Influenza and ARI morbidity data. Influenza activity increased significantly on the week 04.2016. The nationwide ILI & ARI morbidity level (91.9 per 10 000 of population) exceeded the national baseline by 32.2%. Etiology of ILI & ARI morbidity. The overall proportion of respiratory samples positive for influenza in traditional surveillance system was estimated as 33.6%. Influenza A(H1N1)pdm09 dominated (91.9% of influenza cases). Influenza A(H3N2) and B cases registered sporadically. Percent of positive ARI cases of non-influenza etiology (PIV, adeno- and RSV) was estimated as 19.6% of investigated patients by IFA and 7.3%by PCR.
In sentinel surveillance systemclinical samples from 68 SARI and 60 ILI/ARI patients were investigated by rRT-PCR. 21 (30.8%) influenza A(H1N1)pdm09 cases among SARI patients and 10 (16.7%) influenza A(H1N1)pdm09 cases among ILI/ARI patients were detected.

Two A(H3N2) strains were similar to influenza A/Hong-Kong/4801/2014 virus, with antiserum to influenza A/Switzerland/9715293/2013 they reacted up to 1/4 - 1/8 of homological titer. Genetic characterization. 11 investigated influenza A(H1N1)pdm09 virus strains were A/South Africa/3626/2013-like. All viruses bear clade 6B specific mutations in HA (S84N, S162+N and I216T) and formed new genetic group according to phylogenetic analysis. One A(H1N1)pdm09 sequence obtained directly from autopsy sample showed the presence of additional mutation D222G in HA1.

Epidemiological data showed increase of influenza activity in Russia in comparison with previous week. Tthe nationwide ILI & ARI morbidity level (60.8 per 10 000 of population) was below the national baseline (69.5 per 10 000) by 12.5%.
ILI and ARI epidemic threshold was exceeded in 1 of 59 cities collaborating with two WHO NICs in Russia. Influenza.

Cumulative number of diagnosed influenza cases
Laboratory diagnosis data. Results of influenza laboratory diagnosis by different tests were submitted by 53 RBLs and two WHO NICs. According to these data as a result of 3052 patients investigation the overall proportion of respiratory samples positive for influenza virus was estimated as 563 (18.4%) including 462 (82.1%) influenza A(H1N1)pdm09 cases, 25 (4.4%) influenza A(H3N2) cases, 14 (2.5%) influenza A cases and 62 (11.0%) influenza B cases.
... [h=3]Conclusion[/h] Influenza and ARI morbidity data. Influenza activity increased on the week 12.2016. The nationwide ILI & ARI morbidity level (60.8 per 10 000 of population) was below the national baseline by 12.5%. Etiology of ILI & ARI morbidity. As a result of investigation of 3052 patients in 53 cities of Russia the overall proportion of respiratory samples positive for influenza in traditional surveillance system was estimated as 18.4%. Influenza A(H1N1)pdm09 dominated (82.1% of influenza cases). Influenza A(H3N2) and B cases registered sporadically.
The overall proportion of respiratory samples tested positive for parainfluenza, adenovirus and RSV was estimated in total as 9.3% (PCR) and 19.3% (IFA) of investigated samples.
In sentinel surveillance systemclinical samples from 44 SARI and 71 ILI/ARI patients were investigated by rRT-PCR. 8 (18.2%) influenza cases were detected including 5 influenza A(H1N1)pdm09, 1 influenza A(H3N2) and 2 influenza B cases. A total 10 (14.1%) influenza cases including 7 influenza A(H1N1)pdm09 and 3 influenza A(H3N2) cases were detected among ILI/ARI patients. Antigenic characterization. Totally 309 influenza viruses including 292 influenza A(H1N1)pdm09 viruses, 10 influenza A(H3N2) strains and 7 influenza B viruses were characterizated antigenically in two NICs of Russia since the beginning of the season. Influenza A(H1N1)pdm09 strains were related closely to influenza A/California/07/09 virus. 10 A(H3N2) strains were similar to influenza A/Hong-Kong/5738/2014 virus, with antiserum to influenza A/Switzerland/9715293/2013 they reacted up to 1/4 - 1/8 of homological titer in HI. All investigated 7 influenza B viruses belonged to Victorian lineage and antigenically were similar to influenza B/Brisbane/60/2008 reference strain reacting with antiserum to it up to 1 - 1/8 of homological titer in HI. Genetic characterization.
64 investigated influenza A(H1N1)pdm09 virus strains were A/South Africa/3626/2013-like. All viruses bear clade 6B specific mutations in HA (S84N, S162+N and I216T) and formed new genetic group according to phylogenetic analysis. Two A(H1N1)pdm09 sequence obtained directly from autopsy sample showed the presence of additional mutation D222G in HA1. Data on 54 influenza strains presented in GISAID base data. Two influenza B viruses belong to clade 1A B/Brisbane/60/2008. Susceptibility to antiviral drugs. According to genetic investigations of NA and M gene of 54 influenza A(H1N1)pdm09 all viruses were susceptible to oseltamivir and resistant to rimantadine. 72 influenza A(H1N1)pdm09 strains and 5 influenza B viruses were susceptibility to oseltamivir according to Munana test.
