Anxiety disorder is the root of many phobias in children, so if your child suffers from anxiety, he/she might soon pick up germaphobia more so than kids without anxiety disorders. Some children suffer from both OCD and germaphobia, so their impulsive cleaning pacifies both their anxiety and germophobic reactions. And that’s the reason why many mental health professionals also diagnose patients with OCD. Also, if someone obsesses over worries of sickness or infections, they possibly suffer from OCD too. They exhibit similar symptoms like germaphobes like extreme body, possessions, or personal space cleaning, avoiding public situations, and so on.
