Increased infectious disease risk likely from climate change
Climate change will result in thousands of new viruses spread among animal species by 2070 — and that’s likely to increase the risk of emerging infectious diseases jumping from animals to humans, according to a new study.
This is especially true for Africa and Asia, continents that have been hotspots for deadly disease spread from humans to animals or vice versa over the last several decades, including the flu, HIV, Ebola and .
Researchers, who published their findings Thursday in the journal , used a model to examine how over 3,000 mammal species might migrate and and share viruses over the next 50 years if the world warms by 2 degrees Celsius (3.6 degrees Fahrenheit), which shows is possible.
They found that cross-species virus spread will happen over 4,000 times among mammals alone. Birds and marine animals weren’t included in the study.
Researchers said not all viruses will spread to humans or the scale of the coronavirus but the number of cross-species viruses increases the risk of spread to humans.
The study highlights two global crises — climate change and infectious disease spread — as the world grapples with what to do about both.
