Giuseppe Michieli#Update: First locally acquired #human case of #H7N7 #influenza A was detected in #Taiwan (CDC, May 5 '26), https://etidiohnew.blogspot.com/2026/05/update-first-locally-acquired-human.html
''Further analysis showed that the virus's #PB2 gene carries the E627K mutation (PB2 E627K).'' {indicating mammalian adaptation during human infection}.
Historical #Pandemic and Contemporary #Influenza A Viruses Reveal #PB2 M631L as a Convergent #Adaptation to #Human ANP32, https://etidiohnew.blogspot.com/2026/04/historical-pandemic-and-contemporary.html
''Of the nine D1.1 #infections in #humans, three viruses acquired #PB2 #mammalian #adaptations: D701N in A/Nevada/10/2025 and E627K in A/Wyoming/01/2025 and A/British Columbia/PHL-2032/2024''
