KUALA LUMPUR, Aug 12, 2026 — The Ministry of Health (MOH) has urged the public to take precautions against the haze after 10 air-quality monitoring stations recorded unhealthy Air Pollutant Index (API) readings as of 9am on Aug 11.

According to the Air Pollutant Index Management System (APIMS), nine affected areas were in Sarawak — Serian, Samarahan, Kuching, Bintulu, Samalaju, Mukah, Sibu, Sarikei and Sri Aman — while Johan Setia in Selangor was also affected.

No areas recorded API readings at the “Very Unhealthy” or “Hazardous” levels. However, the Sarawak State Disaster Management Committee (JPBNS) said 19 areas in the state had a high potential of being affected if open burning activities continued.

MOH advised members of the public, particularly those in affected areas, to reduce outdoor physical and strenuous activities when API readings exceed 100.

The ministry also recommended reducing time spent outdoors and wearing a suitable face mask when outdoor exposure is unavoidable. Residents should keep windows and doors closed to minimise the entry of polluted air and avoid activities that contribute to indoor air pollution, including smoking.

Motorists were advised to use the recirculation mode on their vehicle air-conditioning systems, while those who can afford it were encouraged to use air purifiers at home.

The public should also drink sufficient water and remain hydrated, while additional protection should be given to vulnerable groups such as children, senior citizens and people with chronic illnesses by limiting their exposure to haze.

MOH said individuals should seek medical attention promptly if they experience breathing difficulties, persistent coughing or other worsening symptoms.

Educational institutions, government agencies and private-sector organisations were also advised to monitor current API readings and adjust outdoor activities according to air-quality conditions. Sports, co-curricular programmes and strenuous outdoor activities should be postponed or moved indoors when API readings exceed 100.

The ministry further urged the public not to engage in open burning, which can worsen air quality and increase health risks associated with haze.

MOH said it had strengthened surveillance of haze-related illnesses at its healthcare facilities to monitor any increase in cases and detect changes in disease trends. Healthcare facilities had also enhanced their preparedness, including supplies of medicines and healthcare personnel, to ensure appropriate services remained available.

The ministry added that it would continue working with the Department of Environment and other federal and state agencies to monitor the situation and coordinate measures to reduce the impact of haze on public health.
