Bird flu found in horses could threaten human health

In Mongolia, a recent study conducted by scientists at the University of Glasgow revealed the presence of bird flu antibodies in horses, indicating they might be vulnerable to the virus without displaying symptoms. This finding raises concerns about the potential transmission of the H5N1 virus to humans, particularly since horses are often in close contact with people. The researchers warned that if this virus establishes itself within horse populations, the risk of human infection could significantly increase. Furthermore, the study points to the possibility that horses could serve as a mixing vessel for new strains of influenza, especially in the event of simultaneous infections with different variants of the virus. As H5N1 is currently spreading among cattle in the US, with reports indicating that over 700 dairy herds in 15 states have been affected, the implications of this discovery require urgent attention. Authorities have noted that almost 60 farm workers have also contracted the virus, albeit with mild symptoms thus far. The slow response of US health officials has drawn criticism, emphasizing the need for increased monitoring and testing to preemptively address potential outbreaks. Experts warn that allowing H5N1 to circulate longer in various animal populations increases the risk of mutated strains that could become more harmful to humans. With the UK Health Security Agency asserting that the virus poses a low risk to cattle in Britain, precautionary measures are still being implemented, including the order for five million H5 vaccine doses should the need arise. The wider implications of this study underscore the importance of surveillance across animal populations to safeguard public health.
