SARS-CoV-2 Genetic Study of Environmental Samples Links Pandemic to Wuhan Market, Wild Animal Trade
A series of genetic and geospatial analyses of environmental samples collected at the Huanan market in Wuhan in 2020 linked early SARS-CoV-2 spread to the wild animal trade.
Dengue Virus Study IDs Mutation Linked to Attenuated Disease
Researchers identified a single amino acid change in a dengue virus type 2 strain from Tonga that led to reduced viremia in mammalian cells.
Genomic Study Finds Bird Flu Transmission Between Dairy Cattle, to Other Mammals
With genomic, phylogenetic, and epidemiological clues, researchers identified cow-to-cow transmission of highly pathogenic avian influenza H5N1 viruses.
Measles Virus Mutations Found to Drive Rare Lethal Brain Infection
Researchers turned to deep genome sequencing on brain autopsy samples to understand measles virus features involved in a rare, usually deadly form of encephalitis.
SARS-CoV-2 Genomes, Mobility Patterns Point to Broad Interconnections in COVID-19 Spread
A San Diego and Baja California-centered genomic surveillance study suggested local viral circulation accounted for just half of COVID-19 cases during the first five pandemic waves.
