Hospitalizations aboard aircraft carriers were examined to ascertain differ
ences in illness type attributable to theater of operations and combat depl
oyment status. Percentage distributions and lengths-of-stay statistics of m
ajor diagnostic categories are provided and compared between Vietnam combat
support and peacetime modes of operations and between Western Pacific and
Mediterranean theaters of operations. Respiratory disease proportions were
found to be significantly higher for Vietnam combat support deployments tha
n during subsequent peacetime deployments. For peacetime deployments, the W
estern Pacific deployments had higher percentages of infective, respiratory
, and skin disorders. whereas the Mediterranean theater had a larger propor
