Indonesia's worst wildfire season in 11 years is taking a serious toll on public health. Respiratory infections linked to hazardous wildfire smoke more than doubled in just over a week, with over 113,000 people now affected. More than 12.5 million people across seven provinces have been exposed to dangerous haze, prompting a major emergency health response.
Indonesia is grappling with its most intense wildfire season in over a decade, fueled by "super-El Niño" conditions driving extreme heat and drought. Fires raging across Sumatra and Borneo are now responsible for a third of global fire emissions — and the health toll is mounting fast.
Indonesia's health ministry reported that wildfire-related respiratory illnesses more than doubled in just over a week, with thousands of medical workers deployed and nearly a million masks distributed to affected communities. Neighboring Singapore and Malaysia are also feeling the effects, with transboundary haze pushing air quality into unhealthy ranges. Japan has stepped in with military helicopters to support water-bombing operations, and Malaysia has offered additional aerial firefighting assistance.
Why it matters: This crisis underscores how climate-driven disasters can rapidly overwhelm public health systems, with cross-border health and environmental consequences that demand coordinated regional and international responses.
