This crossing of interspecies barriers by the virus creates a real danger of pandemic manifestations in humans . The continued spread of H5N1 clade 2.3.4.4b in dairy populations and other mammalian species and efficient animal-to-animal transmission increases the risk of infection and subsequent spread of the virus in human populations. According to registers, as of 1 November 2022, a total of 559,544 cattle were bred in Bulgaria . The total number of dairy cows decreased by 5.2% year-on-year to 197,996.
