The prevalence of sharp respiratory diseases is very wide. The disease affects all age groups of the population. It is known that every adult man per year is sick of a sharp respiratory disease from 2 to 4 times. This forms a greater danger of complications in the lungs-free and creates a large number of cases of disability, and therefore gives material damage. The effect on the organism of the causative agent of acute respiratory viral infection can vary significantly depending on the etiology, age of the patient, the state of his immune system, and the presence of concomitant diseases. Against the background of the height of the disease, symptoms of intoxication prevail chills, a sharp headache with overwhelming localization in the frontal region and temples, pain in the muscles and joints, pain when the eyeballs move or when pressure is applied to them, lacrimation, severe weakness, and fatigue. With acute respiratory disease, intoxication, hemorrhagic and respiratory syndromes are developing. The relative benignness and short-term flow of this disease leads to the fact that the majority of patients do not seek medical attention. For this reason, it is far from always possible to diagnose the species affiliation of the pathogen.
