摘要

To the Editor: We conduct com-municable disease risk assessmentsafter humanitarian emergencies,including natural disasters, and wouldlike to clarify the findings of Floret etal. (1) regarding the risk for epidemicsin certain disaster settings. Naturaldisasters that do not result in popula-tion displacement, regardless of typeof disaster, are rarely associated withincreased risk for epidemics.However, large-scale population dis-placement, with consequent over-crowding in temporary settlementsand disruption of water supply andsanitation, are indeed associated withincreased risks for communicable dis-ease transmission. This distinction iswell documented (2–4). Increasedcommunicable disease incidence afterflooding and cyclones has been par-ticularly well described (5,6). In addi-tion, after a disaster of any type, epi-demics may go undetected because ofpoor surveillance or because baselinesurveillance data for diseases (such asdengue fever or malaria) are unavail-able
