Mysophobia

Mysophobia or misophobia (from Greek mysos, "dirt") is the fear of being contaminated with dirt or germs. Other terms for this phobia are molysmophobia/molysomophobia (fear of being contaminated with dirt), verminophobia (fear of germs), germophobia/germaphobia (fear of germs), spermatophobia/spermophobia (fear of germs), and rupophobia (fear of dirt). Sufferers would wash hands constantly, almost everytime when he/she touches something that could be contaminated, as well as cleaning especially with the use of disinfectants. The most exclusive cause of mysophobia is getting real sick and then learning that germs are the culprit. Dirt may associate with germs, since germs thrive more readily in dirty environments than in clean environments. So sufferers would stay in clean environments to reduce catching dirt and germs.
