Is chronic fatigue caused by chronic viral infection, and if so, in what percent of cases?

We would say that roughly 60% of the time, this is a consequence of chronic viral infection causing changes that lead to fatigue, stemming from toxic products of the immune system, and in some cases, other cell products released by cellular damage. There are many, many, causes of profound fatigue. It is a common echoing of karmic trauma because there are so many tragic circumstances leading to overwhelm and exhaustion, and this can be coupled with states of physical impairment, like starvation, severe dehydration, forced hard labor, and so on. And those consequences can be reproduced by cellular consciousness following a reawakening of old trauma, even from other lifetimes, and the body may attempt to relive those hard times in a physical sense it is capable of producing. So regardless of the cause, the best treatment is use of the Lightworker Healing Protocol and the Deep Subconscious Memory Reset protocol because they work on karma of all kinds, as well as the more physical end product symptoms, so everything is covered, including removal of invasive organisms of all kinds which can be debilitating.
