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.
