Indonesia wildfire respiratory cases surge past 175,000

How many people are affected by the respiratory crisis?

The Indonesian health ministry has recorded approximately 175,000 respiratory illness cases since August, marking a significant escalation in the public health emergency. The scale of the medical crisis is particularly acute among vulnerable populations, with more than 40,000 reported cases involving toddlers. These medical conditions range from mild symptoms like persistent coughs to severe respiratory ailments, including bronchitis and pneumonia.

The speed at which the illness is spreading is evident in the recent ministry data. Between 1 September and 9 September 2026, the number of people suffering from wildfire-related respiratory issues more than doubled, jumping from 50,891 to 113,336 cases. This rapid spike highlights the immediate impact of the toxic smog on the local population as the fire season progresses.

Impact on public infrastructure and daily life

The worsening air quality has forced significant disruptions to social and educational stability. Schools across various regions in Indonesia have been forced to close to protect students from inhaling hazardous particulate matter. Simultaneously, healthcare facilities have experienced a surge in admissions, straining the capacity of medical institutions to manage the influx of patients suffering from smoke-induced ailments.

Why are the wildfires more severe this year?

The severity of the current wildfire season is attributed to a powerful 'Godzilla' El Nino, which has created exceptionally dry conditions across the archipelago. While Indonesia typically faces a dry season from July through October, the extreme weather patterns this year have acted as a catalyst for more frequent and intense blazes. The combination of high temperatures and low humidity has made the landscape highly combustible.

Data from the independent forest monitoring platform Nusantara Atlas underscores the unprecedented nature of this season. As of late September 2026, the platform detected roughly 734,000 hotspots across Indonesia. This figure represents a significant increase in fire activity, standing more than 30% higher than the levels recorded during the 2019 wildfire season, which was previously considered one of the country's most devastating periods.

The scale of land destruction is also immense. Since January 2026, at least 895,657 hectares of land have been consumed by flames. To provide a sense of scale, this area is nearly six times the size of Greater London. The difficulty in containing these fires is compounded by the unique geography of the region, particularly the challenging peatland conditions which can sustain underground fires that are notoriously difficult to extinguish.

What measures are being taken to combat the fires?

The Indonesian government has mobilized a massive response involving both aerial and ground-based operations. More than 54,000 officials have been deployed to the islands of Borneo and Sumatra to manage the crisis. This deployment includes dozens of aircraft dedicated to water bombing missions aimed at suppressing the flames from above.

In addition to direct firefighting, the government has implemented cloud-seeding operations to induce rainfall. These operations involve the dispersal of substances such as salt crystals or silver iodide into existing clouds to encourage precipitation. This effort has seen international cooperation, with members of the Japan Self-Defense Forces arriving in Borneo earlier this month to assist in the firefighting efforts.

The debate over cloud-seeding effectiveness

Despite the large-scale implementation of cloud-seeding, its efficacy remains a subject of debate among meteorologists. While the technology is used to target specific areas, its ability to reliably extinguish massive, widespread wildfires is not universally accepted by scientific experts. The complexity of the atmospheric conditions during an El Nino event adds further uncertainty to the success of these weather manipulation attempts.

How is the haze affecting wildlife and the environment?

The toxic smog is causing significant mortality and distress among Indonesia's wildlife, including critically endangered species such as orangutans. The environmental degradation extends beyond the immediate loss of habitat, as the smoke and poor air quality impact the physiological health of animals in the affected regions.

A tragic example of this impact occurred in West Kalimantan, one of the provinces most severely affected by the fires. A wildlife foundation recently documented a case where an orangutan was found struggling on a palm oil plantation. Although the animal was rescued and treated for hypoxia—a condition caused by a lack of oxygen—it ultimately died. This incident serves as a stark indicator of the lethal impact the haze has on the region's biodiversity.

What are the legal and regional implications of the disaster?

The recurring nature of these wildfires has led to significant legal challenges against the Indonesian government. In West Kalimantan, indigenous and civil society groups have initiated a class action lawsuit against both central and local administrations. The plaintiffs allege deliberate negligence, arguing that the government failed to implement adequate preventative measures despite the predictable risks of the annual haze season.

Lawyer Glorio Sanen, representing the group, stated that the recurring pattern of these disasters proves that authorities were aware of the potential for haze and the associated risks but failed to act sufficiently to mitigate them.

The crisis is not contained within Indonesian borders; the haze has become a significant regional issue. Air quality has deteriorated in neighboring Malaysia and Singapore, prompting authorities in Singapore to issue daily haze advisories. The smog has even reached parts of the Philippines, where officials have advised residents to remain indoors. In the Malaysian state of Sarawak, authorities have also utilized cloud-seeding not just to fight the haze, but as a strategic measure to replenish declining water levels in hydropower dams before a predicted dry spell in October.

Frequently asked questions

How many people have been affected by respiratory issues in Indonesia?

Approximately 175,000 people in Indonesia have suffered from respiratory illnesses since August 2026. This includes more than 40,000 cases involving toddlers, with conditions ranging from coughs to severe pneumonia caused by the toxic wildfire smoke.

What is driving the intensity of the 2026 wildfires?

The intensity is primarily driven by a 'Godzilla' El Nino, which has caused extremely dry conditions across Indonesia. This has resulted in a 30% increase in hotspots compared to the severe 2019 fire season, according to Nusantara Atlas.

How much land has been burned so far this year?

Since January 2026, at least 895,657 hectares of land have been burned. This area is roughly six times the size of Greater London, highlighting the massive scale of the environmental destruction occurring across the archipelago.

Is the haze affecting other countries?

Yes, the haze has impacted Malaysia, Singapore, and parts of the Philippines. Singapore has issued daily haze advisories, while officials in the Philippines have urged residents to stay indoors to avoid the toxic smog.

What is being done to fight the fires?

Indonesia has deployed over 54,000 officials and dozens of jets for water bombing. Additionally, cloud-seeding operations are being conducted, sometimes with assistance from the Japan Self-Defense Forces, to encourage rainfall and suppress the fires.
