Official iDengue dengue hotspot localities across Malaysia. Each marker represents an outbreak persisting more than 30 days in a public locality; markers do not represent patient addresses.
On iDengue, a hotspot is an outbreak locality persisting for more than 30 days. The map uses the latest official locality points and outbreak-associated case totals published by MYSA and KKM.
The case number in a marker is the cumulative number linked to that listed outbreak. It is not the complete year-to-date total for everyone living in the locality or district.
If your locality appears on this map or is identified as a dengue hotspot by iDengue, take immediate action to eliminate standing water around your home. The complete life cycle from Aedes egg to adult mosquito takes approximately 7–10 days, so weekly inspection and destruction of breeding sites is essential to break the cycle before new mosquitoes emerge.
Focus on flowerpot saucers, roof gutters clogged with leaves, discarded containers, bathroom water storage, uncovered tanks, and any objects that can collect even small amounts of rainwater. A single bottle cap of stagnant water is sufficient for Aedes to lay eggs. For a comprehensive step-by-step prevention plan, read our complete dengue prevention guide.
Dengue warning signs: If you develop sudden high fever (40°C), severe headache, pain behind the eyes, joint and muscle pain, or skin rash — especially while living in or near a hotspot — seek medical attention immediately. Do not take aspirin or ibuprofen. Go to your nearest hospital emergency department or call Malaysia emergency services at 999. Early detection saves lives.
Elderly individuals, young children, pregnant women, and people with chronic conditions such as diabetes and hypertension are at significantly higher risk of developing severe dengue complications including dengue haemorrhagic fever and dengue shock syndrome. Families with elderly members living in or near hotspot areas should take extra precautions — our guide on protecting seniors during outbreak season covers specific measures for this vulnerable group.
Parents with children attending childcare centres or kindergartens in hotspot localities should confirm with the facility that outdoor play schedules have been adjusted to avoid peak Aedes biting hours (early morning and late afternoon), and that the premises are regularly inspected for breeding sites. Our childcare health and safety checklist covers what to look for.
Community action: Dengue prevention is most effective when entire neighbourhoods participate. Organise or join gotong-royong (community clean-up) activities to eliminate breeding sites across your area — a single untreated breeding site on a neighbour's property can produce mosquitoes that affect your entire street. Employers can find workplace-specific requirements in our workplace health and safety guide.
Hotspot points, locality names, districts, outbreak-associated cases, start dates and durations come from the latest public iDengue map snapshot. Locations identify general outbreak localities, not individual homes. The ArcGIS service is public-facing but undocumented, so the feed is validated and fails closed if its schema, date or record count changes unexpectedly.
