A dengue cluster at Lentor Gardens and Tung Po Avenue has grown to 12 cases, making it the third red-alert cluster in Singapore alongside Bishan Street 12 and the Ho Ching Road area in Jurong West. Seven clusters were active on Friday (16 October), according to the National Environment Agency (NEA), with nine of the Lentor cases reported in the past two weeks.
Red is NEA’s alert level for a high-risk area with 10 or more cases. On 12 October, only the Bishan and Ho Ching Road clusters were at that level.
Cases rise again in the week to 10 October
NEA recorded 79 dengue cases in the week ending 10 October, eight more than the week before. Weekly totals have stayed between 71 and 87 since the end of August.
A further 49 cases were reported from 11 October to 11am on 16 October, with the highest daily count, 12, on 13 October. Singapore has recorded 2,643 cases in the first 40 weeks of 2026.
Where the red clusters are
The Lentor cluster covers Lentor Gardens, with 10 cases, and Tung Po Avenue, with two. A separate cluster at Lentor Central and the Lentor Modern development has three cases, and a second Lentor Gardens cluster has two.
The Bishan Street 12 cluster has 16 cases across eight blocks, from Block 106 to Block 118, with five reported in the past two weeks.
The largest cluster runs across Ho Ching Road, Kang Ching Road, Tah Ching Road and Yuan Ching Road. It has 95 cases since it started, four of them in the past two weeks. Lakeside Tower on Yuan Ching Road accounts for 24 cases, and Block 330 Tah Ching Road for 17.
The other two clusters have four cases each, one at Cantonment Road and Tanjong Pagar Plaza and the other at Lorong Ong Lye, Pillai Road and Upper Paya Lebar Road.
What NEA is asking households to do
NEA officers are spraying insecticide at homes and common areas in the cluster zones, larviciding common areas and fogging to kill adult mosquitoes. The agency has asked residents to let its officers inspect their homes and spray.
At home, NEA’s Mozzie Wipeout steps target the places Aedes mosquitoes breed:
- 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
For people living in cluster areas, or anyone diagnosed with or suspected to have dengue, NEA adds three steps to prevent bites: spray insecticide in dark corners of the home, apply insect repellent regularly, and wear long-sleeved tops and long pants. A person with dengue who is bitten can pass the virus to mosquitoes, which then infect others.
There are no Zika or chikungunya clusters in Singapore. Singapore is at the end of its traditional peak dengue season, which runs from May to October.
