Malaysia records sharp spike in asthma cases as haze persists

Health Minister Dzulkefly Ahmad disclosed the alarming figures on respiratory health complications, attributing the increases to deteriorating air quality affecting the nation. The data revealed asthma cases have surged by 259 percent, while diagnoses of upper respiratory tract infections have climbed 124 percent during the haze period.

The sharp rise in respiratory ailments underscores the health risks associated with transboundary haze pollution, a recurring challenge for Malaysia and neighbouring countries in the region. Medical professionals have identified vulnerable populations including children, the elderly, and those with pre-existing respiratory conditions as particularly susceptible to complications from poor air quality.

The Health Ministry has advised the public to take preventive measures during haze episodes, including limiting outdoor activities, using air filtration systems indoors, and seeking medical attention for respiratory symptoms. Healthcare facilities have reportedly increased their capacity to manage the influx of patients presenting with respiratory complaints.

Authorities continue to monitor air quality indices and coordinate regional efforts to address the root causes of the haze crisis affecting public health across the region.
