Children with acute infectious pathology (acute intestinal infections, acute respiratory infections, herpes infections) are hospitalized in this hospital. Diagnostic methods: polymerase chain reaction, ELISA, bacteriological.Results. 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.
