Although it does not generally infect humans, a single mutation of the H5N1 virus in the highly pathogenic avian and bovine clade 2.3.4.4b could overcome this barrier and possibly trigger a pandemic. Scientists at The Scripps Research Institute have warned of this possibility after studying the three-dimensional structure of the viral hemagglutinin and seeing how a change in one amino acid would make it more suitable for the human cell receptor. The researchers stress the need to monitor new mutations of this virus in order to act quickly in case the global jump to our species occurs.
