Abstract
Upper respiratory tract infections (HCD) are rarely fatal, but they are a source of extreme morbidity, causing two to three diseases in adults every year. In childhood, respiratory tract infections are the leading cause of antibiotic prescription in morbidity and outpatient care.
Initial therapy is for the most part empirical and rarely specific based on culture results. However, even the culture examination may not be interpreted correctly, resp. the place of collection of the material need not be in relation to the organ disability.
The upper part of the respiratory tract is inhabited by a diverse variety of microorganisms in a healthy population. However, the vast majority of respiratory diseases are of viral etiology and antibiotic treatment, on the other hand, has an adverse effect.
The lower respiratory tract, protected by ciliated epithelium, mucus, and macrophages, is simple in a healthy individual. Respiratory infections in outpatient practice are the most common cause of antibiotic prescription and account for up to two-thirds of total antibiotic prescription.
In addition, the vast majority of respiratory infections are caused by viruses that are not affected by antibiotics; on the contrary, their administration can harm the patient.
