Weekly Virological Update on 26 August 2010
Trend of proportions of different type and subtype influenza viruses:
Summary on week 32
Global Virological Surveillance
Overall influenza activity has remained low. Co-circulation of pandemic A(H1N1), A(H3N2) and influenza B viruses was reported from Australia, China, Chile and India.
Globally 71.2%+ of the sub-typed influenza A viruses were pandemic influenza A(H1N1) circulating. This is the predominant virus in New Zealand and India.
Elsewhere sporadic activity of pandemic influenza A(H1N1) , influenza B and/or A(H3N2) was detected in some countries.
For the week 8 August to 14 August 2010. National Influenza Centres (NICs) from 25 countries reported data to FluNet. Of the total 1,043 specimens reportedly positive for influenza viruses, 947 (90.8%) were typed as influenza A and 96 (9.2%) as influenza B.
WHO, through the GISN, continues monitoring the global circulation of influenza viruses, including pandemic, seasonal and other influenza viruses infecting, or with the potential to infect humans.
** Some NICs report data to FluNet retrospectively and updates of previous data with new results are frequent.
