Highly pathogenic avian influenza virus H5N1 clade 2.3.4.4b in wild rats in Egypt during 2023
Avian influenza viruses (AIVs) pose continuous challenges to human and animal health worldwide. Wild birds are considered the natural reservoir for AIVs and play a major role in spreading influenza viruses over long distances.
Detection and Monitoring of Highly Pathogenic Influenza A Virus 2.3.4.4b Outbreak in Dairy Cattle in the United States
The emergence and spread of highly pathogenic avian influenza virus A subtype H5N1 (HP H5N1-IAV), particularly clade H5N1 2.3.4.4b, pose a severe global health threat, affecting various species, including mammals.
Highly Pathogenic Avian Influenza (HPAI) H5N1 Virus in Livestock
The primary introduction of disease into dairy herds has been predominantly via exposure to wild birds. The exact mechanism of spread is currently unknown, although there is potential for viral spread through milk.
Cluster of Influenza A(H5) Cases Associated with Poultry Exposure at Two Facilities — Colorado
Persons who work in close contact with dairy cattle and poultry that are infected with highly pathogenic avian influenza (HPAI) A(H5N1) virus are at increased risk for infection.
Three new studies probe the efficacy of antivirals in preventing and treating influenza
Two find that the drugs may shorten hospital stays and decrease the risk of infection in those at high risk for severe illness, and one concludes that timely initiation reduces the risk of death from flu-related pneumonia.
Estimated number of lives directly saved by COVID-19 vaccination programmes in the WHO European Region from December, 2020, to March, 2023: a retrospective surveillance study
By March, 2023, 54 countries, areas, and territories (hereafter CAT) in the WHO European Region had reported more than 2·2 million COVID-19-related deaths to the WHO Regional Office for Europe.
Infection of South American coatis (Nasua nasua) with highly pathogenic avian influenza H5N1 virus displaying mammalian adaptive mutations
Deadly outbreaks among poultry, wild birds, and carnivorous mammals by the highly pathogenic H5N1 virus of the clade 2.3.4.4b have been reported in South America.
Opportunities and challenges for the U.S. laboratory response to highly pathogenic avian influenza A(H5N1)
On March 25, 2024 an outbreak of highly pathogenic avian influenza (HPAI) A H5N1 was identified in dairy cows across multiple farms in the United States.
France to launch 2nd vaccination campaign against AI H5N1
In a significant move to protect its poultry industry, France is set to launch its second commercial vaccination campaign against Avian Influenza H5N1.
Antivirals for treatment of severe influenza: a systematic review and network meta-analysis of randomised controlled trials
The optimal antiviral drug for treatment of severe influenza remains unclear. To support updated WHO influenza clinical guidelines, this systematic review and network meta-analysis evaluated antivirals for treatment of patients with severe influenza.
