Genome sequencing reveals widespread COVID-19 infection in white-tailed deer

Houston Methodist’s SARS-CoV-2 genome sequencing team has partnered on a study led by Penn State that revealed 80% of white-tailed deer sampled across Iowa at the height of the 2020-2021 deer-hunting season tested positive for the SARS-CoV-2 virus. Analysis of the virus genome sequences revealed infections were likely the result of multiple human-to-deer transmission “spillover” events followed by deer-to-deer transmission from April 2020 through January 2021.
