"Bird Flu's Impact on Dairy Cattle and Human Risk: What You Need to Know"

Scientists are concerned about the potential risks to humans as bird flu spreads among dairy cattle, with a focus on understanding virus mutations that could make it a threat to mammals. While the virus has shown some signs of evolving to better replicate inside mammals, it has not yet demonstrated efficient airborne transmission between humans. Research on virus transmission in mammals, particularly through experiments on ferrets, offers some clues but also highlights the need for caution in interpreting the results.
