Malaysia has not yet recorded a significant increase in haze-related illness, but the Health Ministry says cases could rise if poor air quality continues or worsens.

Health facilities monitoring daily

The ministry is tracking upper respiratory tract infections, asthma and conjunctivitis through sentinel health facilities. It says there has been no significant increase in cases in any state compared with the period before the haze.

In Sarawak, 12 sentinel clinics recorded a fall in upper respiratory infections from 1,473 cases in epidemiological week 31 to 1,347 in week 32. Asthma cases fell from 195 to 122, while conjunctivitis rose from 15 to 43.

A total of 68 health facilities have been selected to monitor haze-related illness. Data collection has increased from weekly before the haze to daily during the current conditions.

Higher risks for vulnerable groups

The ministry says children, older people and those with chronic illness face greater risks. Fine haze particles can reach deep into the lungs, trigger inflammation and shortness of breath, and worsen asthma, chronic obstructive pulmonary disease and heart disease.

So far there has been no significant increase in haze-linked hospital admissions or emergency cases. Health facilities have been instructed to remain alert if the haze persists.

What it means for foreigners in Malaysia

Residents and visitors with asthma, heart disease or other chronic respiratory conditions should follow their doctor's advice, take regular medication and reduce time outdoors when air quality is poor. Families with young children should also limit exposure.

The ministry advises people to avoid outdoor exercise, stay indoors where possible, close windows, avoid smoking and use suitable masks if they need to go outside. Drivers are advised to use air conditioning in recirculation mode. Check local air-quality updates before outdoor travel or activities
