Regional climate changes drive life-threatening zoonotic disease outbreaks


Outbreaks of polycystic echicnococcosis, a life-threatening zoonotic disease, are driven by regional climate changes, according to a study led by the Barcelona Institute for Global Health (ISGlobal), an institution supported by "la Caixa" Foundation. The findings, published in PNAS, provide evidence of the impact of climate on neglected tropical diseases in the Amazon region, with implications for other zoonoses.

Polycystic echinococcosis (PE) is a neglected life-threatening zoonosis caused by an intestinal worm (Echinococcus vogeli) endemic in neotropical forests such as the Amazon. Although treatable, the disease can be fatal for about 1 in 3 infected people if not diagnosed in time. The parasite normally lives in animal reservoirs but can be transmitted to humans who handle infected animals, particularly pacas (a large rodent that is usually hunted for food).
