Abstract
AIM:
Determine the level of antibodies against socially significant types/serotypes of influenza virus in sera of individuals residing in various regions of Russia.
MATERIALS AND METHODS:
1525 samples of blood sera collected in August-December 2013 in 8 regions of Russian Federation were studied in hemagglutination inhibition reaction (HAI) with antigens obtained from A/California/07/09, (H1N1)pdm09, A/Victoria/361/2011(H3N2), B/Brisbane/60/2008 (Victoria line), B/Massachusetts/2/2012 (Yamagata line), A/Commongull/Chany/2006 (H5N1), A/Anhui/01/2013 (H7N9) influenza virus strains.
RESULTS:
None of the blood sera samples had significant HAI titers against A/H5 and A/H7 antigens. Of all the 1525 samples, 788 (52%) were positive with A(H1N1)pdm09 antigen; 734 (48%) reacted with A(H3N2) antigen; 1010 (66%) samples were positive with B/Victoria antigen and 602 (39%) samples were positive with B/Yamagata antigen.
CONCLUSION:
Healthcare institutions should pay attention to the correction of population immunity profile in regions for the reduction of social-economic losses from seasonal influenza epidemics.
