Update on Ophthalmic Implications of Highly Pathogenic Avian Influenza A (H5N1) Virus

Pathogens
Introduction: Highly Pathogenic Avian Influenza (HPAI) A(H5N1) represents a growing public health challenge, given broadening zoonotic vectors, with a previously reported human mortality rate of roughly 50%. Late March 2024 marked the start of a new outbreak of HPAI A(H5N1) in the United States.

Inactivated H5 antigens of H5N8 protect chickens from lethal infections by the highly pathogenic H5N8 and H5N6 avian influenza viruses

Journal of Veterinary Research, 2018
Introduction: Highly pathogenic Asian H5-subtype avian influenza viruses have been found in poultry and wild birds worldwide since they were first detected in southern China in 1996. Extensive control efforts have not eradicated them.

A VSV-vector vaccine simultaneously targeting H5N1 hemagglutinin and matrix protein 2 induces robust neutralizing and ADCC antibody responses and provides full protection against lethal H5N1 infection in a mouse model

Journal of Virology
Avian influenza A viruses, especially highly pathogenic avian influenza (HPAI) viruses, pose a significant public health threat, and a multivalent vaccine is the primary prophylactic measure to control these viruses.

Spillover of highly pathogenic avian influenza H5N1 virus to dairy cattle

Nature
The highly pathogenic avian influenza (HPAI) H5N1 virus clade 2.3.4.4b has caused the death of millions of domestic birds and thousands of wild birds in the USA since January 2022 (refs. 1-4). Throughout this outbreak, spillovers to mammals have been frequently documented5-12.
