Active Surveillance for Avian Influenza Virus, Egypt, 2010–2012

Emerging Infectious Diseases, 2014
Continuous circulation of influenza A(H5N1) virus among poultry in Egypt has created an epicenter in which the viruses evolve into newer subclades and continue to cause disease in humans.

Interaction between avian influenza subtype H9N2 and Newcastle disease virus vaccine strain (LaSota) in chickens [PDF]

BMC Veterinary Research, 2018
Background H9N2 avian influenza virus is endemic in Egyptian poultry flocks. The role of the live viral vaccines such as LaSota in exaggeration of the clinical picture of H9N2 infection under field conditions is significantly important leading to severe economic losses due to higher mortality and lower growth performance.

Toward Predicting Pandemic Potential: A Comparative Analysis of Virus‐Host Interactions Between Diverse Influenza A Viruses and the Human Innate Immune System

PROTEOMICS, EarlyView.
ABSTRACT Zoonotic infections caused by influenza A viruses (IAVs) of animal origin are a major public health concern, as they may represent the initial step toward the emergence of a pandemic strain. The host range of IAVs is shaped by species‐specific virus‐host interactions, and several host barriers have been identified that restrict the adaptation ...

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.

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents

Advanced Functional Materials, Volume 36, Issue 26, 30 March 2026.
Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...
