The present invention relates to a moisture detection system which takes the form of a covering to be applied to the patient's skin, and to a monitoring system for monitoring a vascular access for a blood-treating apparatus. The covering of the moisture detection system has a flexible substrate material to which an electrically conductive structure having printed conductors is applied as a moisture sensor.
