLASSIFICATION OF FOOD DISEASES
Foodborne infections are caused by pathogens of tuberculosis, brucellosis, salmonellosis, camel plague, ornithosis, foot and mouth disease and other zooanthroponic diseases. In addition, this group includes pathogens of human diseases (typhoid fever, cholera, dysentery, etc.) that are not found in animals, but are transmitted to people through food. Foodborne infections are caused by microorganisms in combination
- ETHIOLOGICAL STRUCTURE OF FOOD DISEASES OF PEOPLE
Currently, the doctrine of food diseases of people has a certain differential scheme, which is based on the etiology of the disease. If the cause of human poisoning was food containing organic (berries, mushrooms, etc.) or inorganic poisons, then these poisonings are not of microbial etiology and the person undergoes an appropriate course of treatment. If food was the cause of the disease,

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

Contact with contaminated materials (napkins, towels). 3. By airborne droplets (that is, by sneezing). 4. Bites (animal, insect, human). 5. Injections with needles / sharp
- 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

- 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
- GENERAL PRINCIPLES OF PREVENTION OF INFECTIOUS DISEASES
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

Among the infectious diseases of the bones, the main place is osteomyelitis - inflammation of the bone marrow and other elements of the bone. 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
- 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

- 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;
- 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
- HEAVY FORMS OF CHILD INFECTIOUS DISEASES
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
