Can you get lice (body lice, head lice, pubic lice) by trying on clothes, hats.... or by using a public toilet room?

Germophobia: This is the same question as your others, this time about lice. Like warts, only by intimate contact with another person, not through clothing or contamined environment. Abnormal fear of contagion (germophobia) can be an early sign of serious mental health disability (see "The Aviator", the biopic of Howard Hughes, for a good example). You might benefit from professional counseling about this.
