Dengue fever is classified as one of the most common viral diseases with a transmission mechanism implemented through arthropod vectors. The expansion of of the Aedes aegypti mosquito is leading to a significant increase in the number of cases of dengue fever in more than 100 countries, highlighting the importance of developing and implementing specific prevention and treatment measures. Etiotropic drugs with proven efficacy against the pathogen are not registered, and the use of the vaccine is approved only among seropositive individuals.

The article presents an analysis of the developed experimental version of ELISA test-systems for the detection of specific antibodies to the virus influenza A(H1N1)pdm09, and their dynamics at different stages of infection as compared with those of the traditional HAI method. The study included 20 paired samples of serum from patients hospitalized at different stages of the disease with etiology associated with the influenza virus A(H1N1)pdm09.

Material And Methods: International cohort open non-interventional .study <
In the 2015-2016 epidemic season, there were dominant influenza A(H1N1)pdm09 strains (over 90%) among the circulating influenza viruses in most countries of the Northern Hemisphere and in Russia. A study of the antigenic properties of influenza A(H1N1)pdm09 strains revealed no differences in those of vaccine virus. Sequencing showed that there were amino acid substitutions in hemagglutinin (receptor binding and Sa sites) and in the genes encoding internal proteins (PA, NP, M1, and NS1).
