Some South American rodent-borne viruses may spread as climate warms

As climate change progresses, certain rodent-borne viruses, specifically arenaviruses and hantaviruses, may expand their reach in South America. Rodents that currently harbor these viruses could migrate into new regions where these pathogens pose no existing threat. This shift underscores the interconnectedness of climate dynamics and public health, emphasizing the need for enhanced surveillance and proactive measures. Understanding the potential spread of these viruses is crucial for protecting vulnerable populations and mitigating future health risks associated with climate-induced ecological changes.
