Aloe Polysaccharides Inhibit Influenza A Virus Infection—A Promising Natural Anti-flu Drug

Frontiers in Microbiology, 2018
Influenza A virus causes periodic outbreaks and seriously threatens human health. The drug-resistant mutants have shown an epidemic trend because of the abuse of chemical drugs.

Antiviral Resistance in Influenza: Clinical and Public Health Implications

Influenza and Other Respiratory Viruses, Volume 20, Issue 6, June 2026.
ABSTRACT Timely antiviral treatment and prevention can diminish the morbidity and mortality caused by influenza seasonal, zoonotic, and pandemic infections. However, the emergence of antiviral resistance threatens the utility of available agents and sometimes contributes to poor clinical outcomes.

Pandemic (H1N1) 2009 Transmission during Presymptomatic Phase, Japan

Emerging Infectious Diseases, 2011
During an epidemiologic investigation of pandemic influenza (H1N1) 2009 virus infection in May 2009 in Osaka, Japan, we found 3 clusters in which virus transmission occurred during the presymptomatic phase.

Pathobiology of avian influenza in wild bird species [PDF]

, 2012
Avian influenza viruses, especially highly pathogenic avian influenza viruses (HPAIV), affect a wide range of species, including humans and have thus become a major concern for veterinary medicine and public health.

Surveillance of Migratory Shorebirds and Seabirds in 2024 in Australia Reveals Incursions of a Diversity of Low Pathogenicity Avian Influenza Viruses, but Not High Pathogenicity Avian Influenza H5N1

Influenza and Other Respiratory Viruses, Volume 20, Issue 6, June 2026.
ABSTRACT Background The current panzootic of high pathogenicity avian influenza (HPAI) H5N1 has been catastrophic for wildlife, and following substantial geographic spread, clade 2.3.4.4b is found in every region aside from Oceania. Herein, we report the results of our third year of targeted surveillance of incoming migratory seabirds and shorebirds ...

A Retrospective Cross‐Sectional Study (2009–2023): Exploring Influenza A(H1N1)pdm09 Antibody Time Series in Humans and Swine and Vaccine Coverage in Two Target Groups

Zoonoses and Public Health, Volume 73, Issue 4, Page 336-347, June 2026.
ABSTRACT Introduction Swine may act as ‘epidemiological bridges’ and reservoirs for the emergence of novel zoonotic influenza viruses with pandemic potential. While bidirectional exchange of influenza A viruses at the swine–human interface is well recognised, data on the extent of interspecies transmission are limited.

Verification of the Combimatrix influenza detection assay for the detection of influenza A subtype during the 2007–2008 influenza season in Toronto, Canada

Virology Journal, 2009
The increase in adamantine resistance in influenza A (H3N2) and the emergence of oseltamivir resistance in influenza A (H1N1) has necessitated the use of rapid methodologies to detect influenza subtype.

Comparison of Molecular Assays for the Rapid Detection and Simultaneous Subtype Differentiation of the Pandemic Influenza A (H1N1) 2009 Virus

Journal of Microbiology and Biotechnology, 2012
In April 2009, the H1N1 pandemic influenza virus emerged as a novel influenza virus. The aim of this study was to compare the performances of several molecular assays, including conventional reverse transcription polymerase chain reaction (RT-PCR), two real-time reverse transcription (rRT)-PCRs, and two multiplex RTPCRs.

Immunopotentiation by Natural Extracts: Mechanisms and Applications in Influenza Vaccine Adjuvant Development

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
Natural Extracts as Candidate Influenza Vaccine Adjuvants. Seasonal influenza vaccines face limitations due to viral mutations and low efficacy in vulnerable populations. Traditional adjuvants often have safety or immune‐activation constraints, leading to increased interest in natural extracts from plants, marine organisms, and fungi.

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

, 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.
