I had three warts on my nostril for about 5 or 6 months. I think that I might have gotten it by doing jiu-jitsu- I decided to treat it with OTC syllic acid about two weeks ago. I'm now paranoid that I will spread this to my children and wife. I want to know how contagious these warts are iv been looking on line and get so much conflicting information I don't know what to believe I'm so paranoid about infecting my family how do I keep everything clean someone please help me.
