Contamination OCD is intrusive fears about germs, dirt, illness, or chemicals, followed by compulsive washing, cleaning, or avoidance to neutralize the fear. The fear is rarely about the contaminant itself, it's about the mental relief washing provides, which then trains the brain to need more washing. The clinical fix is ERP: Exposure and Response Prevention. You expose to the feared contaminant (a doorknob, a public surface, an object you've labeled gross) and then prevent the response: no washing, no checking, no mental review. Bia structures these as a ladder, paced by you, with built-in tracking of avoided compulsions.
Common signs of contamination OCD
- Intrusive thoughts about germs, dirt, or illness
- Washing or cleaning rituals: handwashing, showers, surface cleaning
- Avoidance of public spaces, surfaces, or contaminated people
- Mental rituals: silently neutralizing contamination thoughts
- Checking for signs of illness
- Asking for reassurance about whether something is contaminated

Retraining the Brain
Read the science behind recovery
Anxiety is the brain's natural alarm process out of balance. When we avoid a trigger, the brain learns the threat is real, and will trigger more discomfort next time, creating a vicious loop called the avoidance cycle.
Bia uses ERP (Exposure & Response Prevention) to help the brain unlearn fear through small, incremental exercises. Instead of reacting to triggers, build skills with proactive practice.
Bia provides pre-built recovery plans made of 80+ interactive activities for you and your child to complete at your own pace.

Frequently asked questions about contamination OCD
Is contamination OCD the same as being a clean person?
No. Clean people clean; OCD makes you clean to relieve anxiety. If skipping a wash causes distress for hours, that's the diagnostic line.
What about real contamination concerns like COVID or norovirus?
Bia teaches you to follow public health guidance, not your fear. Wash when public health authorities recommend; don't wash to relieve anxiety. The line is functional, not perfect.
Can I do ERP at home alone?
Yes, Bia is built for it. ERP works as long as the exposures are real and the response is genuinely prevented. The app structures both.
What if my compulsions are mental, not physical?
Bia treats mental rituals too: counting, neutralizing thoughts, mental review. The response prevention is internal, but the structure is the same.
What age group is Bia for?
Bia for Kids is designed for children aged 5 to 12, with a parent guiding the way. For ages 13 to 17, Bia for Teens gives your teen the standard layout while you keep the parent PIN.
Can I use Bia by myself?
Yes. Bia is designed to work as a self-guided tool. It provides a personalized recovery plan, interactive lessons, and step-by-step guided exercises for practicing evidence-based recovery techniques.
Can I use Bia with a therapist?
Yes. Bia provides a provider portal where therapists can monitor your progress, create custom exercises, and support your recovery journey.
How much time does it take?
Individual sessions are short. We recommend 10–15 minutes a day, 3 to 4 times a week. Bia builds a personalized step-by-step journey based on your unique needs, so completing the full journey is different for everyone. Typically, a journey includes over 55 exercises and 19 lessons across 9 milestones.
What do you do with my data?
