Natural Focus Secondary

A secondary natural focus is a concept that is used in the field of geological science. It describes one category of natural lesions that is part of the maternal (or main) zone, known as the natural (congenital) focus. The main signs of a secondary focus are its adjacent localization and connection with the maternal (main) focus. The purpose of this work is to study the specifics of a secondary natural focus and the reasons for its formation.

Nature of Natural Hotspots A hotbed is an area in which conditions for transmission of infection exist, such as bodies of water or swamps with nutrient substrates such as forest floor, soil or vegetation. In order for the primary focus to turn into a secondary one, three conditions must coincide:

1. The need for an infectious agent When the primary focus fades or disappears, it loses the ability to support its local population of microbes, which continue to divide and transmit infection between individual animals. Microbial cultures selected as infectious agents often have less stable life cycles. If its reproduction is too short, the microbial population quickly dies and the conditions for the existence of a source of disease transmission disappear. Thus, the duration of the life cycle in a secondary natural focus should be

A secondary natural focus (or subsidiary focus) is a local group of microorganisms that is in contact with the primary focus of infections. Such a focus develops as a result of the action of factors of a secondary nature and most often acts as a complication or continuation of the primary focus.

Secondary foci are those infectious diseases that develop at the site of primary wounds, bedsores, inflammatory processes around bones or in subcutaneous fat. These microfoci can arise from a focus of secondary inflammation that appears during the process of infection, for example, in chronic infectious diseases (tuberculosis, pneumonia, cholera, purulent sinusitis and others).

When a secondary focus is formed, microbes do not come directly from the external environment, since microorganisms always live on the surface of the skin and mucous membranes. An important stage in the formation of a focus is the change in nonspecific factors of the body’s defense, because the penetration of microbes into the body is already prepared and localized by certain defense mechanisms. A person suffering from a secondary chronic disease will suffer doubly, because there will be deficiencies and weakening of existing defense mechanisms, which can lead to an exacerbation of the disease and transmission of infection. Therefore, when choosing the optimal therapy for infectious diseases, to exclude secondary infection, the presence of primary foci and possible sources of its occurrence must be taken into account. The reason for the formation of second infectious foci may be the activation of pathogenic flora infecting tissues and surrounding organs exposed to pathogenic factors. Secondary foci of infectious, wound effects remain a consequence of infection of the first, primary foci, which can be located in any area of ​​the body - on the skin, gums or even internal organs, in closed cavities of the skull, chest, abdominal cavity, urinary tract, etc. With the spread of microorganisms and various environmental conditions (damage, injuries and other negative
