The study projects increasing spread over the next five decades of wildlife diseases caused by bacteria, fungi, viruses and infectious worms. There are serious implications for humans, said co-author Jason Rohr of the University of Notre Dame, Indiana.

“We do know that 75% of emerging infectious diseases have a wildlife origin,” said Rohr, who runs an ecology and public health lab at Notre Dame. “We should be concerned for our own health when we see studies suggesting that there could be increases in infectious disease in wildlife.”
