An epidemic of chronic kidney disease that has killed tens of thousands of agricultural workers worldwide, is just one of many ailments poised to strike as a result of climate change, according to researchers at the University of Colorado Anschutz Medical Campus.

"Chronic kidney disease is a sentinel disease in the era of climate change," said Cecilia Sorensen, MD, of the Colorado School of Public Health and the University of Colorado School of Medicine.

Sugar cane workers in Central America, who often toil in 104-degree heat in heavy clothing, are often victims of the illness. Sorensen said there is evidence that constant exposure to high temperatures can result in chronic kidney damage.

"They can't say it's too hot, they don't want to go work in the fields," she said. "If they don't work, they don't eat that night."

The disease is also showing up in the U.S. in places like Florida, California and Colorado's San Luis Valley.

And the hotter it gets, Sorensen said, the more likely it will increase along with other diseases.

"When it gets hotter, we see more people in emergency rooms with cardiovascular disease," said Sorensen, who is an emergency department physician at CU Anschutz and a member of the CU Consortium for Climate Change & Health. "We are seeing average global temperatures gradually creep up but one of the biggest risks are heat waves."

She said U.S. public health officials are not prepared for the kinds of heat waves seen in Europe in 2003 that killed over 70,000 people.

"We are way behind the curve on this compared to Europe," she said. "We are also seeing Lyme disease in places we never saw it before because the winters are no longer cold enough to kill off the ticks that carry it."

She said the mosquitos that carry diseases like Zika, dengue fever and Chikungunya are now showing up in the U.S.
