Aim. Assessment of the features of cellular immunological mechanisms at the early stage of HFRS of varying severity and development of prognostic criteria for the risk of a severe course of the infectious process. Materials and methods. An immunological blood test (flow cytofluorimetry method) was performed in 12 patients with severe HFRS and 53 patients with moderate course in the dynamics of the disease. Statistical data processing was performed based on the SPSS software package. Results. At the initial stages of HFRS, immunological features of the severe course of the disease were established in the form of a higher content of T-helper and regulatory T-cells in the blood and a reduced number of CTL, including their activated pool. Based on these changes, an immunological prognostic coefficient of HFRS was developed, which allows determining the risk of severe course in the early days (febrile period) of the disease with high prognostic accuracy. Conclusion. The results obtained allowed us to identify previously unknown features of the immune process at the initial stages of HFRS development, which allowed us to propose a new approach to predicting the severe course of the disease.
