Thanks For The Diarrhea Climate Change.

Pepto Bismol family of products.Led by Kathleen Alexander, an associate professor of wildlife at Virginia Tech’s College of Natural Resources and Environment, a team of researchers studying arid Botswanna have found a surprising link between the spread of diarrhea and dry weather:

“Many experts say contaminated water is a principal cause of the spread of diarrheal disease. The WHO says it “mostly results from contaminated food and water sources. Worldwide, around one billion people lack access to improved water and 2.5 billion have no access to basic sanitation.”

Yet the researchers’ findings indicated that water was only one of several factors to consider. “Our analysis suggests that forecast climate change increases in temperature and decreases in precipitation for the region are likely to increase dry season diarrheal disease incidence, while incidence in the wet season is likely to decline,” Alexander said.

Diarrheal case incidence peaks in both seasons in Botswana, with cases 20 percent more frequent on average in the dry than the wet season.”

Just what we’re not looking forward to: a warmer, drier, and stinkier future. [The Daily Climate via Grist]
