Is cfs contagious?

No: Chronic fatigue syndrome (cfs) is not contagious. Cfs is thought to be caused by abnormalities in brain chemistry and therefore you can't "catch" it from someone. However, some diseases that cause fatigue are contagious; eg, viral infections like mononucleosis.

No: Cfs or chronic fatigue syndrome does not have a known cause. One theory is that a possible trigger of cfs may be viral. However, even if this were so, the original viral infection would have occurred well before the onset of cfs symptoms and would not likely be contagious.
