Through a systematic analysis of published and unpublished studies, and publicly available surveillance data, the authors model the global circulation of these viruses in 246 locales and explore the climatic drivers of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.

ECDC will produce its seasonal influenza risk assessment once active circulation of influenza viruses starts in Europe. Download Rapid risk assessment: circulation of drifted influenza A(H3N2) viruses in the EU/EEA, 22 December 2014 - EN - [PDF-98.09 KB] Circulation of Influenza Virus & Selection of Vaccine Strains. Initially WHO global vaccine recommendations from 2000–2001 to 2012–2013 for the northern Jun 8, 2015 The global circulation patterns of influenza A/H3N2 viruses are well characterized1,2,3,4,5,6,7, but the patterns of A/H1N1 and B viruses have Mar 1, 2021 Knowledge gaps remain regarding the role of influenza viruses in of influenza A(H1N1)pdm09 virus circulation) in a manner that could not be test of persistence versus seeding is to examine the origin of strains isolated between epidemics.

Global circulation of influenza viruses

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 2015-06-08 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 … 2019-12-03 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 Southeast Asia (E-SE Asia) via a region-wide network of temporally overlapping epidemics The global circulation patterns of influenza A/H3N2 viruses are well-characterized but the patterns of A/H1N1 and B viruses have remained largely unexplored. 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. 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.

25 sep. 2020 — The world health report 1999: Making a difference.

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

mortality worldwide. 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.

The global circulation patterns of influenza A/H3N2 viruses are well-characterized but the patterns of A/H1N1 and B viruses have remained largely unexplored. 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

However, influenza notifications were 7,029 (March–September) compared with an average 149,832 for the same period in 2015–2109, despite 2008-04-01 Global circulation patterns of seasonal influenza viruses vary with antigenic drift Trevor Bedford 1 , Steven Riley 2,3 , Ian G. Barr 4 , Shobha Broor 5 , Mandeep Chadha 6 , Nancy J. Cox 7 2008-09-12 Background: Global influenza virus circulation decreased during the COVID-19 pandemic, possibly due to widespread community mitigation measures. Cambodia eased some COVID-19 mitigation measures in June and July 2020. On 20 August a cluster of respiratory illnesses occurred among residents of a pagoda, including people who tested positive for influenza A but none who were positive for SARS-CoV … 2016-05-01 We have previously described the circulation and seasonality of influenza viruses in Cambodia during six consecutive years (2006‐2011) following the establishment of the Cambodian National Influenza Centre (NIC) in 2006. 8-10 These previous data demonstrated a peak in influenza circulation during the rainy season from June to November, which is consistent with influenza circulation in the The global anxiety and a significant threat to public health due to the current COVID-19 pandemic reiterate the need for active surveillance for the zoonotic virus diseases of pandemic potential.
