nosophobia

Some people may have nosophobia: the fear of contracting a disease or virus.

His superstitions were accompanied by a series of phobias, particularly pyrophobia and nosophobia.

This has been termed medical student's disease, nosophobia, hypochondriasis of medical students, and medicalstudentitis."

Some authors have suggested that the medical students' disease should accurately be referred to as nosophobia rather than "hypochondriasis", because the quoted studies show a very low percentage of hypochondriacal character of the condition.

Nosophobia 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").
