A new study published in the journal npj Viruses found that climate change could drive rodent-borne arenaviruses into parts of South America that have never previously faced these diseases, with potential to expose millions more people to future spillover risk.
Researchers from UC Davis Weill School of Veterinary Medicine, including OHI's own Drs. Brian Bird and Marcy Uhart, collaborated to develop predictive models to better understand how these viruses may spread over the next 20-40 years.
This research highlights the importance of One Health approaches that recognize the deep connections between environmental change, wildlife, and human health.
Climate change is likely to drive rodent-borne arenaviruses into parts of South America that have never faced these diseases, putting new communities of people at risk, finds a study from the University of California, Davis. For the study, published in the journal npj Viruses, scientists incorporate...
