Nosophobia is the irrational fear of having a specific disease.

The origins of the word Nosophobia come from ‘nosos’ and phobos which mean disease and fear in Greek.

In recent years, nosophobia has also been referred to as cyberchondria. This stems from a lot of the information that is at the root of the fear is found in "cyberspace."

Risk Factors

  • Exposure to high levels of media coverage about disease and the risks of contracting diseases
  • Having suffered traumatic health problems in the past
  • Repeated exposure to people with serious illnesses

Nosophobia appears to be more common among students and researchers who spend a great deal of time reading about specific diseases. These conditions are often called "medical student’s disease."

Relation to Hypochondriasis

Nosophobia is related to hypochondriasis, but there are several important differences between the two conditions. The most important difference is specificity.

A person with hypochondriasis has several physical symptoms that he or she fears may be caused by illness. Someone with nosophobia, however, is afraid of a specific disease and becomes convinced that he or she has the symptoms of that particular disease.

However, not everyone who is afraid of getting sick or contracting a contagious illness suffers from nosophobia. Those who suffer from this phobia exhibit symptoms that can cause limitations in their lives.

Illness Anxiety Disorder

Many mental health specialists have termed both nosophobia and hypochondriasis as illness anxiety disorder.

In fact, many people across the globe have been diagnosed with this condition, which can become debilitating as the sufferer is convinced that he or she has contracted a certain illness.
