2019-12-20 · Of the sub-typed influenza A viruses, 1216 (30.2%) were influenza A (H1N1)pdm09 and 2809 (69.8%) were influenza A (H3N2). Of the characterized B viruses, 25 (5.2%) belonged to the B-Yamagata lineage and 458 (94.8%) to the B-Victoria lineage. View the full influenza update Global circulation of influenza viruses

Circulation patterns of influenza A/H3N2 have been well characterized (see for example Russell et al. 2008, Bedford et al. 2010 and Lemey et al. 2014), showing little regional persistence and a powerful source-sink dynamic in which viruses emerge from the East and Southeast Asian tropics and spread to the rest of the world, rapidly replacing endemic lineages.

On average, influenza viruses infect 5 to 15% of the global population, resulting in ~500,000 deaths annually (1). De-spite substantial progress in many areas of influ-enza research, questions such as when and to what extent the virus will change antigenically, and to what extent viruses spread globally, re-main unanswered. There are 3 main types of circulating influenza viruses in the world: A, B, and C. Influenza viruses (of the family Orthomyxoviridae) are enveloped negative-strand RNA viruses with segmented genomes. Of its two genera, one includes influenza A and B viruses, and the other influenza C virus. provide the first comprehensive analysis of the global seasonality of these four most common viruses. Through a systematic analysis of published and unpublished studies, and publicly available surveillance data, the authors model the global circulation of these viruses in 246 locales and explore the climatic drivers of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. movements of influenza A virus will require greatly expanded global surveillance, particularly of tropical regions where the virus circulates year-round, and during non-epidemic periods in temperate climate areas.

Here, based on analyses of 9,604 hemagglutinin sequences of human seasonal influenza viruses from 2000-2012, we show that the global circulation patterns of A/H1N1 (up to 2009), B/Victoria, and B/Yamagata viruses differ substantially from Antigenic and genetic analysis of the hemagglutinin of ∼13,000 human influenza A (H3N2) viruses from six continents during 2002–2007 revealed that there was continuous circulation in east and Global influenza virus circulation declined and has been below tradi - tional seasonal levels during the COVID-19 pandemic.1- 3 After learn-ing of increased influenza virus circulation in some tropical Asian countries, we reviewed current surveillance data to better ascertain data, the authors model the global circulation of these viruses in 246 locales and explore the climatic drivers of seasonality. 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.
