Difference between infectious and noninfectious diseases

Diseases can be defined as the alterations, to a lesser or greater degree, of the proper functioning of the organism or of some of its parts. This can be caused by different pathogens both internal and external. Similarly, it is a process that travels through living beings when their normal health condition is affected by different reasons or factors either intrinsic or extrinsic.

Diseases can be classified according to the degree to which they occur, according to the possibilities of survival or according to their origin, being in the latter group the infectious and non-infectious diseases.

This article presents the differences that exist between these two types of diseases in order to provide our readers with more information about them and the causative agents, among other details.

An infection or infectious disease is a condition caused by different microbial pathogens that can be viruses, bacteria, fungi, parasites or germs. These diseases require treatment with biological controlling agents of the specific pathogens, otherwise, that pathogen continues to reproduce affecting the body to a greater extent and in many cases can cause death.

Infectious diseases are characterized by high contagious capacity, due to the high propagation capacity of the causative agent, the ability of these agents to settle and multiply in the host organism and the pathogenicity, that is, the capacity to produce diseases.

The main routes of infection are oral-fecal when the person ingests food or drinks contaminated with feces, the respiratory when the person inhales bacteria scattered in the air by another contaminated living being or by direct contact with another infected person. Infectious diseases generally go through three phases: the incubation period (time of implantation and development of the bacterium, fungus or germ), prodromal period (when the first symptoms begin to appear) and clinical period (when symptoms and Signs of the disease and are diagnosed by various studies).

Non-infectious diseases

Non-infectious diseases are those that are not produced by microbial pathogens. Among them are four main types: deficiencies, degenerative, congenital and mental. Deficiency diseases are those caused by the lack or lack of substances necessary for the proper functioning of the organism, such as rickets that is caused by lack of vitamin D, calcium and phosphorus in the blood.

To mention and define some, degenerative diseases are caused by the progressive deterioration of a particular organ or of the whole organism as the -malon of Parkinson-, the congenital diseases are those that occur from the birth of the person like hemophilia and mental illnesses are those that alter the functioning of the brain and consequently affect the mood and intellectual abilities of people such as schizophrenia.

The causes for the appearance of these diseases are diverse and are usually associated with the environment in which they live, the social environment or the genetics of both parents.

Having indicated the definitions of the terms that concern us, the following table shows the most important differences between infection and non-infectious diseases:

Infectious diseases Non-infectious diseases
They are produced by microorganisms such as fungi, viruses, bacteria, germs, parasites. They are not produced by microbes but by internal and external causes such as the environment, parents, environment, among others.
They are very contagious. They are not contagious.
They are treated by means of pathogen controlling agents. They are treated with different medications or with psychological treatments.
