Sumary of Cats shed SARS-CoV-2 RNA for a shorter duration compared to humans, study finds:

  • Since the emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes the coronavirus disease 2019 (COVID-19), there have been numerous reports of pets becoming infected..
  • A new study by researchers at the University of Technology Sydney, the University of Sydney, the Icahn School of Medicine at Mount Sinai, New York, and the Universidad de Chile shows that infected cats have shorter shedding of SARS-CoV-2 RNA compared to their human owners..
  • The results highlight a need for large-scale epidemiological analysis of the SARS-CoV-2 infection dynamics to develop preventive measures in both humans and their pets..
  • In the current study, which appeared on the preprint server medRxiv*, the team conducted active surveillance in Santiago City, Chile, starting in May to determine the possibility of infection in companion animals in households where people tested positive for SARS-CoV-2..
  • The team described the infection in a household of two human adults and three cats using real-time reverse transcription-polymerase chain reaction (RT-PCR) tests and enzyme-linked immunosorbent assay (ELISA) tests, viral sequencing, and viral isolation..
  • Arrows with the corresponding caption colors indicate the day of symptom onset and the date of the SARS-CoV-2 diagnosis of humans..
  • All cats excreted detectable SARS-CoV-2 RNA for a shorter duration than humans, and the viral sequences confirmed the human to cat transmission…
