Researchers said not all viruses will spread to humans or become pandemics the scale of the coronavirus but the number of cross-species viruses increases the risk of spread to humans.
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 coronavirus.
Researchers, who published their findings Thursday in the journal Nature, 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 recent research 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.
