How Is Head Lice Spread?

Head lice is very contagious. Being in close contact with someone with head lice can almost guarantee that you will catch it. As this article suggests  selfies are a big contributor to the spreading of head lice. I am never going to suggest that people stop having fun, but if you know that you have head lice, share the information so that others can decide if they want to be in such close contact with you.
