In dengue surveillance, the 'warning signs' that indicate possible severe dengue and require inpatient observation include all EXCEPT:

• A Abdominal pain or tenderness
• B Persistent vomiting
• C Tourniquet test positive (≥10 petechiae per square inch) ✓
• D Mucosal bleeding

Explanation

WHO 2009 dengue classification defines warning signs that predict progression to severe dengue: abdominal pain/tenderness, persistent vomiting, clinical fluid accumulation (ascites, pleural effusion), mucosal bleeding, lethargy/restlessness, liver enlargement >2 cm, and rising haematocrit with rapid platelet decline. A positive tourniquet test (≥10-20 petechiae/sq inch, Rumpel-Leede sign) is a diagnostic criterion for dengue fever and indicates increased capillary fragility, but it is not listed as a dengue 'warning sign' per the 2009 WHO classification. It guides diagnosis, not severity stratification.
