Outbreak of highly pathogenic avian influenza a(H5N1) among house cats: A case series involving oseltamivir treatment

Share:

Gomez et al. (2025) reported the following highlights from their work:

  • "We report a highly pathogenic avian influenza A(H5N1) outbreak among four domestic cats from the same household.
  • With early supportive care and antiviral treatment, H5N1 is survivable in domestic cats.
  • Survivor cats may maintain high titers of neutralizing antibodies against H5N1 at least 3-4 months post recovery."
