  Abstract Zoonotic spillover of influenza A viruses into humans has repeatedly triggered pandemics throughout history. Since their emergence in the 1990s, H5N1 influenza viruses have significantly expanded their geographical range and host species , raising global concern about the potential for sustained human-to-human transmission . In this review , we examine the virological characteristics of currently circulating H5N1 strains, key molecular barriers limiting their spread among humans, and critical areas of future research to mitigate the ongoing H5N1 panzootic and prevent future pandemics.

  Editor’s summary Birds operate at body temperatures several degrees higher than those of mammals, and, like mammals, birds are infected by influenza viruses. Influenza viruses can move between animal hosts, often reassorting their gene segments as they transition. Knowing that the body temperature of humans often elevates when sick, Turnbull et al. investigated whether virus gene segments originating from hot-blooded birds may give the virus an advantage in feverish mammals. They found that a viral polymerase containing an avian origin PB1 subunit indeed allowed the virus to replicate at higher temperatures in vitro and in a hyperthermic mouse model. —Caroline Ash Structured Abstract INTRODUCTION Influenza A viruses circulate in diverse species of birds and periodically spill over to cause severe or fatal infections in humans . Avian influenza A viruses are adapted to replicate in the gastrointestinal tract of birds at ~40° to 42°C . By contrast, human-adapted seasonal influenza ...

  Abstract Understanding the geographic spread of emerging respiratory viruses is critical for pandemic preparedness , yet the early spatiotemporal dynamics of the 2009 H1N1 pandemic influenza and SARS-CoV-2 in the United States (US) remain unclear . While mobility and genomic data have revealed important aspects of pandemic spatial spread, several key questions remain: Did the two pandemics follow similar spatial transmission routes? How rapidly did they spread across the US? What role did stochastic processes play in early spatial transmission? To address these questions, we integrated high-resolution disease data with a robust, data-efficient inference framework combining air travel, commuting flows, and pathogen superspreading potentials to reconstruct their spatial spread across US metropolitan areas . The two pandemics exhibited distinct transmission pathways across locations; however, both pandemics established local circulation in most metropolitan areas within weeks , driv...
