Discovery of coronavirus infections in white-tailed deer can help predict or prevent the emergence of novel variants.
Problem
Can we prevent potential spillback of SARS-CoV-2 from wild animals to humans?
- The global spread of SARS-CoV-2 (the virus that causes COVID-19 in humans) poses risks for spillover transmission to nonhuman hosts, which could in turn act as reservoirs for the virus, and potentially "spillback" to human hosts.
Findings
A team of researchers reported the first direct evidence of SARS-CoV-2 virus in any free-living species when they discovered that more than 80 percent of the white-tailed deer sampled in different parts of Iowa between December 2020 and January 2021 tested positive for the virus.
- The team examined nearly 300 samples collected as a part of a routine health surveillance program in Iowa, finding several different SARS-CoV-2 lineages circulating within geographically confined herds. This research suggested the occurrence of multiple independent spillover events from humans to deer, followed by local deer-to-deer transmission.
Impact
This discovery highlights the urgent need to support and sustain a robust and proactive "one health" approach that includes surveillance programs to monitor the spread of SARS-CoV-2 within deer and other susceptible wildlife species in the battle against the long-term persistence and evolution of this coronavirus.
- A better understanding of the ecology, molecular evolution, and spread of SARS-CoV-2 will help scientists and public health officials to predict and even prevent the emergence of future infectious diseases with pandemic and spillover potential.
