Contamination OCD: more than germs

What people fear

• Germs, viruses, or getting sick
• Making someone they love sick
• Chemicals, cleaning products, or bodily fluids
• Feeling "dirty" in a way that isn't physical: after a thought, near a certain person, or in a certain place

The rituals

• Washing hands or showering many times, or in a specific way
• Cleaning objects or surfaces over and over
• Avoiding public places, door handles, shared objects, or certain people
• Changing clothes after going out
• Asking others to wash or to follow rules

The cost

Hands can crack and bleed. Hours disappear. Some people stop leaving home. Families often end up following the rules too, which makes the OCD stronger.

What helps

ERP helps people gradually touch what they fear and wait, without washing. It's always done step by step, with a therapist, starting small. Normal hygiene stays normal. The goal is to stop washing because OCD demands it.
