Respiratory and systematic humoral and cellular immune response of pigs to a heterosubtypic influenza A virus infection [PDF]

, 2001
The level of heterosubtypic immunity (Het-I) and the immune mechanisms stimulated by a heterosubtypic influenza virus infection were investigated in pigs. Pigs are natural hosts for influenza virus and, like humans, they host both subtypes H1N1 and H3N2.

A joint analysis of influenza-associated hospitalizations and mortality in Hong Kong, 1998-2013. [PDF]

, 2017
Influenza viruses may cause severe human infections leading to hospitalization or death. Linear regression models were fitted to population-based data on hospitalizations and deaths.

Changing Epidemiological Pattern and Higher Disease Burden of Influenza in China, 2022 to 2025

Influenza and Other Respiratory Viruses, Volume 19, Issue 9, September 2025.
ABSTRACT Influenza activity peaks in southern (59.62%) and northern China (57.60%) during the 2022/2023 season reached the highest levels in the past 10 years. The 2023/2024 season witnessed a longer duration of the winter–spring epidemic weeks and a higher disease burden compared with previous high‐epidemic years.

Development of the cell-ELISA test for the subtype identification of circulating influenza A(H1) and A(H3) viruses

Microbiology Independent Research Journal, 2015
The sensitive version of cell-ELISA was developed for the subtype-specific differentiation of current influenza A(H1N1)pdm09 and A(H3N2) viruses that are circulating in the human population. This method is based on the estimation of virus reproduction in

Predicting antigenic variants of H1N1 influenza virus based on epidemics and pandemics using a stacking model

PLoS ONE, 2018
H1N1 is the earliest emerging subtype of influenza A viruses with available genomic sequences, has caused several pandemics and seasonal epidemics, resulting in millions of deaths and enormous economic losses.

Antiviral effects and mechanism of Qi pi pill against influenza viruses

Animal Models and Experimental Medicine, Volume 8, Issue 8, Page 1364-1375, August 2025.
Qi pi pill presents anti‐influenza effect and inhibits viral replication in vitro by targeting both the viral RNA replication and the release of new viral particles. Furthermore, QPP modulates the production of proinflammatory cytokines induced by influenza infection in host cells.

Influenza Virus A (H1N1) in Giant Anteaters (Myrmecophaga tridactyla)

Emerging Infectious Diseases, 2009
In February 2007, an outbreak of respiratory disease occurred in a group of giant anteaters (Myrmecophaga tridactyla) at the Nashville Zoo. Isolates from 2 affected animals were identified in March 2007 as a type A influenza virus related to human ...

Proinflammatory cytokine responses induced by influenza A (H5N1) viruses in primary human alveolar and bronchial epithelial cells

Respiratory Research, 2005
Background Fatal human respiratory disease associated with influenza A subtype H5N1 has been documented in Hong Kong, and more recently in Vietnam, Thailand and Cambodia. We previously demonstrated that patients with H5N1 disease had unusually high serum
