Dengue in Singapore: What the NEA Data Means for Your Home
22 October 20267 min read
Quick answer: NEA's data shows dengue in Singapore swings sharply from year to year, peaks traditionally from May to October, and is driven by Aedes mosquitoes breeding in ordinary household containers. In NEA's April to June 2026 surveillance report, the top breeding habitats found in homes were pails, flowerpots, flowerpot plates, vases and refuse bins outside landed houses. A weekly check of those few items does more to protect your home than anything else.
Dengue numbers in Singapore make headlines when they spike and vanish from the news when they fall. Behind the headlines, NEA publishes a steady stream of data on cases, clusters and where mosquitoes are found breeding. This article pulls out the figures that matter to a household and turns them into a cleaning routine. For the step-by-step prevention basics, our existing guide to dengue prevention through home cleaning covers NEA's B-L-O-C-K steps in detail; here we focus on what the numbers say.
How many dengue cases has Singapore had recently?
The short version: very high in 2024, a sharp drop in 2025, and lower again so far in 2026.
| Period | Reported dengue cases | Source |
|---|---|---|
| 2024 (full year) | 13,651 | NEA figures as reported by The Straits Times |
| 2025 (full year) | 4,036, the lowest since 2018 | Ministry of Sustainability and the Environment, parliamentary reply, January 2026 |
| April to June 2026 | 770, up 87.8% on the previous quarter | NEA quarterly dengue surveillance report |
| 2026, first 42 epidemiological weeks | 2,764 | NEA dengue cases page |
According to the Ministry of Sustainability and the Environment's January 2026 parliamentary reply, the 2025 fall was put down to the absence of a major local outbreak, a global decline in dengue that year, and joint efforts by agencies and residents to control the mosquito population. The same reply said Project Wolbachia releases were set to cover 800,000 households, about half of all households in Singapore, by the end of 2026.
Two cautions. First, a low year does not mean the risk has gone. NEA's dengue cases page still listed 61 cases in the week ending 24 October 2026, with active clusters, several of them under red alert. Second, the virus serotype matters. NEA's April to June 2026 report found that DEN-3 made up the majority of typed samples, a shift from earlier in the year when DEN-2 dominated. Changes in the dominant serotype have historically been a warning sign, because fewer people have immunity to the newly dominant strain.
When is dengue season in Singapore?
NEA describes May to October as the traditional peak dengue season. Warmer temperatures speed up both mosquito development and the multiplication of the virus inside the mosquito, so the same number of breeding spots produces more risk in the hotter months.
That does not make the rest of the year safe. Breeding happens whenever water sits still, and the wet months of the northeast monsoon fill up every pail and saucer left outdoors. The sensible approach is a year-round weekly habit, stepped up from May to October and whenever there is a cluster near you.
Where are mosquitoes breeding in Singapore homes?
This is the most useful part of NEA's data for a household. NEA's dengue surveillance report for April to June 2026 lists the top five breeding habitats found in homes:
- Domestic containers, mainly pails
- Flowerpots
- Flowerpot plates
- Ornamental containers, such as vases
- Refuse bins placed outside landed houses
The same report notes that NEA detected over 4,000 mosquito breeding habitats across homes and public areas in that quarter, about 110% more than the quarter before. In public areas, the top spots were covered perimeter drains, discarded receptacles, gully traps, corridor scupper drains and covered carpark drains. Those are mostly the responsibility of town councils and building managers, but the home list is entirely within your control.
What stands out is how ordinary the home list is. These are not exotic hiding places. They are the mop pail in the service yard, the plant on the balcony, the vase on the dining table.
Turning the data into a weekly cleaning routine
Match each habitat on NEA's list to a specific action and a place in your week:
| NEA top home habitat | Where it usually is | Weekly action |
|---|---|---|
| Pails and buckets | Service yard, toilet, under the sink | Empty, wipe the inner rim, store upside down |
| Flowerpots | Balcony, corridor, window ledge | Loosen hardened soil so water drains through |
| Flowerpot plates | Under every pot | Lift, tip out, wipe dry; remove plates you don't need |
| Vases | Living and dining areas | Change water every few days and scrub the inside |
| Refuse bins outside landed homes | Gate and driveway | Keep lids closed, tip out rainwater, store off the ground |
A few other spots are worth adding even though they did not make NEA's top five for the quarter: the dish rack drip tray, pet water bowls, floor traps in rarely used bathrooms and the bamboo pole holders outside many HDB service yard windows.
Wiping the rim matters as much as tipping out the water. Aedes mosquitoes lay eggs on the inner wall of a container just above the waterline, and those eggs can survive drying out for a long time. Emptying a pail without wiping it leaves them ready to hatch the next time it fills.
How regular cleaning helps, and where it stops
A home that is cleaned on a schedule naturally gets these checks done. A cleaner emptying the mop pail, drying the dish rack tray and wiping down the service yard is removing the exact habitats at the top of NEA's list. If you have a weekly or fortnightly cleaner, it is worth adding "tip out and overturn all pails and saucers" to the standing instructions, so it happens every visit without you having to remember. Our guides to service yard and laundry area cleaning and balcony cleaning cover those two hotspots.
There are limits. We do not provide fogging, pest control or mosquito treatments; those need a licensed pest control operator. We also do not work on roof gutters or anything at an unsafe height.

Frequently asked questions
What are the most common places Aedes mosquitoes breed in Singapore homes?
In NEA's April to June 2026 report, the top five home habitats were pails, flowerpots, flowerpot plates, vases and refuse bins placed outside landed houses. All of them can be dealt with in a few minutes a week.
Is dengue still a risk in Singapore if case numbers are low?
Yes. Cases fell sharply in 2025, but NEA was still reporting weekly cases and active clusters in October 2026, and a shift in the dominant serotype can push numbers up again. The weekly check is worth keeping up regardless of the headlines.
When is the peak dengue season in Singapore?
NEA describes May to October as the traditional peak season, because warmer weather speeds up mosquito breeding and virus multiplication. Breeding can still happen at any time of year wherever water is left standing.
Can my part-time cleaner help with dengue prevention?
A cleaner can empty and overturn pails, dry trays, change vase water and keep the service yard and balcony clear, which removes the most common home habitats. Fogging and pest control need a licensed pest control company.
Want the weekly checks done without having to remember them? A weekly or fortnightly cleaning plan at $23/hr keeps the service yard, balcony and kitchen in order, and we do our best to send the same cleaner who knows your routine. WhatsApp +65 8166 0891 to set one up.
