"Dengue & Dengue Haemorrhagic Fever — give a one-line definition and the single most important immediate risk."
Model: Dengue is an acute mosquito-borne flaviviral illness caused by four antigenically distinct serotypes (DENV-1 to DENV-4), transmitted mainly by the day-biting Aedes aegypti mosquito (also A. albopictus). It is the most important arboviral disease of humans, endemic across the tropics with ~96 million symptomatic cases a year (about 390 million infections). The clinical spectrum runs from undifferentiated fever through classic
Station 1 — Pathophysiology (2 min)
Explain the mechanism chain from cause to clinical features and one major complication.
Station 2 — Clinical diagnosis (2 min)
Classic presentation, atypical groups, named bedside signs, and what you examine for red flags.
Red flag cue: High fever, retro-orbital headache, severe myalgia, rash and thrombocytopenia in the monsoon season - dengue; NS1 antigen (first 5 days), IgM after
Station 3 — Investigations (2 min)
First-line tests, definitive tests, and any named score with exact components.
Station 4 — Emergency management (3 min)
ABC priorities, first drugs with dose and route, procedures, and when to escalate to ICU/theatre.
Station 5 — Definitive / long-term care (2 min)
Stepwise definitive therapy, monitoring, complications of treatment, follow-up.
Station 6 — Special populations (2 min)
Child / pregnancy / elderly / immunocompromised / renal impairment — what changes.
Station 7 — Evidence & pitfalls (2 min)
Landmark trial or guideline name if standard; three classic exam traps.
Station 8 — Rapid-fire pearls (1 min)
Five high-yield facts a candidate must not forget under time pressure.
Examiner pass criteria
- Speaks in mechanisms and numbers, not vague lists
- Gives at least one exact dose or threshold
- Names escalation criteria
- Avoids dangerous delays (imaging when unstable, etc.)
