A new study has revealed that dogs and cats can be infected with the Alpha variant of SARS-CoV-2, which was first identified in the United Kingdom, according to Science Daily.

The Alpha variant, also called B.1.1.7., rapidly outcompeted pre-existing variants in England because of its increased transmissibility and infectivity.

The study, published in the medical journal Veterinary Record, described the first identification of the Alpha variant in domestic pets – two cats and one dog – were positive on PCR test.

In addition, two cats and one dog displayed antibodies two to six weeks after they developed signs of cardiac disease.

Researchers found that many owners of these pets had developed respiratory illness a few weeks before their pets became ill and had also tested positive for COVID-19.

Furthermore, the study found that all of the pets had an acute onset of cardiac disease, including myocarditis (inflammation of the heart muscle).

Lead author of the study Dr. Luca Ferasin said, “Our study reports the first cases of cats and dogs affected by the COVID-19 alpha variant and highlights, more than ever, the risk that companion animals can become infected with SARS-CoV-2.”

“We also reported the atypical clinical manifestations characterized by severe heart abnormalities,” he added, “which is a well-recognized complication in people affected by COVID-19 but has never described in pets before.”

“However, COVID-19 infection in pets remains a relatively rare condition and, based on our observations, it seems that the transmission occurs from humans to pets, rather than vice versa,” explained Dr. Ferasin of The Ralph Veterinary Referral Centre, UK.
