JAKARTA: Almost 900,000 Indonesians suffered from an acute respiratory infection this year as noxious smoke and ash from forest fires blanketed central and western parts of the archipelago.
South Sumatra province has been the worst-affected area with 291,807 sufferers, followed by Riau with 268,591 people, according to the National Disaster Mitigation Agency.
Serious cases were also found in Jambi, West, South and Central Kalimantan, it said.
The haze is still at alarming levels even after the number of hotspots from illegal burning in Indonesia dropped Friday once artificial rains in Dumai, Riau province, and Palangkaraya, Central Kalimantan, helped douse some of the fires.
The country has opened clinics and “oxygen house” at state hospitals to treat people suffering from respiratory illness and distributed masks to people in haze-affected areas.
Malaysia reported a 16% increase in people suffering from asthma this week, compared with the average over the past 10 weeks, while those suffering from conjunctivitis rose 25% in the same period, the country’s Health Ministry said Friday, citing data from 31 clinics.
The country gave out free N95 masks in states surrounding the capital, Kuala Lumpur.
Indonesia’s government said the nation’s timber and plantation industries showed a lack of commitment in preventing fires on their land as only about 22% of forestry business permit holders submitted mandatory reports on forest fire control.
The Council of Palm Oil Producing Countries defended the industry, saying oil palm plantations were generally not the source of burning.
Authorities have named more than 200 companies and farmers as responsible for starting the fires and sealed off their land holdings.

Kuala Lumpur’s air quality index was 180 and Kuching’s 168, levels deemed unhealthy for all, while Jakarta’s air is unhealthy for sensitive groups such as children and the elderly.
