What is the difference
To understand the difference between acute respiratory infections and colds, you must first consider each ailment separately.
Features of SARS
ARVI is a disease, the development of which can be affected by the virus. Today it can be parainfluenza, adenovirus or rhinovirus. In addition, even the flu is included in this category. For ARVI, its flow characteristics are inherent.
To suck the SARS of one hypothermia or the use of cold ice cream is not enough. This requires that the pathogenic organism penetrate the human body by airborne droplets. Infection through food, dishes or toys is extremely rare.
The duration of the incubation period of acute respiratory viral infection is only 1.5 days. During this time, pathogenic microorganisms are located in the body and cause damage to the mucosa of the upper respiratory tract.
This leads to the development of a specific clinical picture:
- At the first stage of ARVI development, when the body was not able to give an adequate response to the occurred .At the same time, the patient observes sluggishness, poor appetite. In small patients at this stage, there is a slight nasal congestion, while no discharge is noted.
- In the second stage of the development of acute respiratory viral infections, symptoms such as perspiration, fever, nasal discharge, cough are observed. Severity of symptoms is associated with the virulence of the infection. The flu is characterized by a rise in temperature to 40 degrees from the first days.
A feature of ARVI is that an infection of bacterial etiology can follow it. The reason is that viruses make immunity vulnerable to harmful microbes, on the mucosa of the airways will activate bacteria. For this reason, a person who has already begun to recover, after 3-5 days again feels worse. Although with adequate treatment this happens very rarely.
ARVI can cause the development of various pathologies of the respiratory tract. Here everything depends on what type of pathogen penetrated the body.

How to distinguish the child
About the distinctive features of acute respiratory infections and cold tells the famous pediatrician Komarovsky. He insists that this information should be owned by every parent. The principal feature of these two phenomena is that viruses can not spread without the participation of other cells. Viruses penetrate inside the cell and create their own copies. Thus, each infected cell produces thousands of similar ones. And she perishes or is no longer able to perform her functions. This leads to the development of a certain symptomatology. Another feature of viruses is that they are selective when selecting cells for reproduction. Only those who can subjugate themselves are affected.
