is a specific phobia
, an irrational fear of contracting a disease
, from Greek "nosos"
for "disease" (as the 1913 Webster's Dictionary
put it, "morbid dread of a disease"). Primary fears are of this kind are fear of contracting pulmonary tuberculosis
, venereal diseases
, and heart diseases
Some authors suggested that the medical students' disease must be referred to as nosophobia rather than "hypochondriasis", because the quoted studies show a very low percentage of hypochondriacal character of the condition.
