  • Two out of fifteen dogs from households with confirmed human cases of COVID-19 in Hong Kong SAR were found to be infected
  • Both dogs had antibody responses detected using plaque reduction neutralization assays.
  • Viral genetic sequences of viruses from the two dogs were identical to the virus detected in the respective human cases.

  • It is unclear whether infected dogs can transmit the virus to other animals or back to humans.
