Disaster Health
Disaster health covers the health consequences of emergencies and the health-sector response. Candidates must understand the epidemiological transition in disasters (communicable disease risk rises with displacement, crowding, and disrupted water/sanitation), surveillance and early warning (EWARS), outbreak investigation, and case management. Know the core health response components: emergency medical care, triage, referral systems, mobile health teams, and continuity of essential services (immunization, maternal and child health, chronic disease, mental health). Understand mass casualty management, dead body management (dignified, safe, and not a major disease vector), and psychosocial support. Familiarity with Sphere health standards, essential medicines lists, and health cluster coordination is expected.
Common traps: overestimating the epidemic risk of unburied bodies (bodies rarely cause outbreaks; the priority is dignity and identification); assuming disasters always produce epidemics (risk depends on context); neglecting non-communicable and mental health needs; confusing triage priorities.
Rule of thumb: In disaster health, prevent the preventable - prioritize water/sanitation, surveillance, and continuity of routine services. When a question describes crowding and disrupted sanitation, the highest-yield intervention is usually WASH and surveillance, not mass vaccination. For dead-body questions, choose dignified management and identification over disease-vector panic.
