# Dengue Clusters Singapore: Is There One Near Me?

Check if your home or workplace is in or near an active dengue cluster, with NEA's latest case counts, red or yellow alert levels and the B-L-O-C-K steps.

## 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.
