Health issues burning up in the face of heatwave

AS Malaysia grapples with a heatwave, the urgency to adapt and respond to the ensuing health challenges has never been more critical.

The Malaysian Meteorological Department’s (Metmalaysia) recent warnings of extreme temperatures sweeping across the nation highlight the delicate balance between nature’s forces and humanity’s endurance.

While Malaysians are, of course, accustomed to our tropical weather, we might not be as familiar with these increased temperatures caused by a combination of the current El Nino weather cycle and climate change.

It’s easy to ignore the temperature as business as usual and succumb to heatstroke, which can be especially fatal for young children and senior citizens.

That’s why it’s important to heed temperature alerts from

Metmalaysia and advice from health authorities to keep under shade and always, always stay hydrated.

But as we gulp water and take solace in the hum of air conditioners, another silent but equally formidable threat looms in the heat: the surge in dengue cases.

As of March 9, 35,619 dengue cases had been reported. Last year, over the same period, there were 21,602 cases.

The scorching heat and the almost 65% surge in dengue are no coincidence.

The Aedes mosquito that carries the dengue virus thrives in warm climates, its breeding cycle accelerated by higher temperatures.

Together with the intermittent rain that creates pools of stagnant water, it makes Malaysia an ideal breeding ground for Aedes aegypti.

This situation demands immediate and sustained action.

The government and health officials have been vigilant, issuing advisories and implementing measures to curb the spread of dengue. But the fight against this viral menace is not the government’s alone to wage: It is a battle that calls on every Malaysian to step up to the front lines.

Preventing dengue begins at home. Simple actions such as ensuring there are no pools of stagnant water anywhere, keeping water storage containers closed and using insecticides can significantly disrupt the breeding cycle of dengue-carrying mosquitoes.

Public spaces and communal areas must also be scrutinised for potential breeding spots.

Local authorities and community leaders should organise gotong-royong initiatives, focusing on clearing drains and gutters, often overlooked havens for mosquito larvae.

Personal protection is equally crucial. Using mosquito repellent, wearing light-coloured clothes and installing screens on windows and doors can provide an additional layer of defence against mosquito bites.

The peak biting times for the Aedes mosquito are early morning and late afternoon, so outdoor activities should be planned accordingly to minimise exposure.

This is a problem that Malaysia has been struggling with for decades, seemingly without much success, and that could be due to public apathy.

We’re accustomed to letting the government take care of matters with fogging and other such measures.

But the role of community awareness cannot be overstated. Public health campaigns should focus on educating the rakyat on the role we can play alongside providing information on things like signs and symptoms of dengue – fever, severe headache, pain behind the eyes, joint and muscle pain and a rash – and the importance of early medical intervention if infection is suspected.

As the nation navigates these trying times, that Covid-19-triggered spirit of “Kita Jaga Kita” (we take care of each other) has never been more pertinent.

Let’s remind each other to protect ourselves from the heat as well as dengue through vigilance, preparedness and community awareness.
