While primarily considered a disease affecting birds, we have seen some evidence of H5N8 jumping to mammals (see https://afludiary.blogspot.com/2015/02/mafra-h5n8-antibodies-detected-in-south.html" style="margin: 0px; padding: 0px; border: 0px; font-size: 13px; font-family: inherit; vertical-align: baseline; color: rgb(35, 121, 181); text-decoration: none; - MAFRA: H5N8 Antibodies Detected In South Korean Dogs (Again) ), and some research (see https://afludiary.blogspot.com/2017/01/sci-rpts-h5n8-rapid-acquisition-of.html" style="margin: 0px; padding: 0px; border: 0px; font-size: 13px; font-family: inherit; vertical-align: baseline; color: rgb(35, 121, 181); text-decoration: none; - Sci Rpts: H5N8 - Rapid Acquisition of Virulence Markers After Serial Passage In Mice) suggesting that H5N8 might someday acquire the genetic changes that would make it a human health threat as well.
A 2017 editorial in the http://www.tandfonline.com/toc/kvir20/current" style="margin: 0px; padding: 0px; border: 0px; font-size: 13px; font-family: inherit; vertical-align: baseline; color: rgb(35, 121, 181); text-decoration: none; - Journal Virulence (see https://www.blogger.com/#" style="margin: 0px; padding: 0px; border: 0px; font-size: 13px; font-family: inherit; vertical-align: baseline; color: rgb(35, 121, 181); text-decoration: none; - J. Virulence Editorial: HPAI H5N8 - Should We Be Worried? ) reviewed and summarized the literature, and found enough reasons to be concerned over the future evolutionary path of H5N8, stating that: The extensive distribution of HPAI H5N8, as well as the gene reassortment with other circulating avian viruses already observed for H5N8 suggests there is a potential risk for human cases of H5N8 infections.
So, while the threat to humans posed today by H5N8 may be low or very low, there are no guarantees it will remain so. Viruses evolve, and while that evolution is unplanned and random - it can sometimes lead to dangerous species jumps - as we've seen demonstrated so vividly with SARS-CoV-2. - Although we have the original https://tass.ru/interviews/10884999" style="margin: 0px; padding: 0px; border: 0px; font-size: 13px; font-family: Helvetica, Arial, Verdana, sans-serif; vertical-align: baseline; color: rgb(35, 121, 181); text-decoration: none; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(235, 244, 249); - in Russian, the following English language summary comes from theMoscow Times. https://www.themoscowtimes.com/2021/03/12/russia-warns-of-h5n8-bird-flu-transmission-a73219" style="margin: 0px; padding: 0px; border: 0px; font-size: 13px; font-family: inherit; vertical-align: baseline; color: rgb(35, 121, 181); text-decoration: none; - The mutating H5N8 strain of avian flu has a high risk of human-to-human transmission, Russian authorities https://tass.ru/interviews/10884999" style="margin: 0px; padding: 0px; border: 0px; font-size: 13px; font-family: inherit; vertical-align: baseline; color: rgb(35, 121, 181); text-decoration: none; - Friday.
Anna Popova, who heads Russia’s health watchdog Rospotrebnadzor, made the prediction nearly a month after scientists detected the first case of H5N8 transmission to humans at a southern Russia poultry farm.
“There’s a fairly high degree of probability” of human-to-human transmission forecasts, Popova told the state-run TASS news agency.
Though people can get infected with other bird and swine flu subtypes, the H5N8 strain that is lethal for birds has never been reported to have spread to humans.
“This is likely to happen. Colleagues say that the mutation is continuing very actively,” Popova said.
