Climate Change Ignites Global Infectious Disease Alarm

“Clinicians need to be ready to deal with the changes in the infectious disease landscape,” said lead author George R. Thompson. Thompson is a professor at the UC Davis School of Medicine in the Department of Internal Medicine, Division of Infectious Diseases, and the Department of Medical Microbiology and Immunology. “Learning about the connection between climate change and disease behavior can help guide diagnoses, treatment, and prevention of infectious diseases.

Changing rain patterns are expanding vectors’ range and their active periods. Shorter, warmer winters and longer summers are also linked to more vector-borne diseases. For example, diseases caused by ticks are now occurring in the winter too. They’re also being found in regions farther west and north than in the past.

“As an infectious disease clinician, one of the scariest things that happened last summer was the locally acquired cases of malaria. We saw cases in Texas and Florida and then all the way north in Maryland, which was really surprising. They happened to people who didn’t travel outside the U.S.,” Phillips said.Zoonotic diseases, such as plague and hantavirus , are also showing changes in incidence and location. The experts noted changes in animal migration patterns and natural ranges.

Global GDP Loss from Climate Change to Increase Exponentially, Study FindsA new study led by UCL researchers reveals that global GDP loss from climate change will increase exponentially as the planet gets warmer, especially when considering its impact on global supply chains. The study highlights the previously unquantified disruptions in supply chains that will further worsen the economic losses caused by climate change. The projected net economic loss by 2060 is estimated to be between $3.75 trillion and $24.7 trillion, depending on carbon dioxide emissions.
