Understanding the Important Link Between Hosts and Diseases

Understanding the relationship between hosts and diseases is crucial for disease management. For example, the decline in sea ice in Arctic regions increases the risk of polar bears being exposed to flea-spread Bartonella bacteria, which are transmitted by nest fleas. Climate change is also expected to increase the prevalence of this bacterium, which causes tularemia, rabbit fever, and other diseases. Developing a better understanding of how these organisms and hosts are linked will help us anticipate and manage threats to humans.
