Fear of Contamination
Some kids with obsessive-compulsive disorder might be afraid of being dirty or contaminated, becoming ill, or contracting diseases. Thus, they tend to be worried about direct contact with other people or fears of food, dirt, or some things or places that they think to be infectious or unsanitary. These include a public restroom, swimming pool, or crowded events. Also, these people might have the same foods and drinks constantly as they are supposedly contamination-free. [3]
