The spread of the COVID-19 virus in deer is not unique as reports have emerged that the virus has infected multiple species of animals globally, including farmed mink, companion animals such as cats and dogs and also some zoo animals.&nbsp;</p>

<p>A <a href="https://www.nature.com/articles/s41586-021-04353-x_reference.pdf">study published last month in Nature</a> sheds light upon the implications of the transfer of virus to other species.

<p>As per the findings of the study, white-tailed deer are frequently infected with SARS-CoV-2 viruses. It further highlighted that questions have been raised about the future trajectory of the virus and the control measures that have been adopted around the world to curb the spread.&nbsp;</p>

<p>As per the study, the potential establishment of a new reservoir of virus in white-tailed deer could open new pathways for evolution, transmission to other wildlife species.&nbsp;</p>

<p>It is a known fact that COVID-19 infection rates are high in a community or population. Therefore, it is alarming that over one-third of deer in our study were positive by PCR, as it suggests an active or recent infection during last winter's major wave.&nbsp;</p>
