Indonesia's 2026 Wildfire Season Is a Public Health Emergency
Forest and peatland fires burning across Indonesia have crossed from an environmental crisis into a full-scale public health emergency. As of mid-September 2026, the Health Ministry had recorded 113,336 acute respiratory infection cases in seven fire-affected provinces, a figure that more than doubled in just eight days, rising from 50,891 on September 1 to the current count by September 9. Children under five account for more than 20 percent of those cases, totaling 26,545 young patients.
The Jakarta Post, which first reported these details, cited Health Ministry spokesperson Widyawati confirming that around 12.5 million people across the affected regions have been impacted by the fires.
Where the Air Is Worst
Three regencies in Central Kalimantan are recording the most dangerous air quality in the country. East Kotawaringin scored 750 on the government's Air Pollutant Standard Index (ISPU), Katingan scored 629, and Gunung Mas reached 394. Any reading above 300 is classified as hazardous under the ISPU system, meaning all three regencies are well into territory considered severely harmful to human and animal health.
Central Kalimantan has been among the hardest-hit provinces this season. Independent forest monitoring platform Nusantara Atlas recorded approximately 68,300 hectares burned in the province between January and August, an area roughly the size of Jakarta. Nationally, the platform found close to 895,657 hectares burned across the country in the same period, a figure 34 percent higher than during the El Niño-affected season of 2019.
The El Niño climate pattern over the Pacific is intensifying dry conditions, and hot spot counts are still climbing. Nusantara Atlas detected 532,152 hot spots on September 13, up from 488,170 the previous day.
Government Response and Cross-Border Impact
The Health Ministry has placed 1,691 community health centers and 360 referral hospitals on standby, mobilizing more than 19,000 health workers. Masks, oxygen concentrators, gloves, and air purifiers are being distributed across affected provinces. West Kalimantan extended its provincial state of emergency through September 20 to allow faster deployment of funds and equipment.
On the firefighting side, the National Disaster Mitigation Agency has deployed nearly 44,000 personnel and 45 aircraft for patrols and waterbombing missions. Japan's Maritime Self-Defense Force vessel JS Kunisaki arrived in Mempawah, West Kalimantan, carrying three heavy transport helicopters and up to 300 personnel to assist with aerial firefighting.
The haze has crossed national borders. Cities in Sarawak, Malaysia recorded air quality readings of 200, rated unhealthy, while Singapore's reading stood at 122, still considered unhealthy for sensitive groups according to IQAir.
Health Ministry spokesperson Widyawati has advised people in affected areas to wear masks outdoors, monitor air quality indexes, stay hydrated, and seek medical attention immediately if breathing difficulties arise.
Why It Matters for Hosts
Independent accommodation and hospitality operators in Central Kalimantan, South Sumatra, West Kalimantan, and Jambi should treat this season as an active operational risk. Guests arriving from unaffected regions may be unprepared for hazardous air quality. Stocking N95 or equivalent masks, providing indoor air purifiers in guest rooms, and displaying the current local ISPU reading prominently at check-in are practical, low-cost steps that directly address guest safety. Operators should also keep the nearest Puskesmas address and referral hospital contact on hand for guests who develop symptoms. Proactive communication before arrival, letting guests know current conditions and what precautions are in place, builds trust and reduces last-minute cancellations driven by uncertainty.
