||In part because of
this lack of data, most epidemiologic studies have concentrated on
tornado-related deaths, which are more easily measured and less numerous
than tornado-related injuries. Morbidity studies following tornadoes have
been limited because victims seek medical care in many diverse locations and
because patient-care documentation during a disaster may not be a priority
for emergency responders (38). In addition, very little research has
been done to relate the physical characteristics of a given tornado (e.g.,
wind speed, width, duration, etc.) with the tornado's public health effects.
Studies to determine optimal tornado-warning dissemination strategies are
lacking, and the potential for new media technologies such as satellite
transmission and cable television to disseminate storm warnings effectively
has not been thoroughly evaluated.
