Criteria for a cliical diagnosis of dengue - all of the following:
(1) residence or travel to an area endemic for dengue
(2) fever (temperature >= 38°C or history of fever lasting 2-7 days)
(3) 2 or more additional clinical findings (see below)
(4) exclusion of other diagnoses that explain the findings better
• Illness during a dengue outbreak might be more flexible.
Additional clinical findings:
(1) nausea and/or vomiting
(3) aches and pains
(4) tourniquet test positive
(6) any warning sign (see below)
(1) abdominal pain or tenderness
(2) persistent vomiting
(3) clinical fluid accumulation
(4) mucosal bleeding
(5) lethargy or restlessness
(6) hepatomegaly > 2 cm
(7) increase in hematocrit (hemoconcentration) AND sudden decrease in platelet count to < 100,000 per µL (thrombocytopenia)
Laboratory confirmation requires some form of evidence:
(1) positive RT-PCR reaction
(3) IgM anti-dengue antibody
