Disasters Fatalism vs. Preparedness
Risk Perception Our response to a real or imagined hazard is a function of our perception of that hazard. In many situations, hazards are ignored or disregarded. In other situations, they are magnified. Some of the factors which govern risk perception include: familiarity, degree of dread, memorability
Applications of Epidemiology (A) Understanding the causes of a disaster (B) Understanding ways of controlling a disaster situation
