Abstract Circulating bat coronaviruses present a significant pandemic threat, yet our  understanding of  their genetic diversity and evolutionary dynamics remains limited.  Over 3 years, we sampled  1,462 bats in Cambodia’s Steung Treng province,  identifying extensive and diverse  coronaviruses co-circulation. Using  metatranscriptomic and amplicon sequencing, we  generated 33 complete  sarbecovirus genomes, revealing novel lineages that cluster into four  distinct  groups, each associated with different Rhinolophus bat species. Our analysis  highlights rapid migration and recombination of sarbecovirus lineages over  short distances  and timescales. Of note, the receptor-binding domains of two novel  viral groups exhibit high  similarity to SARS-CoV-2, and pseudovirus assays  confirmed the ability of this spike protein  to mediate entry into cells expressing  human ACE2, suggesting a potentia...

Abstract After nearly a decade without reported human A/H5N1 infections , Cambodia faced a sudden resurgence with 16 cases between February 2023 and August 2024, all caused by A/H5 clade 2.3.2.1c viruses . Fourteen cases involved a novel reassortant A/H5N1 virus with gene segments from both clade 2.3.2.1c and clade 2.3.4.4b viruses. The emergence of this novel genotype underscores the persistent and ongoing threat of avian influenza in Southeast Asia . This study details the timeline and genomic epidemiology of these infections and related poultry outbreaks in Cambodia.
