The paper analyzes the spread of H5N1 B3.13 in U.S. dairy cattle using genomic data and movement networks, finding that cattle movement, not birds, drives the outbreak.

This study shows H5N5 viruses have been repeatedly introduced across the Atlantic by high latitude seabirds, with more frequent introductions in fall and spring, and a distinct ecology from H5N1.

This study analyzes the genomic evolution and zoonotic potential of swine-origin influenza A viruses in Spain, identifying novel reassortants and highlighting human-swine viral transmission.

The paper reports the first known outbreak of H9N2 avian influenza in lesser rhea in Peru, identifies the virus as low pathogenic North American strain, and finds mutations potentially linked to increased virulence and host adaptation.

The paper identifies the emergence of D1.1 reassortant H5N1 viruses in North America, which show increased transmissibility, host range, and human spillover potential.

This study tracks the emergence and molecular evolution of H5N1 influenza viruses in U.S. dairy cattle, identifying increased mutation rates and positive selection after spillover from birds.

This study tracks the spread and evolution of H5N1 in the sub-Antarctic and Antarctica, revealing long-distance dispersal and mammalian-adaptive mutations.

Genomic sequencing identified a novel triple-reassortant H5N1 virus in Argentina, highlighting ongoing evolution of clade 2.3.4.4b in the Americas.

The paper reports a massive H5N1 outbreak in elephant seals and documents evidence for mammal-to-mammal transmission and spillover to birds.

The paper reports the genomic characterization of HPAI/H5N1 viruses in marine mammals and seabirds in Peru, identifying reassortant lineages and novel mutations.

The paper detects SARS-CoV-2 infection in a significant proportion of free-ranging white-tailed deer, suggesting a potential new natural reservoir for the virus.

January 2020 cases in Germany and Washington State were contained, while separate later introductions from China seeded the first sustained SARS-CoV-2 transmission networks in Italy and Washington State.
