PETALING JAYA: The Health Ministry will strengthen systems linking environmental data with disease patterns and human behaviour to identify health risks earlier, before they affect the public.
The ministry said weather conditions, air quality, rainfall patterns, environmental conditions and vector data needed to be analysed alongside disease data to enable earlier detection of potential health threats.
“(This approach) will allow risks to be identified earlier, before the health of the people is affected,” it said in a statement issued in conjunction with the ministry-level 2026 World Environmental Health Day celebration.
The ministry said the event underscored that human health could not be separated from the health of the planet, in line with this year’s international theme, “Environmental Health: Standing with Science to Protect Communities”.
It said climate and environmental changes were increasingly affecting human health, raising the risk of disease, placing greater pressure on healthcare facilities and potentially altering the patterns of diseases such as zoonotic and vector-borne diseases.
They could also add to the challenges posed by antimicrobial resistance, it added.
“Human health, animal health and environmental health are closely interconnected. Changes in one component can affect the others,” said the ministry.
It cited dengue as one of the clearest examples in Malaysia, with changes in temperature, rainfall and humidity affecting the ecosystem of the Aedes mosquito.
However, the ministry stressed that dengue prevention was not solely the responsibility of the Health Ministry.
Prevention had to begin at ground level by eliminating breeding sites, ensuring there was no stagnant water and making communities part of the prevention system, it said.
The celebration also featured community initiatives involving the detection and cleaning of Aedes breeding sites, as well as the use of sticky ovitraps.
The ministry commended the communities involved, stressing that technology would only be meaningful when accompanied by changes in behaviour.
“When science reaches the community, the community can turn that science into action. The community is not merely a recipient of health interventions. The community is part of the early warning system and part of the solution,” it said.
The ministry said the shift was from a reactive approach towards one that was predictive and preventive.
It said the approach was also reflected in the development of healthcare facilities through its Environmentally Sustainable Healthcare initiative, which focuses on energy efficiency, indoor air quality, resource and waste management, and reducing carbon emissions.
“This is so that hospitals and clinics do not merely treat illnesses, but also become examples of healthy and climate-resilient environments,” it said.
As of 2025, 147 Health Ministry hospitals and institutions had obtained green certification, while 87 healthcare facilities had implemented the Penempatan Sejahtera approach in 2026.
The ministry is targeting 50% of healthcare facilities to adopt the approach by 2030.
It said the Institute for Medical Research had also produced a guide in 2026 to assess health vulnerability to climate change among small island communities, supporting the identification of vulnerable communities and evidence-based adaptation planning.
The ministry said it would continue strengthening surveillance of diseases sensitive to environmental and climate changes, including vector-borne diseases such as dengue and malaria, food- and water-borne diseases, as well as illnesses associated with haze and extreme heat.
“Environmental health is not merely about the environment. It is about people, about communities and, ultimately, about protecting the people,” it said.
“From research to action. From data to early warning. From prevention to protection.”
The ministry called on the Government, local authorities, academia, industry, communities and the public to work together as a whole-of-society ecosystem.
