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 even be compared with a cold. Immunity after such flu (especially C) is quite stable. Type A viruses are easily mutated, leading to a change in their genetic constitution, therefore, each type of mutated virus, creating immunity, does not protect a person from the huge variety of other types of mutants.
Significant differences are noted between the clinical picture of the course of colds (table).
Symptoms of colds and flu
As the table below shows, the common cold is most often a respiratory disease affecting the nasopharynx, throat, and upper respiratory tract.
Most infectious diseases are characterized by high fever, chills and more serious symptoms, indicating that the whole body is involved in the fight against the disease. The most common colds are rhinitis (runny nose), laryngitis (inflammation of the larynx), pharyngitis (inflammation of the trachea), bronchitis (inflammation of the bronchi).
Influenza, especially type A, is almost always more severe than the common cold. A characteristic and distinguishing feature from the common cold is a sudden onset with high fever and chills. With conventional methods and means of treatment, the common cold goes away in 2–5 days, and a complete restoration of the vital activity of the body takes 1–1.5 weeks. The active phase of the flu usually lasts about a week, but residual effects - weakness, loss of strength, muscle pain, etc. - can persist for another 2-3 weeks.

The concept of colds
- Valeological basis for the prevention of colds and colds
The commonality of many causes and the interconnection of the mechanisms of occurrence and course of both groups of diseases allow us to develop many common approaches to their prevention. In determining such approaches, first of all, it is necessary to clarify the main causes and conditions for the occurrence of the diseases themselves. The main ones can be reduced to the following: 1. Decreased immunity due to hypothermia, weakening
- Valeological principles of behavior in colds and colds-infectious diseases
As already shown above, the diseases under consideration are a consequence of the impact of a number of factors. Under these conditions, the body thus restructures its functioning in order to regain homeostatic characteristics through the mobilization of reserve mechanisms. That is, this means that all changes occurring in it and the observed symptoms are adaptive in nature, and
- Cold-triggering factors
Cold and catarrhal infectious diseases are among the most common among the known groups of diseases in terms of population coverage and the number of days of disability. Most often, the main provoking condition for their occurrence is hypothermia. At the same time, not only violations of thermoregulation mechanisms, but also other

Epidemiology is a medical science that studies the patterns of occurrence and spread of infectious diseases in human society, and develops methods for their prevention and elimination. Even the medicine of the Ancient World used such measures to combat epidemics as removing the sick person from the city, burning things of the sick and dead, attracting those who were ill to care for the sick. In modern
- GENERAL INFORMATION ABOUT INFECTIOUS DISEASES. CONDITIONS OF THE ORIGIN AND DISEASE 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.
- Infectious Disease General Concepts
Infectious diseases - an extensive group of human diseases caused by pathogenic bacteria, viruses, protozoa, etc. Infectious diseases differ from non-communicable diseases in such fundamental ways as: • contagiousness (contagiousness); • specificity of the pathogen; • formation of immunity in the process of disease. Infectious diseases can be transmitted from the patient

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
