CDC study finds silent H5N1 transmission in veterinarians, raising surveillance concerns.
A recent CDC study found that three out of 150 veterinarians had antibodies to H5N1 bird flu without showing symptoms, indicating silent transmission from animals to humans.
This suggests the virus may be spreading more widely than reported, as infected individuals may not seek medical care.
The study highlights the need for better surveillance and emphasizes precautions for those handling sick or dead birds.
