Aim: to study the structure, features of the findings and treatment of mixed infections in children at the present stage.Materials and methods. 85 case histories of children aged 5 months to 17 years and 10 months were examined, the final diagnosis of which included 2 or more infections on the basis of the children's infectious diseases department City Clinical Hospital № 7 of Izhevsk. Children with acute infectious pathology (acute intestinal infections, acute respiratory infections, herpes infections) are hospitalized in this hospital.

Mixed infections are equally common in both boys and girls, while there is a predominance of mixed infections in young children (up to 1 year and from 1 year to 3 years) 62.4%. The structure of infectious morbidity is consistently dominated by acute enteric infection – 83.5% cases and acute respiratory infections – 53.0% cases. The progression of SARS-CoV-2-associated and herpes-associated mixed infections is characterized by a pronounced polymorphism of clinical manifestations. The etiological factor for each nosology was deciphered only in 17.7%; in 43.5% of cases, only one etiological factor was verified in the laboratory; in 38.8% of cases, no etiological factor was confirmed in the laboratory.

Aim: To compare the features of clinical-anamnestic and laboratory-instrumental data and treatment of children with typical and atypical (Mycoplasma) forms of pneumonia.Materials and methods. A comparative analysis was carried out of 1 70 case histories of children in hospital with a verified diagnosis of pneumonia in 2020. The basis for the diagnosis of Mycoplasma pneumonia was a positive PCR result of a smear of the posterior pharyngeal wall. The resulting data was constructed using Microsoft Excel 2007.Results. Mycoplasma pneumonia is specific for older schoolchildren; characterized by: prolonged course (73.5%), long-term preservation of an unproductive cough (75.7%), mild intoxication (68.6%) and catarrhal syndromes (54.3%), gradual onset (76.6%), severe lymphocytosis up to 55%, segmental or polysegmental damage to the lung tissue (92.7%).
