Peruvian Amazon Matsés Face Malaria and Hepatitis B Epidemic Amid Climate‑Driven Isolation

Mongabay reporters found the Matsés, an Indigenous group in the Peruvian Amazon, battling a surge of malaria and hepatitis B. The illnesses, new to the community, emerged after the Matsés first contacted outsiders in 1969, exposing them to pathogens they had no immunity against. Climate change and prolonged drought have worsened the situation: dry weather creates ideal breeding grounds for malaria‑carrying mosquitoes, while reduced river flow cuts off the Matsés’ only route to medical care. The community has travelled to the nearest city to petition the Peruvian government for assistance, but reports of state neglect persist. The epidemic underscores how environmental shifts can directly threaten the health of isolated populations and strain limited public health resources.
