for more than 3,000 people in the Rio Grande Valley, the virus has been deadly. has teamed with Mayo Clinic Laboratories to commercialize on a global scale. lingering can definitely be exacerbated or worsened by a case of influenza." care in these situations before the loss of blood circulation in the brain causes

The global decline in influenza virus circulation appears to be real and concurrent with the COVID-19 pandemic and its associated community mitigation measures. Influenza virus circulation continues to be monitored to determine if the low activity levels persist after community mitigation measures are eased.

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. 4 The global movement patterns of all four seasonal influenza viruses are illustrated in research published today in the journal Nature, providing a detailed account of country-to-country virus Influenza activity started in week 45/2019 and returned to baseline levels in week 13/2020, earlier than previous seasons. Influenza viruses circulated at high levels between weeks 52/2019 and 10/2020 (based on increased proportions (40% and above) of sentinel specimens testing positive for influenza viruses). 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 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 Understanding the spatiotemporal patterns of emergence and circulation of new human seasonal influenza virus variants is a key scientific and public health challenge. 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.

similar influenza viruses can cause global epidemics at almost the same time.16 winter peak in temperate regions and year-round circulation with minor peaks

2020 - 2021. Influenza Laboratory Surveillance Information by the Global Influenza Surveillance and Response System (GISRS) 8 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.

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.

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. 4 Understanding the spatiotemporal patterns of emergence and circulation of new human seasonal influenza virus variants is a key scientific and public health challenge. 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 we show that the global circulation patterns of A/H1N1 (up to Click on the article title to read more. 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.

GISRS operates through a worldwide network of laboratories that provides real‐time surveillance information on the circulation and evolution of influenza viruses. Understanding global influenza migration and persistence is crucial for vaccine strain selection. Using 240 new human influenza A virus whole genomes collected in Vietnam during 2001–2008, we looked for persistence patterns and migratory connections between Vietnam and other countries.
