ARVI Symptoms

Respiratory infections (ARVI) are shown by a lesion of top area mucosa of respiratory tracts. Disease has various symptomatology as it is caused by some viruses not by a single.

For example, one virus affects vocal chords and changes voice sounding, causing hoarseness or loss of voice, another is characterized with hysterical tussis and inflamed larynx and trachea; temperature increase may not be available. Second (rhinovirus) causes sneezing, itch (irritation) in pharynx, dryness in nose. Through a short time slime starts being emitted plentifully from nose; body temperature rises to 37° C. The next virus (adenovirus) affects palatine tonsils, in this case there is a painful swallowing, “sandpaper” in eyes, whitish films are formed on tonsils and in throat. The lymph-node hyperplasia is possible.

One more virus (respiratory syncytial) “specializes” on bronchi. Its harmful action is caused by difficulty of exhalation, lack of air similar to asthmatic, and ronchi in lungs. This virus is localized in the top area mucosa of respiratory tracts, gets into cells of a protective mucosa, blasting them and tearing away. Sawn-off cells contain an active virus, at tussis or sneezing are transferred by air in droplets of a sputum infecting new people.

The most interesting is that fact that till nowadays didn’t develop a ARVI inoculation as it is absolutely impossible because of a significant amount of kinds of these viruses, and also their fulminant opportunity to change.
