FIELD: biotechnologies.
SUBSTANCE: method to determine virulent and pathogenic forms of flue viruses is based on collection of an initial sample of a tissue/physiological fluid from patients who are possibly sick with flu, extraction and treatment of RNA preparations from the initial sample, synthesis of cDNA on the RNA matrix, analysis of a nucleotide sequence of the produced cDNA with the purpose to identify the mutation status of specific positions of flu virus segments, and calculation of two scoring-factors, by the value of which they decide on extent of virulence and pathogenicity of a flu virus.
EFFECT: method may be used to determine virulent and pathogenic forms of flu virus.
