Influenza in Bird Feces
Global surveillance of avian influenza viruses in 10 countries along major migratory bird flyways has uncovered significant strain diversity, with H5N1 being the most prevalent strain. This study also marks the first AIV reports from several underrepresented regions and identifies key transmission hotspots. The findings underscore the critical need for targeted surveillance in high-risk zones to monitor viral evolution and mitigate spillover risks.
