Infectious diseases following major disasters.

A recent surge in the general awareness of the extent of disasters has increased concern over the adequacy of our state of preparedness for these events. Outbreaks of infectious disease after a disaster may have significant societal impacts. In preparation, rescuers must anticipate and identify infectious risks, isolate and treat the individuals with infections, and institute measures that will prevent the further spread of infectious diseases. Epidemiological factors may contribute to the spread of infectious disease after a given disaster. A simple microbiological laboratory in the field may be helpful in attempting to direct therapy at specific infectious etiologies. Prior post-disaster experience suggests that mass immunization may not always be valuable in protecting against disease spread acutely, although immunizations may be considered in a limited number of situations. Disaster medical personnel should prepare themselves with appropriate vaccinations and remain in good health; new pathogens must not be brought in by well-meaning relief personnel. Disasters often occur in a Third-World setting where resources are limited and often compromised. Complete recovery from infectious disease outbreaks and restoration of infection control practices may take years when a Third-World population has suffered a major disaster.
