[The use of immunoenzyme analysis in studying the etiologic structure of influenza morbidity in 1985-1988].
In the periods of epidemic increases in the incidence of influenza in 1985-1988, approximately 600 patients with clinical diagnoses of ARVI and influenza were examined for the presence of viral antigen in nasopharyngeal washings by solid-phase enzyme-immunoassay and for antibody rises in paired blood sera. The use of modified SPEIA and original test sera for influenza type A and B viruses in rapid diagnosis of influenza made it possible to decode the etiology of the epidemic situations in 1985-1988. Influenza A and B virus antigens were detected in a high portion of the examined nasopharyngeal washings. The analysis of the distribution of positive results in the detection of viral antigen in the clinical specimens and in influenza serodiagnosis demonstrated a high correlation of the results (93.9%). The etiological pattern of influenza in recent years is characterized by simultaneous circulation in the human population of influenza A (H1N1, H3N2) and B viruses, as reflected by detection of mixed infections in 1-3% of the cases.
