Weekly Virological Update on 19 August 2010
Trend of proportions of different type and subtype influenza viruses:
Summary on week 31
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, Mauritius, Singapore and South Africa. Globally 33.4% of the sub-typed influenza A viruses were pandemic influenza A(H1N1) with circulation as predominant strain locally in New Zealand and India. Sporadic influenza B and/or A(H3N2) activity has been observed in some countries.
For the week 1 August to 7 August 2010. National Influenza Centres (NICs) from 23 countries reported data to FluNet. Of the total 718 specimens reportedly positive for influenza viruses, 585 (81.5%) were typed as influenza A and 133 (18.5%) 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.
