Following investigations will be done in both arms, full blood count (twice daily) Liver enzymes (daily) CRP (at least twice during hospital stay) Dengue serotypes Dengue IgG, IgM antibodies at day 5 or 6 TNF (once during the hospital stay) IL-6 (once during the hospital stay) Ultrasound scan (daily- to look for any evidence of leakage).

Both arms will receive standard care which will include observation, symptomatic treatment including paracetamol for fever and domperidone for vomiting and management of complications of dengue infection (i.e. iv fluid bolus, dextran or blood transfusion depending on the type of complication).

Participants, health care providers, data collectors, outcome adjudicators, data analysts will be blinded to the therapy received.
