Active dengue clusters
Loading NEA's latest cluster list.
Source: NEA via data.gov.sg.
NEA alert levels
A cluster forms when two or more cases have onset within 14 days and live or work within 150 m of each other.
Red
High-risk area with 10 or more cases.
Yellow
High-risk area with fewer than 10 cases.
Green
No new cases, under surveillance for the next 21 days.
The data.gov.sg feed lists active (red and yellow) clusters. Green areas are shown on NEA's own cluster map.
Mozzie Wipeout: B-L-O-C-K
NEA asks every household to do these steps at least once a week. Aedes mosquitoes can breed in clean, stagnant water as small as a 20-cent coin.
Break up hardened soil
Loosen the soil in plant pots.
Lift and empty flowerpot plates
Flip plates and trays regularly, or avoid using them.
Overturn pails and wipe their rims
Store empty containers upside down under shelter.
Change water in vases
Scrub the inside too: mosquito eggs cling to it.
Keep roof gutters clear and place BTI insecticide
Clear gutters and drains so they don't block.
To protect yourself, NEA advises spraying insecticide in dark corners around the house and applying insect repellent regularly, especially if you live in a dengue cluster. Repellents with DEET, picaridin or IR3535 as the active ingredient are effective and safe; follow the label on when to reapply.
How this works
Clusters come from the National Environment Agency's (NEA) Dengue Clusters dataset on data.gov.sg, which NEA updates daily with the boundary, locality and case count of every active cluster. The page shows when the dataset was last updated. NEA's own cluster page can be a day ahead of the data.gov.sg feed.
Search a postal code, street or block and the page finds it on OneMap (SLA), checks whether it falls inside a cluster's boundary, and measures the distance to the nearest edge of each cluster. A cluster forms when two or more dengue cases have onset within 14 days and live or work within 150 m of each other.
NEA's alert levels: Red is a high-risk area with 10 or more cases; Yellow is a high-risk area with fewer than 10 cases. The level here is worked out from the case count in the dataset. Green (no new cases, under surveillance for 21 days) is not in the feed.
Prevention follows NEA's Mozzie Wipeout, B-L-O-C-K, which NEA asks households to do at least once a week: Break up hardened soil, Lift and empty flowerpot plates, Overturn pails and wipe their rims, Change water in vases, and Keep roof gutters clear and place BTI insecticide.
FAQs
How do I know if I live in a dengue cluster?
Enter your postal code above. The page checks it against the boundary of every active NEA dengue cluster and tells you whether you are inside one, or how far away the nearest cluster is, with its case count and alert level.
What is a red dengue cluster?
A red alert cluster is a high-risk area with 10 or more dengue cases. A yellow alert cluster has fewer than 10 cases.
What should I do if I live in a dengue cluster?
Do NEA's 5-step B-L-O-C-K Mozzie Wipeout at home at least once a week, spray insecticide in dark corners, and apply insect repellent regularly. NEA says repellents with DEET, picaridin or IR3535 are effective and safe. If you feel unwell with a fever, see a doctor.
How often are dengue clusters updated?
NEA updates its dengue cluster data daily. This page shows the time the data.gov.sg dataset was last updated, and each cluster's own last update date.
