- 2Climate change may worsen rodent-borne disease risks▼Changing climate may influence risks from deadly rodent-borne diseases
New reporting from researchers, including work covered by the Natural History Museum and Phys.org, suggests shifting climate conditions could change the risks humans face from deadly rodent-borne diseases. Changes in temperature and rainfall may alter rodent habitats and populations, potentially bringing infected animals into closer contact with people and expanding where diseases like hantavirus and Lassa fever pose a threat.
