Scientists finally solved how H5N1 bird flu hid in dairy cows

Scientists have figured out why H5N1 bird flu targets dairy cows' udders, revealing that the virus's receptors are abundant in mammary tissue. This discovery not only explains the unusual infection pattern but also offers a potential predictive tool for spotting future outbreaks and preventing widespread spread. Understanding this mechanism could be crucial in developing better strategies to combat bird flu and its potential spillover effects to other species.
