Dengue Warning Signs Checker
Tick the symptoms you have. The checker sorts them into emergency warning signs and milder dengue-like symptoms, then tells you what to do next.
Not a diagnosis. This tool is for guidance only. Dengue can become serious quickly — when in doubt, see a doctor.

Tests doctors usually order
- CBC (complete blood count) — watches platelet count and hematocrit.
- NS1 antigen test — detects dengue in the first 1–5 days of fever.
- Dengue IgM / IgG — antibody tests used after the first few days.
