Longer summers, milder winters, more extreme weather and other environmental changes are intensifying infectious diseases and leading to new threats. These changes make it easier for mosquitoes, ticks, animals and the diseases they can carry to spread into new regions and infect more people.
Significant adverse health impacts of climate change are already occurring and are expected to worsen. The consensus of climate scientists is that these changes are the result of human activity. IDSA recognizes climate change and its impacts as a public health emergency in the United States and around the world. The Society is an active member of the Medical Society Consortium on Climate and Health.
