Bacteriaphobia

An abnormal and persistent fear of germs.

Sufferers from bacteriaphobia experience undue anxiety even though they realize that most germs are not pathogens (disease-causing germs).

To avoid germs, they may repeat cleaning rituals, such as washing their hands or face.

(Surgeons may do well to have a mild degree of bacteriaphobia.) 'Bacteriaphobia' is derived from the Greek 'bacterion' (staff) and 'phobos' (fear).

The Greek word for 'staff' was chosen because some bacteria (bacilli) are rod-shaped, like a staff.

Alternate spelling: Bacteriophobia.

Alternate name: Bacillophobia.
