US Dairy Cows Infected with H5N1 Bird Flu, Sparking Mutation Concerns
Millions of Wild Birds Perish in Avian Influenza Outbreak
The highly contagious avian influenza H5N1, which has caused widespread deaths in wild bird populations globally, has now been detected in US dairy cattle. This unprecedented development has raised alarm among health officials, who are closely monitoring the situation for potential mutations that could pose a threat to humans.
Sporadic Infections in Mammals
While H5N1 infections in mammals are rare, there have been sporadic cases reported in recent years. However, the emergence of the virus in US dairy cattle has heightened concerns, as it may indicate a broader adaptation of the virus to mammals.
According to the US Department of Agriculture, two dairy cows in Wisconsin have tested positive for H5N1. The cows were part of a large herd, and all infected animals have been euthanized to prevent further spread.
The CDC has emphasized that the risk of H5N1 transmission to humans from consuming poultry or eggs is low. However, individuals who work with infected poultry or come into close contact with sick birds should take precautions to avoid infection.
