Global circulation of influenza viruses

Li and colleagues’ modelling approach relies on estimating the fraction of viruses circulating in each month of the year, in line with previous work.3 They find marked influenza virus seasonality in temperate Antigenic and genetic analysis of the hemagglutinin of approximately 13,000 human influenza A (H3N2) viruses from six continents during 2002-2007 revealed that there was continuous circulation in east and Southeast Asia (E-SE Asia) via a region-wide network of temporally overlapping epidemics and that epidemics in the temperate regions were seeded from this network each year. 2015-07-01 Here we show that the global circulation patterns of A/H1N1 (up to 2009), B/Victoria, and B/Yamagata viruses differ substantially from those of A/H3N2 viruses, on the basis of analyses of 9,604 haemagglutinin sequences of human seasonal influenza viruses from 2000 to 2012. 2020-09-17 Through a systematic analysis of published and unpublished studies, and publicly available surveillance data, the authors model the global circulation of these viruses in 246 locales and explore the climatic drivers of seasonality. Introduction. Antiviral agents are part of the initial response plans for pandemic influenza and play a key role in protecting high‐risk populations from seasonal influenza. 1 , 2 , 3 In recent years, the widespread circulation of seasonal A(H3N2) viruses resistant to the aminoadamantanes and seasonal A(H1N1) viruses resistant to the neuraminidase inhibitor oseltamivir has been observed.

Global circulation of inﬂuenza The spread of inﬂuenza A/H3N2 virus globally has been well characterised. Each year epidemics of A/H3N2 result from new genetic variants, which then spread from East and South-East Asia. A/H3N2 genetic variants do not persist locally between epidemics but are re-seeded from East and Southeast Asia.

Australia expected co-circulation of severe acute respiratory syndrome coronavirus 2, influenza and other seasonal respiratory viruses. However, influenza notifications were 7,029 (March–September) compared with an average 149,832 for the same period in 2015–2109, despite substantial testing.

Influenza is a contagious respiratory illness caused by influenza viruses. 2020 –21 influenza season will coincide with the continued or recurrent circulation of

The title is very catchy and misleading. The WHO's virus circulation graph and the text did NOT describe it as "Completely Disappeared in 2020." It did reporting having seen very minuscule amount of flu virus detected, instead. https://www.who.int/influenza/gisrs_laboratory/updates/flune Edit: now the title has been updated, it's more accurate
