Influenza Virus Antigen Detection by Immunofluorescence Assay (IFA)
Clinical specimens from 1107 patients with ILI and ARI were investigated by IFA in 36 RBLs for detection of antigens of influenza viruses, parainfluenza, RSV and adenoviruses. A total of 51 (4.7%) influenza cases were diagnosed including:
- 2 (0.2%) influenza (H1N1+H1N1v) cases in 1 city,
- 13 (1.2%) influenza A(H3N2) cases in 4 cities,
- 36 (3.3%) influenza B cases in 13 cities.
Mid-value for IFA detection of influenza and other non-influenza respiratory viruses in the country was estimated as 25.0%, including non-influenza respiratory viruses as 20.3% accounting as 12.4%, 6.1% and 1.8% for parainfluenza, adeno- and RS-viruses, correspondingly (table 2).
...
Conclusion
During the week ending January 02.2011 the overall proportion of respiratory samples tested by virus isolation, IFA and rRT-PCR positive for influenza was estimated as 9.9%. A total of 8 influenza viruses were isolated including 2 pandemic A(H1N1)v viruses, 1 influenza A(H3N2) viruses, and 5 influenza B viruses. Epidemic thresholds of morbidity for separate cities were exceeded in 17 RBLs of 49 collaborating with WHO NIC in St.-Petersburg. Morbidity level in these cities was ranged from 0.4% to 1.7% of overall population.This week nationwide ILI and ARI registered morbidity level (53.7 per 10 000) was lower than the national baseline by 13.8% that can be explained by New Year holidays in Russia.
