Singapore recorded 71 dengue cases in the week ending 3 October, 11 fewer than the week before, but two red-alert clusters were still open as of 5 October, including an 88-case cluster at Ho Ching Road and Kang Ching Road, the National Environment Agency (NEA) said.
The other red cluster, which means 10 or more cases, is at Bishan Street 12, with 10 cases. NEA counted 12 active clusters in all. The traditional peak dengue season runs from May to October, and NEA is urging households to remove stagnant water at home.
The numbers behind the dip
Weekly cases have stayed in a narrow band across the six full weeks in NEA’s latest table. NEA’s table shows 88 cases in the week of 23 to 29 August, then 87, 73, 74 and 82, before the drop to 71. A further 34 cases were reported in the first four days of the current week, from 4 to 7 October.
Daily counts swing more. There were 15 cases on 6 October and one by 11am on 7 October. NEA says weekly numbers are a better guide to the trend than daily ones, because daily figures depend on how many cases are notified each day. Across the first 39 weeks of 2026, Singapore has recorded 2,564 cases.
At the cluster areas, NEA says it is spraying insecticide at homes and common areas, treating common areas with larvicide and fogging to kill adult mosquitoes.
Five checks around the flat
NEA’s household routine is called B-L-O-C-K, and each letter is one spot in the home:
- Break up hardened soil in plant pots.
- Lift and empty flowerpot plates.
- Overturn pails and wipe their rims.
- Change the water in vases.
- Keep roof gutters clear and place BTI insecticide inside.
NEA’s Check and Protect checklist adds a few more spots around the home. Bamboo pole holders should be capped. Kitchen dish racks and drying trays should be wiped dry. Pails not in use should be turned over, and any decorative container or fountain should have its water tipped out, changed and its surfaces scrubbed.
When someone at home is unwell
Households in cluster areas, and anyone diagnosed with or suspected to have dengue, should follow S-A-W, NEA says: spray insecticide in dark corners around the house, apply insect repellent regularly, and wear long-sleeved tops and long pants. NEA says preventing bites is how the disease is kept from spreading to more mosquitoes and people.
NEA advises anyone with symptoms that suggest dengue to see a doctor early.
If an NEA officer knocks
NEA is asking residents to let its officers inspect homes and spray insecticide. Officers carry an NEA Authority Card, enter only with the occupant’s consent, and ask a resident to accompany them throughout. Their identity can be checked at nea.gov.sg/validate-officer or on 6225 5632.
If an officer finds larvae or pupae, residents should not pour the water away. The officer collects a sample in a vial, seals it in front of the occupant and sends it for testing, and asks for identification, because breeding mosquitoes is an offence. NEA does not collect fines on the spot.
Under the Control of Vectors and Pesticides Act, premises found with mosquito breeding can draw a fine of up to S$5,000, up to three months’ jail, or both. For homes, NEA says the fine may come as a Notice to Attend Court, and owners or occupiers are told by mail if it takes enforcement action.
