Almost a year of avian influenza in cows. No clues on how this started, no signs of abating, concerns about adatation and some speculation about why here and not in europe science.org/content/articl…

Study finds influenza A antibodies not uncommon in US cattle None of the samples were positive for H5N1 antibodies, but some showed earlier infection from human seasonal flu strains and swine flu strains. cidrap.umn.edu/avian-influenz…

🌍 In response to H5Nx #avianinfluenza spread, Food and Agriculture Organization & World Organisation for Animal Health under GF-TADs, have developed a 10-year strategy (2024–2033) to prevent & control HPAI. The strategy highlights a systems approach for protecting poultry, wildlife & humans. Learn more: woah.org/en/document/gl…

Interested in an easy read to get information about H5N1? Dr. Angela Rasmussen Enikő Hermann and I wrote a short little review. "Highly pathogenic avian influenza H5N1: history, current situation, and outlook" journals.asm.org/doi/10.1128/jv…

WHO, Food and Agriculture Organization & World Organisation for Animal Health updated their assessment of the risk #BirdFlu poses to human health. Based on the information we have, the risk for the general public is low. The risk is low-to-moderate for people who work with potentially infected animals. The risk is continuously monitored

A new African swine fever (ASF) vaccine standard has just been adopted at the #WOAHGS. High quality, effective vaccines paired with existing disease control measures could substantially lower the negative impact of the disease and achieve #ASF control.
