Extreme weather events can unleash a 'perfect storm' of infectious diseases, research study says

Climatic conditions can alter normal host-pathogen relationships
An international research team, including University of Minnesota researcher Craig Packer, has found the first clear example of how climate extremes, such as the increased frequency of droughts and floods expected with global warming, can create conditions in which diseases that are tolerated individually may converge and cause mass die-offs of livestock or wildlife.
