Research Reveals H5N1 Bird Flu Targets Cattle Udders Instead of Lungs

Researchers have uncovered why H5N1 bird flu attacks cows udders instead of their lungs: the virus preferentially binds to receptors concentrated in mammary tissue rather than respiratory tissues.

Scientists have conducted research revealing new characteristics of the H5N1 bird flu virus. The study found that the H5N1 virus tends to target udder tissue in cattle rather than lung tissue. The virus preferred receptors are highly concentrated in mammary tissue. This discovery helps explain the infection mechanism of the virus in dairy cattle. Researchers made this finding through analysis of viral receptor distribution patterns. The research provides important guidance for bird flu prevention and control efforts. Scientists will continue investigating how the virus behaves across different animal species. This study will help improve epidemic prevention and control strategies in the future.
