As wildlife trade expands, so do pathways for disease spillover to humans
A new study found that mammals sold in the global wildlife trade are 50% more likely to share pathogens with humans than those not traded. The research highlights the need for stronger biosurveillance and a 'One Health' approach to mitigate the risk of disease spillover.
The global wildlife trade increases the risk of disease transmission between animals and humans. Researchers analyzed trade records of thousands of mammal species over 40 years and found that traded mammals are 50% more likely to share pathogens with humans. The study, published in the journal Science, highlights the need for stronger biosurveillance and a 'One Health' approach. The global wildlife trade, valued at $220 billion annually, creates opportunities for pathogens to jump between species. Repeated and prolonged human contact with traded animals may facilitate disease spillover. The research emphasizes the importance of considering risks to both animals and humans in addressing the wildlife trade.
