CDC Delays Reveal Bird Flu Spread in Cows and People
A CDC study, delayed amidst a communication freeze, reveals evidence of undetected H5N1 bird flu transmission from cattle to humans, with three veterinarians testing positive for antibodies despite lacking symptoms. The findings highlight inadequate surveillance, particularly given a veterinarian’s positive result in a state without reported cattle infections. This underscores the difficulty in tracking human infections, emphasizing the need for improved surveillance of cattle and dairy workers to prevent future outbreaks. The low number of detected cases may reflect limitations in current testing methods, suggesting a higher prevalence of undiagnosed infections.
