Contamination OCD

The subtype of OCD known as contamination OCD is characterized by frequent and distressing intrusive thoughts related to dirt, germs, illness, bodily fluids or other feared forms of contaminants. Dirt, germs, and bodily fluids are often a trigger for individuals struggling with fear of getting or spreading illness. An individual may be afraid of contracting a life-threatening illness themselves or spreading an illness to others and being responsible for harm coming to them. The COVID-19 pandemic has made these fears even more challenging for many struggling with OCD. Other common obsessions in contamination OCD are fear of contact with chemicals and the fear of contact with parasites causing an infestation. Frequently, individuals report fear of contracting and spreading bed bugs or lice.

Common areas of avoidance with contamination OCD are crowded public places, public restrooms, health care facilities, being around young children, the elderly, or individuals with compromised immune systems, and using public transportation. Those struggling with contamination concerns may engage in compulsive behaviors such as excessive grooming routines, frequent hand washing, barrier use, excessive use of household cleaners or sanitizers, checking or inspecting items for signs of contamination, throwing away items for fear of exposure to contamination, and frequent reassurance seeking from others around cleanliness or safety.
