Can chronic virus infection be a cause of Obsessive Compulsive Disorder (OCD)? If so, in what percent of cases is this true?

This is quite true, and we can tell you that 95% or more of individuals with OCD have a predisposing chronic virus in their central nervous system that is playing into an inherent vulnerability, usually from karmic trauma. That can include some genetic weakness as well. Karma is involved always in shaping the genetic complement when people begin a new incarnation and can influence things along the way to cause further changes. As you know, it is often a confluence of karma as well as current life issues resulting in stressful circumstances that conspire to compound one another. And when you add into to the mix a third influence, such as the presence of a chronic virus which is a kind of attacker, including its consciousness and the way it is sensed within the body, that can create a perfect storm of negative energies to tip the balance into a symptomatic malady forming. So there will be many CNS conditions you will find through your probing which are initiated by the presence of a virus causing them to manifest with symptoms that otherwise would not have taken place were that negative intrusion not be present.
