Sri Lanka's national dengue-control authorities have released their high-risk Grama Niladhari (GN) divisions for June 2026 — the areas being prioritised for intensified dengue-control activity. The list covers 14 districts, and Gampaha is one of them. Several of the flagged divisions fall directly inside the area St. Luke's Medical Laboratory serves.
If you live or work in one of the divisions below, this is the month to take dengue seriously: clear standing water around your home, watch for the warning signs, and get tested early if a fever starts.
Which St. Luke's-area divisions are on the June 2026 high-risk list
These GN divisions inside our home towns have been named for intensified dengue control this month.
Ja-Ela
Kapuwaththa · Indivitiya · Dandugama · Hapugoda East · Uswaththa
Wattala
Welikadamulla · Kerawalapitiya · Hekitha · Palliyawatta North · Balagalla
Ragama
Podiveekubura · Peralanda · Ragama · Tewaththa
Also flagged in the surrounding corridor
The same June 2026 list flags GN divisions across nearby MOH areas you may travel through or live close to, including Kelaniya, Mahara, Seeduwa, Biyagama, Dompe, Katana, Negombo and Minuwangoda. If your neighbourhood borders any of these, treat your area as high-risk too.
Living in Kandana, Welisara, Batagama or Thudella? Your division isn't individually named on this particular list — but each of these towns sits right beside a flagged zone along the Negombo Road corridor. Mosquitoes don't read GN boundaries, so the same precautions apply.
What "high-risk" actually means
A high-risk designation doesn't mean an outbreak is guaranteed where you live. It means the conditions for dengue transmission — mosquito breeding sites, recent case clusters, population density and rainfall — are high enough that health teams are concentrating fogging, inspections and awareness work in these divisions. For residents, it's a signal to be a step more careful than usual: a fever you'd normally wait out deserves a same-day test in a high-risk month.
Dengue warning signs — when to get tested
Most dengue starts like an ordinary viral fever, which is exactly why early testing matters. Consider getting tested if you have a sudden high fever plus any of:
- Severe headache or pain behind the eyes
- Muscle, joint or bone aches ("breakbone" pain)
- Nausea, vomiting or loss of appetite
- A skin rash appearing a few days into the fever
- Unusual tiredness
Seek emergency care immediately — don't wait for a test — if you or a family member develops any of these warning signs, which usually appear as the fever settles (often days 3–7):
- Severe or worsening abdominal pain
- Persistent vomiting
- Bleeding from the gums or nose, or blood in vomit or stool
- Restlessness, drowsiness or confusion
- Cold, clammy skin or difficulty breathing
These can signal the dangerous phase of dengue and need a hospital, not a home remedy.
Which dengue test, and when
The right test depends on how many days you've had a fever. Here's what we offer at St. Luke's and when each one is most useful.
| Test | Best used | Price (LKR) |
|---|---|---|
| Dengue NS1 Antigen | Days 1–5 of fever — for early confirmation | 1,200 |
| Full Blood Count (FBC) | From day 1, and repeated to monitor the illness | 400 |
| Platelet Count | Daily monitoring once dengue is suspected/confirmed | 400 |
- NS1 Antigen detects the virus itself and is most reliable in the first few days of fever — the earlier you test, the more useful it is.
- A Full Blood Count helps your doctor read the bigger picture (white cells, packed cell volume, platelets) and is usually repeated over several days.
- A Platelet Count is the number doctors track most closely, because a falling platelet level is a key marker of how dengue is progressing.
A diagnosis is always made by your doctor, who'll choose and time the tests for your situation. Our job is to get you accurate results quickly so that decision can be made without delay.

Cut the risk around your home this week
Dengue mosquitoes (Aedes aegypti) breed in clean, still water close to homes. A 15-minute sweep makes a real difference:
- Empty and scrub anything that holds water — buckets, pots, plant trays, pet bowls, tyres, bottle caps.
- Clear blocked gutters and roof valleys after rain.
- Cover water-storage tanks and barrels tightly.
- Change water in flower vases and fridge drip-trays every few days.
- Wear repellent and long sleeves at dawn and dusk, when these mosquitoes bite most.

Frequently asked questions
Which dengue test should I get on the first day of fever? A Dengue NS1 Antigen test (LKR 1,200) is the most useful in the first 1–5 days, because it detects the virus itself. Your doctor may also order a Full Blood Count to establish a baseline.
How much does a dengue test cost at St. Luke's? Dengue NS1 Antigen is LKR 1,200, a Full Blood Count is LKR 400, and a Platelet Count is LKR 400. Every test price is published on our price list.
My GN division isn't on the high-risk list. Am I safe? Not on the list doesn't mean no risk — especially if you're near a flagged area along the Negombo Road corridor. The same precautions and the same early-testing advice apply.
Do you offer dengue testing at home? Yes. Our home blood collection service covers all seven towns we serve. Call 071 123 1954 to book a visit.
How often should platelets be checked? Once dengue is suspected or confirmed, doctors usually monitor platelets daily during the critical period. Follow the schedule your doctor gives you.
