Determinants of Influenza Mortality Trends: Age-Period-Cohort Analysis of Influenza Mortality in the United States, 1959-2016. [PDF]

, 2019
This study examines the roles of age, period, and cohort in influenza mortality trends over the years 1959-2016 in the United States. First, we use Lexis surfaces based on Serfling models to highlight influenza mortality patterns as well as to identify ...

Simultaneous Detection of Influenza A, Influenza B, and Respiratory Syncytial Viruses and Subtyping of Influenza A H3N2 Virus and H1N1 (2009) Virus by Multiplex Real-Time PCR [PDF]

Journal of Clinical Microbiology, 2011
ABSTRACT A multiplex real-time PCR assay was developed to simultaneously detect and discriminate influenza A virus subtypes, including novel H1N1 (2009) and seasonal H3N2 virus, influenza B virus, and respiratory syncytial virus (RSV) in a single test tube, with detection sensitivity and specificity of 99% and 100%, respectively, for the four

Antibodies of influenza A(H1N1)pdm09 virus in pigs’ sera cross-react with other influenza A virus subtypes. A retrospective epidemiological interpretation of Norway's serosurveillance data from 2009–2017 [PDF]

Epidemiology and Infection, 2020
Abstract Since the incursion of influenza A(H1N1)pdm09 virus in 2009, serosurveillance every year of the Norwegian pig population revealed the herd prevalence for influenza A(H1N1)pdm09 (HIN1pdm09) has stabilised between 40% and 50%. Between 30 September 2009 and 14 September 2017, the Norwegian Veterinary Institute and Norwegian Food Safety ...

Genetic and biological characterisation of an avian-like H1N2 swine influenza virus generated by reassortment of circulating avian-like H1N1 and H3N2 subtypes in Denmark [PDF]

, 2013
BACKGROUND: The influenza A virus subtypes H1N1, H1N2 and H3N2 are the most prevalent subtypes in swine. In 2003, a reassorted H1N2 swine influenza virus (SIV) subtype appeared and became prevalent in Denmark.

Detection and isolation of Influenza A virus subtype H1N1 from a small backyard swine herd in Colorado [PDF]

Journal of Veterinary Diagnostic Investigation, 2013
Influenza A virus subtype H1N1 A(H1N1)pdm09 was first confirmed in pigs in the United States in October 2009. In November 2010, lungs and intestines from 2 York piglets from a small, privately owned herd were submitted to the Colorado State University Veterinary Diagnostic Laboratory. The submitting veterinarian reported rapid weight loss and signs of

Could Environment Affect the Mutation of H1N1 Influenza Virus?

International Journal of Environmental Research and Public Health, 2020
H1N1 subtype influenza A viruses are the most common type of influenza A virus to infect humans. The two major outbreaks of the virus in 1918 and 2009 had a great impact both on human health and social development.
