Influenza A(H1N1)pdm09 virus infection in marine mammals in California

Emerging Microbes & Infections, 2013
Dear Editor, In a recent report, some of the coauthors of this letter documented the isolation of influenza A(H1N1)pdm09 from northern elephant seals (NES, Mirounga angustirostris) in California in 2010.1 The two virus sequences were most similar to a December 2009 human isolate from San Diego, California, raising many questions as to the timing and

Impact of Influenza A(H1N1)pdm09 Virus on Circulation Dynamics of Seasonal Influenza Strains in Kenya [PDF]

The American Society of Tropical Medicine and Hygiene, 2013
We describe virus variations from patients with influenza-like illness before and after the appearance of influenza A(H1N1)pdm09 in Kenya during January 2008–July 2011. A total of 11,592 nasopharyngeal swabs were collected from consenting patients. Seasonal influenza B, A/H1N1, A/H3N2, A/H5N1, and influenza A(H1N1)pdm09 viruses were detected by real ...

Adaptation of influenza A(H1N1)pdm09 virus in experimental mouse models

Infection, Genetics and Evolution, 2016
In the present study, three mouse-adapted variants of influenza A(H1N1)pdm09 virus were obtained by lung-to-lung passages of BALB/c, C57BL/6z and CD1 mice. The significantly increased virulence and pathogenicity of all of the mouse-adapted variants induced 100% mortality in the adapted mice.

A host-based whole genome sequencing study reveals novel risk loci associated with severity of influenza A(H1N1)pdm09 infection

Emerging Microbes and Infections, 2021
Influenza A(H1N1)pdm09 virus has remained in a seasonal circulation since being recognized in 2009. Although it followed a mild course in most patients, in others it caused a series of severe clinical illnesses. Epidemiologic studies have implicated that

Epidemiological and virological characteristics of pandemic influenza A (H1N1) 2009 in school outbreaks in China [PDF]

, 2012
Background: During the 2009 pandemic influenza H1N1 (2009) virus (pH1N1) outbreak, school students were at an increased risk of infection by the pH1N1 virus. However, the estimation of the attack rate showed significant variability. Methods: Two school

The survival of influenza A(H1N1)pdm09 virus on 4 household surfaces

American Journal of Infection Control, 2014
We investigated the survival of a pandemic strain of influenza A H1N1 on a variety of common household surfaces where multiple samples were taken from 4 types of common household fomite at 7 time points. Results showed that influenza A H1N1sw virus particles remained infectious for 48 hours on a wooden surface, for 24 hours on stainless steel and ...

A Sequence-Based Update on Amino Acid Substitutions in Influenza Polymerase Acidic Protein in Europe That Alter Baloxavir Susceptibility From 2009 to 2025. [PDF]

Influenza Other Respir Viruses
ABSTRACT Background Influenza causes 650,000 deaths, 3–5 million hospitalizations, and 1 billion cases worldwide each year. There is a limited repertoire of antivirals available to tackle this burden, highlighting the risk of developing resistance to current drugs.
